Even in winter, you sweat a lot while climbing, so hydration is essential. However, in a freezing environment, cold drinking water can cool your body. Furthermore, when climbing in low temperatures, cold drinking water often freezes. At such times, a warm drink will relax your body, which has been cooled down to the core, and revitalize your mind and body.
A water bottle that is excellent for keeping warm and cold is useful in winter outdoor scenes. Many people probably store them in their bag's side pockets. As it is called "heating and cold-intaining", it keeps it cold, making it a great product not only in winter but also in summer. Unlike in the past, in recent years there has been a wide variety of models that can be used, from everyday use to camping, leisure, and even for full-scale mountain climbing. Each has its own unique design and functionality, but this time we decided to determine the strike zone, mainly for outdoor and mountain climbing water bottles.

Impressions of each model
It's not just the design that surprised me: FLSK bottles
FLSK shows overwhelming heat retention and design. The simple parts and slim drinking style are also attractive.
A water bottle with a stylish design that has never been seen before. The editor-in-chief of our website fell in love with me at this year's ISPO and finally gave it a try. In addition to the manufacturer's own stainless steel vacuum two-layer structure, the internal copper-coated walls further enhance heat retention. The manufacturer's slogan is that it keeps the product warm for 18 hours and 24 hours cold, but there's almost certainly no doubt. It was by far the most temperature-keeping ability we tested. Made from high-quality stainless steel, it can get rusty and easily remove dirt. It has the performance that prevents the color transfer and odor of coffee, which is often common, from coffee to leave behind. Simple structure with only the bottle body, lid and gasket. Because it's a slim bottle, it may be a bit difficult to wash the inside, but with ingenuity you can do it, and it's super easy to use the special cleaning beads. Speaking of desire, I wish the body had grip.
Total high level of perfection: Hydro Flask 18 oz Wide Mouth
Despite its wide drinking style, it has good heat retention and is easy to maintain and use.
A water bottle with an impressive charming logo design. The double-walled vacuum insulation structure of stainless steel allows it to maintain a maximum of 24 hours of cooling and a maximum of 6 hours of heating. The surface does not condense due to the temperature difference. Made of 18/8 stainless steel, which is highly durable and rust-resistant. The cylindrical shape keeps your drink delicious and makes it easy to maintain. The material does not contain any bisphenol A (BPA), which has a negative effect on the human body. The surface of the bottle is treated with a unique powder coating, making it easy to grip even with wet hands and non-slip. The flexible and durable strap is large enough to hook into your hand, making it perfect for your hands. The lid is a honeycomb insulation cap that maintains the temperature inside the bottle. However, the slight downside is that it is prone to dripping when the lid is opened.
Combining design and usability: SIGG Hot & Cold One 0.5L
In addition to basic high performance, it has also been designed with ease with a single touch to make it easy to drink.
SIGG is a specialized metal processing manufacturer founded in Switzerland in 1908. The well-established water bottle has a refined design that has won the German Good Design Award "GERMAN DESIGN AWARD WINNER 2016." This is a great usability that allows you to use one-touch operation with one hand when vomiting (even while wearing gloves). This is a particularly impressive feature in the outdoor scene. It uses 18/8 stainless steel, which is rust-resistant and highly durable, and has a vacuum double structure made of stainless steel that enhances heat retention. The metal zirconium contained in the main body combines with the oxygen and moisture in the vacuum layer, increasing the vacuum effect that prevents heat and cold air from inside the container from escaping. Furthermore, the inside of the vacuum surface is coated with copper, which maintains even higher heat reflectivity inside. The heat retention effect is 6 hours at 68°C. It is highly appreciated that it can be used with one hand, but it is undeniable that it may be a bit difficult when cleaning.
A sturdy and robust functional beauty is sharp: Klean Kanteen TKPro 0.5L
It is designed to be heavy and rugged, but its heat retention and simple and easy-to-use parts are attractive.
It comes with a sturdy stainless steel cup, making it slightly larger and the heaviest of this time (irrelevant). This water bottle has a rugged, cool, and simple shape. The cap uses Pore-through technology that can be poured with a slight twist. It can be poured from any position 360 degrees. The cup also has a double wall structure, and has a shape that fits comfortably in your hands. You can easily use it even while wearing gloves. The Klean Coat™ used is four times stronger than traditional powder coats. The rough surface of the bottle has a high grip and is also positively rated. No plastic is used and the vacuum insulation structure is made from 18/8 stainless steel and silicone only, with Climate Lock™ double wall. The inside of the bottle is electropolished, so there is no harmful manufacturing process, and of course it is BPA-free. The smell does not easily transfer, and the large bottle makes it easy to maintain. If it comes with a cup, you should choose this first.
Not only is its performance but its environmental awareness high: MiiR WIDE MOUTH 16oz
It is made to cool down a bit, but it is simple and easy to use.
A simple water bottle with a double-wall vacuum insulation structure. The inside is made of 18/8 medical grade stainless steel, which does not have a metallic smell. The exterior is also coated with a hard shell powder coat that is easy to hold. It is BPA-free and the lid is easy to hook into your hand. It's easy to use even in outdoor situations. The bottle is made from Temp Deflector™ technology to prevent temperatures from being released outside. It's nice that it's simple, but perhaps because it's a wide mouse with ice cubes, it has a great contact with the outside air, and I feel like it's not as effective as it keeps the heat and cold. The initiative is a rare bottle that has been applied to a clean water and health project where a portion of its sales can be tracked, supporting areas that are unavailable for water, education and more around the world.
Pursuing high performance, lightweight and durable: mont-bell Alpine Thermo Bottle 0.5L
It's easy to handle even when wearing gloves, and is resistant to impact, making it the most comfortable to use in the mountains.
It is a compact climbing bottle with a cup cover. The surface of the main body is made of SUS304 stainless steel, which is highly strong, and the inner surface is made of SUS316 stainless steel, which is resistant to corrosion. It is also treated with a reflective coating to prevent heat flow, and for about 6 hours, both the heat and cold are as expected. Simple structure even with a cup. Easy to use in everyday life and in the field. To use it, loosen the inner plug, pour the drink inside onto a cup cover, then eat it. The cup cover and bottom cover are made of silicone, which gives it a very stable feeling when placed. This is a very nice detail for outdoor use, such as outdoors. The point deduction is that the looseness of the inner plug is a bit difficult to understand.
Multi-use combination of high performance and ease: STANLEY Go Series Vacuum Bottle
The design and ease of drinking are outstanding, but the heat retention is inferior to other products.
Stanley's multi-use model, the Go Series. It has a vacuum insulation structure, and takes 6 hours at 57 degrees or higher. Although it keeps it at 8 degrees or below 6 hours, it may be a little weaker than other companies. The mouthpiece is 6cm in diameter, large enough to easily hold home ice. It has a lid and bottle body structure, making it easy to clean. Dishwasher safe too. However, it may be a little large to store in the side pockets of your backpack. The lid is made of the latest synthetic resin tritan. It is a skeleton type that allows you to see the contents and is equipped with finger loops, making it easy to carry. For the lifetime warranty, the price is reasonable at around 3,500 yen. As an entry model, it is an affordable model, but I would like to see some ingenuity in terms of heat and cold retention.
A long-selling experience with a proven track record in mountain climbing: Thermos Stainless Steel Bottle FFX-500
No matter what, it is a long-selling product that has moisturized climbers' throats for a long time.
The "Mountain-only Thermos" has a body ring that is easy to use even when wearing gloves. The body has a 36mm diameter. The stainless steel vacuum double-layer structure keeps warm (room temperature 20 degrees) above 77 degrees for 6 hours. The silicone ring on the body is easy to grip and also reduces damage when it falls. The silicon bottom cover at the bottom also suppresses impact when it falls. It has been designed to prevent damage to the body. In addition, the non-slip cup with a wide bottom and stable shape, with a high holding capacity is non-slip and easy to handle even when wearing gloves. This bottle has a variety of features unique to outdoor scenes. However, the double screw sensor is inevitably complicated compared to other companies. Negative in terms of care. I hope they will also pursue simplicity.

On the previous page, we introduced a ranking of the models we compared, a list of ratings and specs, and recommendations based on them. From here, we will add to the criteria used to evaluate the evaluation (especially usability) and why it was evaluated in this way.
Detailed reviews of each item
Drinking tip
Due to the structure, if the drinking opening is large, the chances of the drink getting exposed to the outside air will increase. Not only is it easy to drink, but I think a slim drinking mouth is better for keeping it cool and warm. In this regard, due to its structure, FLSK and SIGG are not easily exposed to the outside air and have a high sealing property, and even if the cap is opened and closed, the drink inside is less likely to be affected by the temperature of the outside air. However, don't forget that it takes a little effort in terms of maintenance.
While models with a wider mouth are easier to pour and drink, note that the more you drink, the more the actual heat retention is less than the specs.
Grip properties
In autumn and winter, I often use water bottles while still wearing gloves. So, you can't overlook the grip when you hold the bottle. This lineup has a noticeable lineup that has a rough texture on the surface of the bottle, increasing grip. Klean Kanteen and Miir have only coated the body and cap, while Hydro Flask and STANLEY have only coated the body.
The powder coating on the surface makes it easier to grip. The Clean Canteen uses Klean Coat, which is even more non-slip and durable.
Simple structure
The bottle structure is simply simple. It's easy to handle and easy to maintain. It's a bit of a hassle to disassemble and it's a bit of a pain to take care of it. Given the overall specs, the main favorite is FLSK (flask), and if it comes with a cup, Klean Kanteen (Clincanteen).
Clean Canteen is made from stainless steel, and is made from simple and small parts with little bumps. The FLSK has a thin drinking mouth, but the parts are very simple.
Of course, Hydro Flask, Miir, and STANLEY also have a simple passing line.
Shock resistance
With this lineup, there doesn't seem to be much difference between the body materials themselves, but Thermos and mont-bell have silicone covers. Especially when using outdoors, there are fields that lack stability due to the outdoors. By preventing damage to the body surface due to dropping, the body itself lasts for a long time. It's also good that you can replace the silicone cover!
Thermos and Montbell come with a silicone cover on the bottom and lid that are prone to damage. It can also be removed to reduce weight.
summary
The main favorite is FLSK. I was impressed by the refined, stylish design and outstanding heat retention. The hot hot coffee remains at a temperature that you can feel the heat even after 24 hours. Cleaning beads for cleaning and high-grade stainless steel that are resistant to dirt and rust.
Hydro Flask and SIGG are also recommended high-level lines. Is it the Hydro Flask, which has a wide range of charming logos and colour lines, or a SIGG that can be used with one hand? It depends on your preference. If it comes with a cup, we recommend the Klean Kanteen TKPro 0.5L. It's a little large, but simple and has a strong presence. The heat and cold are also good. Meanwhile, Miir and STANLEY are highly portable and designed, but I hope that as water bottles, they will further improve their heat and cold insulation, which is a feature with a large weight. Conversely, while Thermos and mont-bell have excellent heat and cold retention, they hope for portability and upgraded design.
