The Northfinder ERIN are ultralight stretchy pants for summer hikes and trekking. The elastic waistband can be further adjusted by tightening the drawstring. You will also appreciate the two front pockets as well as the pre-shaped knees. Extremely flexible four-way stretch material ensures comfort. The water-repellent treatment does not use PFC compounds ensures that raindrops and liquid dirt do not soak into the surface of the material but run down it, thus ensuring partial waterproofing of the pants and extending their life.
