The Simms Women's Strata 330 Bottom is designed for mid-season outings where cold, wet and windy conditions call for a reliable thermal layer. The Storm Fleece Pro fabric offers a water- and wind-resistant outer face, combined with a brushed interior that retains heat during static phases. The 4-way stretch makes it possible to walk, crouch or climb without constraint, even under waders or pants with suspenders. The elasticated waistband with double snap fastener and internal drawcord ensures a stable fit on the move. YKK zipped hand pockets secure small items. Discreet leg bottoms with stirrups facilitate layering and prevent riding up under outer layers.
