Hot underwear really works. Heating underwear is made of a special kind of fiber. It will heat because it will generate heat by absorbing the moisture emitted by the body, so as to achieve the effect of heating. So it's not high-tech, and it won't automatically heat up.

Although the heating underwear will not automatically heat up, the warm-keeping effect is still very attractive. The warm-keeping effect of heated underwear is still very good. Compared with ordinary thermal underwear, it is not much different, but it will heat itself, which is better.

Matters needing attention in purchasing thermal underwear.

When choosing underwear, the first concern is the bottom circumference of underwear. If it is too tight, it means that the underwear size is too small and needs to be increased. If the bottom edge of underwear is easily pulled in, it will cause traces, indicating that the bottom edge is narrow and it is necessary to wear a bra with a widened belt, which can increase the support and fixation of the chest and also disperse and balance the fat in the chest. Whether the underwear is chosen properly or not can also depend on the shoulder straps of underwear. If the underwear is too loose or too small, the shoulder strap will slip, and this will also happen if the underwear is improperly selected.
