A special breathable, rainproof and abrasion-resistant material has been added to strategic points. The NORTHWAVE EXTREME TRAIL will offer optimal protection when combined with a thermal jersey and a short-sleeved base layer, or in combination with a long-sleeved, heavier-weight base layer. This jacket is for riders on the lookout for high tech MTB apparel!
