Selecting guide for the bottom of the mountain climbing, what sweat underwear is wearing the mountain?

When I started climbing the mountain, I also wore cotton T, because the schedule was short, most of them ended in a few hours, so I didn’t think that cotton T was not good. However, as the time climbing was lengthened, the altitude gradually increased. Slowly found that cotton T was very easy to suck sweat, and it was not easy to dry. When you stopped to rest, a cool breeze would feel super cold!

Because the cotton T is wet, it loses warmth. Even if we wear a windproof jacket outside, it will still be cold because sweat accumulates the body temperature. Later, when I came into contact with the bottom layer of the mountain climbing, I felt that I met and hated it late ~

The characteristics of sweating clothes at the bottom of the mountains absorb and dry, so that the body can keep the body in a dry state at any time and maintain the constant body temperature.


However, there are many types of clothing on the bottom of the market on the market. How can I choose it? This article will introduce the four major materials and mountaineering itinerary for each material for the four common materials of the mountain.


Know the 4 common underlying clothing materials

The bottom layer of mountaineering on the market is mostly composed of synthetic fibers and natural fibers. Among them, synthetic fibers are divided into polyester fibers, elastic fibers, and nylon. Natural fibers are divided into wool, cotton, and silk. Dry, silk texture is easy to scrape and low durability, so the two are less used to make mountain climbing underwear.

The advantages of synthetic fibers are cheap, dry, wear -resistant, and easy maintenance. The disadvantage is that after wetness, it will have the function of wet and cold, no bacteriostatic deodorization.

The advantages of wool are strong temperature control (warm winter and cool in summer), bacteriostatic deodorization, UV, light weight, disadvantage is that the price is higher, slower after water absorption, not easy to maintain, and shrink after cleaning.

synthetic fiber

Also known as polyester, polyester fiber does not absorb water itself, but to make the fiber a capillary through special weaving, adsorb sweat from the skin into the fabric, and then evaporate the sweat by body heat production.

Because of this, polycatis fibers have the characteristics of fast dryness and good breathability, can keep the skin dry, and it is very suitable for the stuffy and humid climate. But the disadvantage is that it is easy to generate static electricity in a dry environment.




Good breathability

It’s easy to clean and not wrinkle, shrink





After wetting, there will be a sense of wet and cold

No bacteriostatic and deodorizing function

Easy electrostatic

2. Elastic fiber

Also known as spandex SPANDEX or Lycra LyCra, it is very elastic, and the extension can reach 500%. It is often blended with cotton, nylon or polycatis fiber, but because of high deformation, it usually only accounts for a small part of the proportion of clothes.

Good elasticity

Good elastic reply rate is good



High deformation

3. Nylon


Also known as nylon, because nylon is a natural fiber -based synthetic fiber, it is very suitable for other fiber blended as a high -quality and durable composite fiber.

Nylon has the characteristics of strong toughness and wear resistance. It is suitable for the terrain that requires hands and feet and climbing rope. However, because the material is not heat -resistant, try not to wash with high temperature water. Remember not to use iron after washing!


Wear -resistant

Light weight

The price is higher than the polyester fiber

Insect -resistant, mildew

Not easy to static, wrinkle

Not heat -resistant

Natural fiber

Is the difference between traditional wool and Merino wool?

Traditional wool

Beautiful Nuo Wool

The wool of the bottom of the mountain is not the traditional thick and furry wool on the left, but the soft and beautiful Merino Wool of the upper right!

The disadvantage of traditional wool is that it is very heavy and itching. Merino wool is light weight, bacteriostatic resistance, good temperature control (warm and cold in winter), and has a natural anti -UV function, which can achieve sunscreen. It is very suitable for long days or high altitude hiking.

So how to distinguish between traditional wool and Merino wool?

The diameter of Merino wool is below 25 microns, which is suitable for personal clothes. Traditional wool is about 30 microns, which is more suitable for coats. But it is difficult to distinguish the diameter with the naked eye, so the easiest way is to try on!

If you wear a wool sweater to make you feel uncomfortable and tie, it means that the fiber is more than 30 microns diameter, and it is probably not a pure Merino wool.

Traditional wool


After wetness, it still has warmth effect


There will be a sense of itching

Anti -odor is not as good as MERINO wool

Merino wool

Excellent temperature control (warm winter and cool in summer)

Antibacterial anti -odor


Anti -UV


High price


Not easy to maintain

Improper cleaning and shrinking

Clarify your schedule


After understanding the above four common climbing materials, then you must figure out what your itinerary is?

If it is a low -altitude mountain area or a single -day itinerary of three or less than 3000 meters, a polyester fiber or nylon is selected.

If it is a high -altitude mountainous area or long -term traversal of high altitude mountains or more, a wool sweater is selected.

Summer, low -altitude mountain areas under 3000M, single -day itinerary


This is a summer model of Mammut. The polyester fiber content is as high as 97%. The remaining 7%is elastic fiber. It is very breathable and elastic when wearing it. Or wear a single -day itinerary.

Selection of the bottom of the mountain climbing

Winter, high -altitude mountainous areas above 3000m, long days of number of days

The wool content of the Icebreaker is as high as 87%, and the remaining 13%is nylon. It is strong in temperature control. It is really warm in winter. Although it is quite breathable in summer, I think it will still be a bit hot. Wear it alone.

If it is a long -day itinerary that cannot be bathing, it is also recommended to wear woolen sweaters, because wool has keratin that can inhibit bacteria to break down sweat and achieve the effect of deodorization. You should not want to walk to you in the end.

Consider other detail design

Sewing design

The stunning toughness of the mountaineering clothes is strong and mostly uses a flat stitching method, which can avoid the discomfort caused by rubbing the skin.

Site stitching, comfortable tailoring

The hiking sweaty jacket will use different intensity and material fabrics in different parts. For example, the wet and humid parts such as underarms and backs will be spliced ​​with high breathable cloth. Stir with high -intensity fabric. At the joint joints, the tailoring is also specially designed, so it will not feel uncomfortable to wear.

Half chest zipper

Half -placket can be zipper on the chest, which can change the temperature with the weather, and it is more convenient to wear and take clothes.

Cusk thumb design

I like the design of the cuff thumb hole, because it can keep the palms with some warmth effect, and when wearing a jacket, I can prevent the sleeves from rolling up!


Four underlying sweats on the market are polyester fiber, elastic fiber, nylon and Merino wool.

Polyester fibers are cheap, breathable, fast, and are suitable for walking in summer or low altitude. The disadvantage is that it is easy to generate static electricity.

Elastic fiber is good but easy to deform, so it is often blended with other materials, and the proportion is also low.

Nylon toughness, durability, not easy to wrinkle or static electricity suitable for pulling rope climbing. The disadvantage is that it is not heat -resistant and the price is higher than the polyester fiber.

Merino wool is light weight, bacteriostatic deodorization, anti -ultraviolet and good temperature control (warm winter and cool in summer), suitable for winter, long days of schedule or high altitude mountain area. The disadvantage is that the sweat absorption is slower and the price is higher.

The above is the choice method of climbing bottom clothes. Recommended for your reference!









Light weight

The price is higher than the polyester fiber
