Seamless functional thermal underwear has an anatomical cut with compression zones. Functional polypropylene fibers quickly wick excess moisture away from the body without absorbing it. At the same time, the underwear uses the "body mapping" technique, so it uses different knitting strengths on different parts of the body. The smooth seamless design has an undeniable advantage in wearing comfort and zero risk of possible abrasions. The T-shirt has only two seams in raglan-set sleeves, but you won't feel them on your skin thanks to the technology of external seam stitching. The bottom hem and sleeve ends smoothly transition into a stretchy ribbed knit that adapts well to the body. The T-shirt is made of a lower weight, so it is suitable for aerobic activities such as ski mountaineering, cross-country skiing or snowshoeing.
