The optimal underwear in wool mix for training at moderate intensity in all weather conditions. Active Wool is perfected for varied weather, as the Merino Wool/Tencel ™ mixture effectively regulates your core temperature, so you are well insulated when cold and cooled down when it is hot. This mixture extends the shelf life of the garment and provides all the qualities that wool gives you, so it absorbs an impressive amount of moisture and safeguards breathing capacity. Tencel ™ reinforces the wool's already effective moisture transport during both activity and rest, so you stay dry throughout your session. Since we stretch to create products with reduced environmental footprints, Active Wool is so-called non-Dye super underwear, which means that the production of Active Wool saves 3.5 liters of water per garment, so you get underwear with lower environmental footprints. The flatlock seams ensure reduced rubbing. This long -sleeved top is optimal when making maximum potential without compromising comfort, regardless of the season.
