The Mountain Hardwear Warp Factor Bib brings a lighter, more natural drape to full storm protection. DrySpell 2-layer waterproof fabric blocks moisture through real storm cycles while staying breathable, woven into a ripstop that moves quieter and more like a densely woven textile than a typical stiff shell. CORDURA reinforcement at the knees and hem adds durability for seasons of hard-charging laps, while body-mapped ThermoCloud insulation at the seat and knees adds warmth exactly where it's needed on the lift or kneeling in snow. What Our Gearhead(R) Experts Are Saying:"I wore this through a full storm cycle and never felt the clammy buildup I get from a stiffer shell. It moves with me on the chair without ever feeling like I'm wearing a tent."
