Patagonia has earned a reputation for durable outerwear that will last for years, even in the most abusive relationships. So, when Patagonia calls a pant its 'most bombproof,' you know it can hold up to some serious hardship. That's the claim that Patagonia made for its Primo Pant. From its super-tough recycled nylon main body fabric to its 3-layer Gore Tex laminate, you know the Primo will be around for a while. And, as always, Gore Tex means guaranteed waterproof and guaranteed breathable, so you can handle anything that nature throws your way without feeling moist and clammy. Patagonia didn't hold back when it designed the Primo pant. Gore-Tex 3-Layer represents the absolute best that the industry has to offer. The main body fabric is recycled nylon--known for its durability. Tough, reinforced kick patches at the ankles fight off attacks by sharp ski edges, so your cuffs won't fill up with snow after a run in the deep stuff. The Untracked pant's fit is Progressive, which is Patagonia-speak for loose. The highly articulated fit moves with you while you hike or ski and feels comfortable and natural, and the articulated knees and gusseted crotch add to this feel. Zippered thigh vents make it easy to dump heat when you need to. Patagonia finished the pant off with a Recco reflector, which aids in search and rescue should you become involved in an in-bounds avalanche.
