In the high alpine, you need a hard shell that can withstand brutal, wet, windy weather with constantly changing temps. You also need a shell that can breathe when you're working hard uphill. But the trick is, you don't want to carry along the weight and bulk of two different jackets.

Enter the Microgravity AscentShell Jacket: The solution to your crazy-weather yet crazy-exertion alpine adventures. With such stellar breathability and every feature you'd need to be comfortable in the mountains, you'll never have to compromise on protection again.

Since 2016, Outdoor Research's proprietary AscentShell™ technology uses an electrospun process to create a 3L construction that breathes faster, weighs less, stretches more, and far surpasses the comfort of traditional waterproof membranes.
