The Fjallraven Abisko Cool Shirt is a lightweight, well ventilated outdoor shirt with long sleeves. It is a regular fit that is ideal for trekking in the Spring and Summer months. Being made from Lyocell, a viscose-like fibre, it wicks away moisture while giving a soft and comfortable feel against the skin. It features two chest pockets with flaps and buttons, gussets under the arms to ensure maximum mobility, and a pair of swen ventilation holes to ensure coolness and maximum air circulation.
