The long-sleeve Härkila Base Active undershirt is warm and quick-drying, and excels as a base layer for active hunting and outdoor leisure activities, whether it’s just cool outside or genuinely cold. The long-sleeve Härkila Base Active undershirt is made from a hi-stretch, quick-drying blend of 94% polyamide and 6% elastane. The fabric has also been Polygiene®-treated to prevent odours and bacterial growth. This means it doesn’t need washing so frequently, can be washed at lower temperatures and will last longer, all of which helps protect the environment. As well as being quick-drying, the undershirt also has extra-breathable zones at the collar, on the shoulders, under the arms and on the forearms. This makes it comfortable to wear, even during high exertion. The undershirt has an active, snug fit.
