The Women's prAna Koen Pant is a pull-on pant for all day exploring. Town, trail, wherever the adventure is happening. The nylon, polyester, and elastane blend is lightweight and breathable for moving comfortably throughout the long day. These pants stretch, wick sweat, and offer UPF 50+ sun protection, and the knit rib waistband lies softly without slipping at the waist.
