R1 Air Vest delivers breathable warmth and stretch for active alpine layering
What Our Gearhead® Experts Are Saying:
"I wear the R1 Air Vest as my go-to core layer when I'm moving fast in cool alpine temps. It's insanely light, packs down tiny, and vents heat well thanks to the hybrid design. The fit is trim without being restrictive, and it layers cleanly under a shell. Plus, it doesn’t hold onto odors, even on multi-day outings."
When we’re pushing toward summits or logging fast miles on cool ridgelines, the Patagonia R1 Air Vest is the core warmth layer we trust to keep us comfortable without overheating. Lightweight, stretchy, and breathable, this hybrid fleece vest keeps our torso warm while letting excess heat escape where it matters most—under the arms and across the back.
Built from a blend of Polartec® Power Grid® fleece and Capilene® Thermal Weight fabric, the R1 Air Vest balances insulation with airflow, allowing us to regulate body heat during high-output missions. The fit is low-profile and layering-friendly, while HeiQ® Pure odor control means it stays fresh between washes. With a minimalist design and zippered chest pocket, it’s our secret weapon for ultralight layering and fast-moving alpine objectives.
