The Storage Pant builds a 2-layer Corded shell from 150D heavy-duty polyester, rated at 10,000mm waterproofing and 10,000g breathability, with every seam critically taped. Two cargo pockets join the hand-warming zip pockets and zip back pocket, so gear has somewhere to go beyond a jacket or a pack. YKK zippers run every pocket, and an adjustable waist pairs with cinch cuff hems to keep the fit locked in through a full day of carrying a load. What Our Gearhead(R) Experts Are Saying:"I loaded both cargo pockets with a multitool and a spare layer and never felt them swing or sag while moving fast on uneven ground. The heavier fabric shrugged off a scrape against rock that would have torn a lighter shell."
