LAPASA Heatgen Generation Thermal Underwear Sports & Fitness and Cycling Review

45% Acrylic, 30% Rayon, 20% Polyester, 5% Spandex. Pull On closure. 【HEATGEN FABRIC】HeatGen fabric keeps you warmer longer and faster. The body's own moisture is converted into heat. 【OPTIONS】M84 - Crew Neck 150g/m2 Midweight for cold weather; M104 - Turtleneck 150g/m2 Midweight for cold weather. 【SUPER LIGHTWEIGHT】This base layer top is ultra-lightweight, but gives you the warmth you need without the thickness or weight of traditional bulky materials. 【LOW KEY COMFORT】This thermal top is invisible under other clothing and will not bulge. It's the perfect comfortable garment for the colder months, whether you're playing outdoors, sleeping, at home or in ski and snowboard clothing. 【FLEXIBLE AND ELASTIC】This warm top fits snugly and does not restrict freedom of movement. Tight fit and double elastic cuffs reduce heat loss.
