Men's thermal underwear Columbia MIDWEIGHT STRETCH LS TOP check comfort is determined by the layer of clothing closest to the skin. There is no room for experimentation here. Developed in cooperation with the best physiologists, the Base Layer underwear from Columbia is maximally warm and perfectly light, and its action varies depending on the body zones, ensuring optimal comfort. See the rich offer, we present a wide range of interesting models in many colors, such as Columbia men's underwear. You will definitely find something for yourself At a temperature of approx. -10/-13 degrees Celsius, such technology works great. Comfort is also complemented by the appropriate type of material used, so that after training you do not feel an unpleasant smell.      Innovative design based on the body map maintains heat and wicks away moisture, thanks to the use of heat-reflecting Omni-Heat® points in the zones that need it most, and moisture-wicking Omni-Wick™ technology in places most susceptible to sweating. An antibacterial treatment ensures the material looks (and smells) fresh even during intense exercise, while a zip helps regulate body temperature when needed. This mid-weight top is your key to success—it’s super stretchy, has flatlock seams to prevent chafing, and raglan sleeves for even more freedom of movement.Why Columbia MIDWEIGHT STRETCH LS TOP men's thermal underwear:   Fabric: 86% polyester / 14% elastane   Omni-Heat heat reflective technology,   Omni-Wick advanced evaporation technology,   Perfect fit,   Antibacterial properties,   Comfortable, four-way elasticity,   Ergonomic seams,   Thumb holes,   Manufacturer: Columbia Sportswear, USA Care instructions: machine wash at 30° C   Omni Heat Thermal Reflective - helps regulate temperature by reflecting and retaining body heat, while allowing moisture to escape, which helps maintain a sense of comfort. The inspiration for creating Thermal Reflective materials were the extraordinary properties of rescue, aluminum thermal blankets. This innovative technology provides 20% more thermal insulation, while maintaining a high level of air and moisture permeability. Omni-Wick® is a new technology for sending moisture away from the body to the outside. Products with Omni-Wick® perfectly absorb moisture and sweat and then quickly transport it away from the skin, where it quickly evaporates. This process means that the user always has cool and dry clothing. When running at a temperature of approx. -10/-13 degrees Celsius, this technology worked great. However, due to the cold, I also put on a windproof jacket over the sweatshirt. Importantly, in my opinion, due to its properties, Omni-Heat technology is the optimal choice for such frosty/possibly cold days, at positive temperatures we may already be too warm in such underwear. The feeling of freshness was very important after finishing the run. During intensive effort, there is no feeling of sweating, which is due to the Omni-Wick® technology, which consists in dispersing the sweat produced during effort and wicking it away, and then evaporating. The comfort is also complemented by the appropriate type of material used, so that there is no unpleasant smell after training. Advantages: great thermal insulation thanks to the use of Omni-Heat Thermal Reflective optimal comfort of use at minus temperatures ergonomic cut (adaptation to the body) very well profiled sleeves adapted to cover the wrists low weight no unpleasant smell after training Guarantee of product originality: All products from the polstor.pl offer are original and come directly from the manufacturer Columbia Sportswear Company If the above description is not sufficient for you, send us your question about this product.
