If you want to enjoy a quiet hike, try hiking in the low mountains after the leaves have fallen. The appeal of hiking in the so-called off-season is the desolate forest atmosphere, with fewer people walking, the leaves falling and covering the trail, and the wind rustling the fallen leaves. Personally, this is my favorite season.
When I talk to readers at events, I often hear that it's difficult to decide what pants to wear for autumn and winter, or for hiking in snowy mountains. Intuitively, it's easy to imagine that shorts or thin nylon pants are sufficient in the warm spring and summer, but in autumn and winter, it's difficult to imagine what the conditions will be like in the mountains, which may be one reason for this.
The most reasonable solution would be to wear tights under your trekking or rain pants, but that can be too hot or too tight, so it doesn't always work. It's especially unsuitable for times when it's slightly cooler than you'd need tights, and I think many people are troubled by this.
So this time, we looked at all 112 models for trekking pants for the 2025-26 season that have just the right thickness (warmth) and protection for low mountain hikes from early autumn when the weather starts to cool down to January and February, or for snow trekking just before full-fledged winter mountain climbing, or trekking on snow-covered mountains.We selected our own best models, and in the second half of the article we've summarized the points you should pay attention to when choosing trekking pants for autumn and winter wisely.

[Scenes and Preferences] Best All-Round Trekking Pants for Fall and Winter
Best Fall/Winter Trekking Pants: Patagonia Terra Via Peak Pants
As I mentioned earlier, autumn and winter can be a diverse season, from early autumn when the heat still lingers to mid-winter when temperatures drop below freezing, and whether there is snow or not. Furthermore, whether it is a low mountain hike or rocky alpine terrain, whether it is a mountain trail or a variation route, etc.
If we go into detail, there is an optimal model for each, but first let's consider a watch that can be called an "all-rounder for autumn and winter" that can cover as wide a range of cases as possible.
When choosing, the most important thing is that the pants have the basic functions required for trekking.
■ Main features required for trekking pants
-
Breathable to reduce discomfort caused by sweat
-
Lightweight and easy to move, even when lifting your thighs or bending and stretching.
-
Durable and protects from scratches caused by trees, rocks, etc.
-
Quick drying that dries quickly even when wet
-
Windproof and cold-resistant to prevent wind and cold from the outside air
-
Water-repellent, repels some water and dirt
In addition, it is designed for autumn and winter, as it has the heat retention needed for mountain climbing in autumn and winter.
However, if the pants are too thick, they will be too heavy and uncomfortable, and if you use padding that has a high heat retention capacity per weight, it will have less stretch and will affect ease of movement (of course, with equipment, it's all about prioritizing what you wear, so depending on the purpose, padded pants may be better).
In that sense, the best choice here is a pair of trekking pants made from the classic "medium to heavy double-weave soft shell" material, as this is the most basic and versatile model.
The Patagonia Terra Via Peak Pants offer a balanced range of basic mountaineering functionality, making them ideal all-around trekking pants that can be worn year-round. They're just the right thickness and breathable, quick-drying, making them perfect for high-altitude trekking in the summer as well as autumn and winter. The three-dimensional cut and stretchy polyurethane construction provide excellent mobility, and the slim silhouette is a nice touch. While the knees and buttocks are reinforced, they're not too noticeable, which is a plus. The pockets, waist, and hem are also designed for convenience, leaving no stone unturned.
Best trekking pants for Akiyama: Arc'teryx Gamma Pants
Next up are standard trekking pants, but they're a little thicker for midsummer and a little thinner for winter. They're also made of double-weave softshell material and weigh around 350 grams. They're perfect for when the weather isn't too hot or too cold.
At first glance it may seem like a half-baked item, but given the temperatures we've seen in recent years, it seems like it would be just right for trekking from late August to November, so in that sense it's actually a very versatile line.
If I had to choose, I'd say the Arc'teryx Gamma Pants . Honestly, all Arc'teryx pants are amazing. I've worn many pairs of Arc'teryx pants over the years, and I still treasure them. Once you wear them, you'll be reluctant to let them go because of their comfort and high performance. The Gamma series, in particular, has long been a staple of Arc'teryx's softshell series, focusing on mobility for climbing while also being versatile enough for other activities. The ease of movement and silhouette are simply superb, and I can confidently say that they won't disappoint.
Incidentally, I have an unforgettable memory of interviewing Mike Graham, a legendary climber from the 70s and the founder and designer of GRAMICCI and ROKX pants. When I asked him what outdoor products other than his own he was interested in, he gave high praise to Arc pants. I still remember his words, "Their engineering is outstanding and worthy of respect."
Best Winter Trekking Pants: Teton Bros. Absaroka Pant
This time, we're looking at traditional trekking pants that are warm enough to withstand the cold of midwinter without tights. It's best to choose pants that not only use a double-weave soft shell, but also have a brushed or fleece lining. For those who don't like pants that are too heavy, we recommend models that use highly insulating and breathable padding materials (such as Octa or Polartec Alpha) instead of thick brushed materials (although this will sacrifice some mobility).
The " Teton Bros. Absaroka Pant " is a warm and active stretch pant from Teton Bros., a brand that specializes in items for high-tempo activities. What I like most about it is that it's made of a double-woven soft shell that provides ease of movement and durability, while the lining is made of a brushed stretch material. It also features clever draping that increases the range of motion of the knees and hips, and a tapered design below the knee for a beautiful silhouette.
Best and most cost-effective trekking pants for fall and winter: Rab Incline AS Pants
The familiar "high cost performance" model that makes you wonder, "This performance at this price?" Looking at the whole picture, Montbell is clearly the clear winner. It's unsurprising that each pair is priced at over 10,000 yen, and some models even cost less than 10,000 yen, making for an incredibly high price. However, the tricky thing about pants is that even though they're cheap, you might be hesitant to wear a pattern that doesn't fit your body at all. There's always extra room around the waist and thighs, which makes them look a bit unfashionable.
My No. 1 pick here is the Rab Incline AS Pants . I always wonder, is it really okay to charge such a high price for a pair of pants that are so impeccably made? That same admiration extends to trekking pants. This model is so highly functional and well-balanced that it could easily be included in the first category, "Best Fall/Winter Trekking Pants," offering wind resistance, warmth, breathability, stretch, lightness, and a beautiful silhouette. The fact that it has just the right amount of stretch yet doesn't use polyurethane in the fabric is another plus point in terms of durability.
Best Pants for Snow Trekking: NORRONA Lyngen Flex1 Light Pants
The candidates mentioned so far are basically models intended for mountain climbing and hiking in the snow-free season. Of course, most softshell fabrics have a certain degree of water repellency and wind resistance, so light snow won't soak in if you brush it off with your hands, so it's not like you can't wear them on snowy mountains. However, there are also models of pants for this season that are intended for more serious snow and ice activities, such as ice climbing with crampons, mountain ski touring with ski boots, and snow trekking with snow-
We've selected some noteworthy models from this category. Our pick for the best is the " NORRONA lyngen flex1 light Pants ." Norrona offers a range of products specifically for a variety of activities, including skiing, mountain climbing, trail running, and biking, but the "lyngen" series is a piece from a collection optimized for ski touring, which is what we'd call early spring mountain skiing in Japan.
This model uses flex1™, the same breathable, windproof, durable and stretchy material used in many of the brand's technical pants, to ensure comfort and ease of movement in cold weather, while also featuring features such as a gusset at the hem to accommodate snow gaiters and boots, ample pockets and ventilation to accommodate a wide range of activities on the snow.
Best Field & Everyday Trekking Pants: OUTDOOR RESEARCH Timberline Chino Pants
Finally, we checked out a model that not only offers the comfort and protection needed for autumn and winter trekking, but also has a design and silhouette that makes it comfortable to wear in everyday life around town. Personally, this is the model I wear most often in winter.
When it comes to a design that can be worn comfortably in everyday life, there are probably many different preferences, but I personally don't like oversized or extremely tapered silhouettes, so "5-pocket pants" that can be worn to work are my go-to. So, my criteria here are that they have a sophisticated design, are warm and functional.
I mentioned the merits of Arc'teryx earlier, so I've chosen another model here: the OUTDOOR RESEARCH Timberline Chino Pants . OUTDOOR RESEARCH has long been known for its high quality pants that combine functionality and sophistication, and these Timberline Chino Pants have been my favorite for the fall and winter seasons over the past few years.
Made from a sturdy nylon softshell material, it's quick-drying, abrasion-resistant, breathable, and stretchy enough to not restrict movement. Its slim fit and subtle tapered calf help prevent it from looking outdated. While suitable for all seasons, it's a little thin for the winter months, so the Timberline Fleece-Lined Pants, which have the same construction but a brushed fleece lining, might be a better choice for the coming season.

How to Choose: Tips for Choosing Trekking Pants Wisely (Autumn/Winter Edition)
First, let's organize the necessary functions of trekking pants, regardless of the season, while thinking about how they differ from pants you wear every day. Roughly speaking, trekking pants have the following advantages over pants you wear every day:
General characteristics of trekking pants
- Windproof and cold protection to prevent cold caused by wind and outside air
- Lightweight and easy to move around without stress, even when bending and straightening your knees and thighs
- Breathability reduces discomfort caused by sweat
- Durability protects against scratches caused by trees, rocks, etc.
- Quick drying that dries quickly even when wet
- Water repellent that repels some water and dirt
Of course, there is no one pair of pants that has everything perfectly, and although there are inevitably trade-offs to some extent, high quality pants are those that achieve a good balance according to the use and purpose.
For this reason, when choosing trekking pants, it's important to consider what kind of activities you'll be doing most, and then check whether they have all the necessary features. When it comes to trekking pants for autumn and winter, the most important thing is heat retention, but breathability isn't as important. You want pants that offer the same level of ease of movement and durability in all seasons.
Trekking pants have a wide variety of models, ranging from materials to design and details.
Point 1: Thickness, weight, and heat retention of the fabric
You should have a rough idea of how thick (volume) you need for autumn and winter. Long pants can be roughly divided into spring/summer, year-round, and snowy season pants depending on the thickness of the fabric . For autumn/winter trekking pants, you can rest assured if you choose a type known as an " all-year model " or a three-season model (except in the harsh winter). Even though they are all-year models, they can still be too hot if worn on low mountains in midsummer, so it's best to think of all-year models as being primarily for spring and autumn.
Year-round models are generally made with " double-weave softshell fabric weighing around 400 grams or more, " which serves as a guideline when considering thickness. Of course, there will be some variation depending on the fabric's performance, such as a light and warm fabric or a heavy but thin fabric. This guideline is only for general softshell pants. Pants that contain insulation (padded batting) rather than softshell, or pants with a brushed lining, can be light but warm (although this often comes at the expense of stretchiness, etc.).
Point 2: Fit and ease of movement
Form (3D cutting)
The most important thing about trekking pants is that they have a wide range of movement and are easy to move around. However, if it is too loose, there is a risk of your feet getting caught on the hem and falling, and on the other hand, if it is too tight, it will become tense when you bend and stretch it out. For this reason, many trekking pants are made of ergonomically designed three-dimensional cut As you can see from the knee area in the photo on the right, this is designed to allow room in the knee area so that it does not stick even when bent or extended. Depending on the make and model, various other structures that do not interfere with body movement are incorporated into various parts, such as hip shapes and crotch play (gussets) , so try on and compare them to choose a model that fits your body and movement better.
Stretchability
Another factor that allows for natural movement the high level of stretch in the fabric. Highly stretchable trekking pants often contain polyurethane (spandex) and other materials, resulting in a number of models offering surprisingly easy mobility. This allows for natural freedom of movement even in a relatively tight silhouette, ensuring safe and comfortable walking . When choosing pants, the strength and direction of stretch (e.g., stretch in only one direction, vertically or horizontally, or all directions) vary by manufacturer and model, so try them on and bend and stretch your body to get a feel for how they feel and how easy they are to move in. However, be careful of pants that use too much polyurethane just to enhance their stretch. Polyurethane is heavy and degrades over time, so even if it's for ease of movement, it's best to avoid it if possible.
Point 3: Material (water repellency, breathability, quick-drying, UPF, durability, weight)
In addition to the stretching functions listed above, there are various characteristics depending on the material, so be sure to check the following:
Water repellent
DWR (durable water repellent) fabric is very convenient as it can repel some light rain and snow . However, it is not "waterproof," so don't forget to take measures against serious rain.
Breathability, breathability, quick drying
When you're active for long periods of time, your pants will absorb a lot of moisture, not only from sweating in your lower body but also from sweat dripping down from your upper body. Getting wet can be fatal in outdoor activities, so choose trekking pants that are highly breathable, quick-drying, and have moderate breathability . However, when considering trekking pants for autumn and winter, pants that are too breathable will make you feel cold, so it's important to have just the right amount of breathability. In that sense, double-weave softshell pants are ideal for autumn and winter pants, as they block the wind but allow moisture to escape and are reasonably breathable. Of course, chinos and jeans, even though they may be thick and warm, are strictly prohibited as they have poor breathability.
UV protection (UPF) material
UPF stands for "ultraviolet protection factor," which indicates how well a garment protects your skin from UV rays and sunburn. The higher the number, the better the UV protection, but regular clothing naturally also blocks a certain amount of UV rays. If you're really concerned about sunburn, choose pants made from a material with this property .
Checkpoint 4: Details (waist, pockets, hem)
West
The waist of trekking pants can be divided into two types: one with adjustable functions and one without The non-adjustable type has belt loops, so you will need to prepare a separate belt yourself, but that's more flexible. On the other hand, there are various adjustment methods for adjustable types, and the ease of use and range of adjustments are different, so you will need to try them on and check them out. Another thing to note from experience is that if the central button (buckle) is made of thick metal, some people may be able to get sorely pressured by the hip belt of their backpack, so it is a good idea to check whether the belt part is too uneven.
Various adjustment functions. The length is adjusted on the top left by pulling the tape on the left, and the bottom left is adjusted using the attached belt inside. The upper right is only the belt loop, and the lower right is adjusted with the belt loop and the Velcro on both sides.
- The simpler the waist adjustment function, the more comfortable it becomes. Choose one with a simpler adjustment and a simpler fit .
- Try it on and see if it fits。
The pockets are designed to greatly affect the usability of pants, but they actually vary greatly depending on the pants, such as where they are attached, how many, how large, and how there is no zipper. Also, it does not simply serve as a pocket, but also reinforces durability and ventilation (enhancing breathability), so there are many areas where you won't know if you are actually satisfied until you try on them. The only thing I can say is that in terms of ease of use, it's better to have a lot . Sometimes there are modest models that prioritize weight and style, but as a result, they can become just pockets that you don't know what to put in, so be sure to check this out carefully.
Pockets generally have a large number of hips, waist and thighs, but vary in size and number.
- Without considering the weight or shape, it is generally recommended that the pockets have larger pockets and more pockets, making it easier to use and more .
- It's safer to have a zippered pocket to prevent objects from falling out .
- If you are also using it for climbing, check whether it does not fit on the harness belt position .
Drawcord and hook hem
Recently, models with drawcords at the hem that can be tightened are becoming more common, and they are often convenient, but they don't interfere with trekking so I think they're not a high priority. There are three main reasons why they're convenient.
- It prevents the hem from spreading and makes it less likely to hang on your legs .
- Tighten it over the shoes to create a simple gaiter (prevents the intrusion of pebbles and water) .
- You can roll up long pants and wear them as short pants
Some pants also come with hooks that can be hooked onto shoelaces to prevent the cuffs from riding up and to block out pebbles, branches, and debris.Like drawcords, these are convenient features designed for ease of use when hiking or climbing.
summary
If you choose your trekking pants in the same way as you would for everyday pants, you might be satisfied with just the shape and ease of movement, but when it comes to performance for mountain climbing, various functions and features are required of trekking pants. Please use this as a reference when choosing the perfect pair depending on the purpose, season, and location.
