Patagonia's Simul Alpine Pants specialize in moving swiftly and confidently over rock, snow and ice. The lightweight polyester stretch woven fabric moves, breathes and resists weather, while even stretchier fabric at the yoke and crotch gusset complement the technical cut. The waist has belt loops, a separating zip fly and our innovative OppoSet adjustable closure for an on the go customized fit. The hand, right rear and billowed right thigh pockets all close with zippers. A slender lower leg lets you see your feet, while the cuffs tighten with a shock cord and cord lock tie down loops allow you to attach an under the heel cord for use with ice boots.
