Technical, stretch, ultra-breathable and water-resistant, these UYN CROSSOVER SPEEDY pants are ideal for trekking in medium/low temperatures. The ergonomic structure is focused on temperature regulation and freedom of movement through the use of an exclusive knitted fabric combining Merino wool, Natex and Cordura fibres. The wool has a powerful thermoregulating effect, the bio-based yarn Natex enhances breathability while Cordura increases abrasion resistance. Ventilation is enhanced by 4-WAYS VENTILATION system integrated into the inner surface.
