Lightweight, functional t-shirt for hiking in warm conditions. Produced without PFAS. When hiking in warm climates, you want lightweight garments with maximum ventilation and this t-shirt in a quick-drying jersey knit is perfect for the job. The cut is a little looser so air can get in and cool you down, and the gussets under the arms give extra freedom of movement. The shoulder seams are positioned to minimise the risk of chafing when carrying a backpack.
