The long-sleeve ActiveT-shirt is designed to be worn as the innermost layer under your hunting and leisure clothes. It is quick-drying and has been anti-odour treated. This means that it will often be enough to air the garment instead of washing it. This is very convenient if you are on a long trip with no access to washing facilities and need to pack light. This long-sleeve T-shirt has a honeycomb inner, which helps air circulation when you are exerting yourself.
