Breathable, Rugged Weather Protection For Alpine Adventures Serious objectives require serious protection and comfort. Enter the MicroGravity AscentShell™ Jacket is a dynamic, breathable, waterproof shell for alpine climbing, backcountry skiing, and any adventure above the tree line. The patented AscentShell™ membrane is laminated to a stretchy knit backer for waterproof mobility, and fully taped seams make this jacket impervious to wind and water. YKK® Aquaguard® zippers seal out the elements, while underarm gussets and a halo-hood with Hood Lock™ allow a full range of motion, a custom fit, and protection from the elements. A left-hand pocket doubles as a stuff sack, and a key clip ensures you a ride home. This MicroGravity AscentShell™ is technology-packed with intuitive features to keep the focus on the objective at hand, not on your gear.
