My new favorite bottle. Hydro Flask TRAIL SERIES, a cold and heat bottle that you'll want to take out on camping in the mountains.

From Bend, Oregon, Hydro Flask has grown remarkably since its founding in 2009 and has now become synonymous with the insulation bottle category in its home country of the United States. The friendly logo that loosens the mouth and the mouth of the person, the cheerful and colorful use of colors, while the refined and elegant look that eliminates waste, is filled with an "Oregonian" that combines the generosity of the rich nature with the rational atmosphere of a cutting-edge city, and you can't help but feel the charm of its unique and unique sexiness.

The latest lightweight insulation bottle series they launched since last season is the TRAIL SERIES . I'd been checking it for a while, but after seeing the standard mouse type with a narrow mouthwalk finally released this season, I finally got it. As a result, it is very useful from camping in spring to summer to mountain climbing (of course, in everyday life). Even though I had never brought up any insulation bottles outside of the snowy season, I was so attached that I couldn't even begin my journey without it, and I was so attached that I couldn't let go of it.

Of course, it is a basic premise that it is functionally excellent, but that's not the only reason why you're so fond of it. So this time HydroFlask 's TRAIL SERIES standard mouse type .

I love this Hydro Flask TRAIL SERIES

Anyway, it's very light!

The lightness of the bottle is clearly visible the moment you hold it, is it really a vacuum insulated bottle? I think so.

The official website shows 218g, but it seems to be the weight excluding the lid, and in reality, the actual measured 258g including the lid was 258g. That simple Nalgen bottle (1L) costs about 180g, but I think it's a little more slurping than that? That's the impression. Compared to other typical insulated bottles such as Thermos Yamasen Bottle (500ml/approximately 280g) and Montbell Alpine Thermo Bottle (500ml/265g), it is clear that it is light enough when considering its capacity of 621ml. By the way, the capacity is slightly larger than this 500ml, which is a bit more than normal, especially when you want to drink plenty of water, in the summer, and I also like the exquisite size, not too big or too small.

It's not just lightness. I'm so fond of the design and shape that you'll want to have

Before we knew it, our whole family had become HF users, and we had three types lined up in the kitchen every morning: the traditional bottle, the wide mouse with straw for KIDS, and the current TRAIL SERIES.

As you can see from this, the design of the latest series is not the familiar, unique powdered surface with the non-slip, matte texture, but rather the glossy, machined surface coating. Probably because it's lighter in grams. Still, as usual, its simple, lean form and sophisticated coloring remain intact, giving off a cute presence in a backpack.

I took him out and watched it. The earthy colouring, rugged texture of the carved material, and the beautiful straight lines that eliminate waste make it stand out against Mt. Fuji.

With a coffee set. If you're making a special cup that is carefully selected for its flavor, even outdoors, you'll want to pay attention to the dishes too.

It is also well thought out for outdoor use.

It's not only cool, but also very practical, so you don't have to worry about using it not only for light hiking, but also for hard activities such as long hiking, traversing, and stream climbing. For example, the 18/8 stainless steel has a double structure that is lightweight yet has excellent durability and rust resistance. The upper material is extremely thin to reduce weight, and the thickness is made to increase towards the bottom to increase durability, making it a balance between lightweight and durability.

It has a handle that has been removed and lightened to make it lighter, so there is no need to worry about it slipping off without a smooth surface. Also, when stored in the side pocket of your backpack, you can insert the carabiner or strap to avoid any risk of falling.

Tapered mouthfeel makes it easy to drink (Standard Mouth type)

I preferred a narrower mouthpiece than a wide mouse in terms of ease of drinking and pouring, so I was waiting for this Standard Mouth type to be introduced. Personally, I can't drink wide mice, especially while driving (is there anyone who can drink that well?). This will not cause you to panic and slurp out when drinking directly, and it fits perfectly in your mouth.

The heat retention is decent, if not incredible. If you keep it in cold, even in the middle of summer, it's fine during the day

It's not a drawback, but the heat retention performance itself isn't surprisingly high. This is clear when comparing it with the Montbell Alpine Thermo Bottle, which is extremely excellent in terms of heat retention.

• TRAIL SERIES (621ml): Heat retention effect: Approx. 70°C after 6 hours
• Montbell Alpine Thermo Bottle (500ml): Heat retention effect 6 hours after 78°C or more
• Thermos Yama Special Bottle (500ml): Heat retention effect 6 hours later, over 77°C

After adding hot water at about 95°C, I tried again to measure it again 6 hours later. It's hot enough to touch, but the temperature is a bit lacking for a cup noodles.

I poured hot water at about 95°C in the morning and tried to eat Cup Noodles for lunch, but that was a bit harsh (you can do it with an Alpine Thermo bottle).

If you are thinking of extreme uses such as wanting to eat cup ramen without using firearms, or for use in the outdoors during the harsh winter, Montbell, Thermos and other squid-like insulated bottles are the best. However, it is more than enough for drinking-centered needs, such as drinking hot drinks in the winter or drinking cold water in the summer.

summary

When it comes to insulated bottles used in the mountains, we tend to focus on their specifications such as their heat retention and durability, but when we consider using them in outdoor scenes that are closer to everyday life, it becomes even more important to note that they are not only functional, but also friendly and easy to use, and how casual you can use them without thinking about them. In that sense, Hydro Flask TRAIL SERIES is currently the perfect companion for me as I travel between the city and the field, with excellent features (lightweight, highly durable, clean) and excellent design that makes me want to carry it around every day.

If you're greedy, this lightweight series offers even more insulation performance for outdoor use, and if there's a size smaller (18 oz?) for town use, I'll buy both, so be sure to make one.
