Even the top speed climbers have shivering-on-a-Iedge tales of misery. But the wise - and those who have learned the hard way - opt to bring a modicum of high-loft warmth. Our lightweight Micro Puffs are shelled with windproof and water-repellent ripstop polyester and use super-efficient Polarguard Delta insulation that won't wilt in wet conditions and compresses tight in a pack. The vest has a snap placket and an inside chest pocket that doubles as a stuff sack with a clip-in loop. The pullover features a water-repellent main zipper that's deep enough to pull on over a helmet and a hidden-zipper chest pocket; it comes with a water-resistant stuff sack. Pant features: fully separating, two-way side zips; a zip fly; reinforced seat and knees; and elasticized cuffs. All are sized to wear over layers. Imported. Micro Puff Vest (Unisex)
