1. The elasticity should be good (comfortable but not tight)

2. The color should be low-key and the style simple

3. Keep warm

When I am financially well-off, I will buy better thermal underwear, such as Shuya Amino 5.0 series

First of all, its color is relatively low-key, which is very suitable for middle-aged and elderly people. I bought it before At that time, I also looked at its ingredients. The fabric ingredients are: 59% acrylic, 6.2% wool added to improve warmth, plus 28.6% viscose, 4.8% nylon and 1.1% spandex.

Viscose fiber has a good thermal insulation effect of absorbing sweat, wicking moisture, and being breathable, while nylon and spandex are used to improve the elasticity of the fabric. My parents said they are easy to wear, but they are a bit expensive. They usually cost 400 to 500 yuan. Now there is an event on Double 12, and you can get them for about 300 yuan. Friends who can afford it can consider buying them.
