The hugely popular Precip series' Pro jacket is made with a three-layer construction. This is the most durable shell garment structure: the inner side of the outer fabric has a waterproof and breathable membrane, and a lining fabric is laminated directly onto the membrane. This provides the best possible protection for the membrane. It's recommended to wear a long-sleeved shirt underneath, but it's not necessary, for example during a summer rainthe inner surface feels more pleasant against the skin than typical 2.5-layer materials when worn over a t-shirt. This jacket is a great choice not only to bring along in case of rain, but also as a general purpose hiking jacket in cool conditions. - NanoPro Eco material: fully waterproof, fully windproof and breathable - All seams are sealed - Pit zips for ventilation - Spacious side pockets - Adjustable cuffs - Elastic hem cord - Angel Wing cut for excellent freedom of movement Center back length: 76 cm. This is a PFC-free product.
