About Base Layer Tops and Bottoms
They have exceptional warmth and softness because a light weight yarn is thoroughly brushed both inside and out.
Ultimate freedom of movement and fit is provided by an innovative knitting technology that creates a multi-directional stretch.
Meticulously done flat seams reduce bulk, creating a comfortable non chafe fit, which is ideal for layering.
You stay drier and fresher thanks to an amazing moisture and odor management technology.
They are made of 84% polyester and 16% elastane and are machine washable.
About Thermal Tights and Leggings
They are made from an advanced insulating yarn. Thanks a soft-brushed inner pile, the amount of warm air held close to the skin is absolutely maximized. This means high performance insulation.
Both tights and leggings have built-in stretch, with an elasticated waistband and a comfort gusset panel to improve fit and add comfort for all-day wear.
They are made of 91% polyester and 9% elastane and are machine washable.
All this means you can trust them to keep you cozy! If your legs have always been cold in the winter, now they will stay much warmer. You don’t need to spend your winter in bed keeping your legs warm! Now you can walk outside and not freeze your legs off.
Don’t let winter ruin your days. Whether you are going to the hills, to the office or just going for a quick grocery shopping on a frizzy day, this thermal underwear provides insulation and warmth.
It sits well under your clothing without adding bulk and disrupting your style. Equally important, it allows full mobility.
