The Momentum Pant from Prana is a classic best seller. This generous fitting, full-length stretch pant built from high quality cotton lycra with an elastic waist and an inside stash pocket. It's a natural for yoga practice or high performance climbing. Now, they've gone and made it even better by creating it in organic cotton - it feels the same (we think even better) than regular cotton, plus you get that extra good feeling because organic cotton is grown without pesticides.
