What Our Gearhead(R) Experts Are Saying: "I took the Guardian Air Jacket on a high-alpine multi-day trip, and it crushed it. It's lighter than anything else I've worn with full waterproof protection. I barely noticed it in my pack-until the storm hit and I was glad I had it."The Guardian Air Jacket from 7mesh is our go-to for serious backcountry missions where weight matters, but compromise isn't an option. Designed with GORE-TEX's new ultralight ePE membrane and a featherweight 15-denier ripstop face, this is one of the lightest fully featured rain shells on the market. And it's built to keep up with the most demanding days in the mountains. We love how the refined articulation improves range of motion on climbs and descents, while the helmet-compatible CrossPull Hood and glove-friendly adjustments help us adapt to fast-changing weather. A high-coverage collar and clever Stowaway Snap keep the hood secure when the wind dies down, and the internal StashSystem pocket keeps essentials close. Whether we're pushing ridgelines or covering miles of unknown singletrack, the Guardian Air Jacket is a minimalist masterpiece that performs far beyond its weight class.
