Comparative review: A must-have for winter mountains or a daily bottle. We compared the warm and cold water bottles

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.
