New for Winter 2025/2026: The Vireo UL gets all-new Pertex® Quantum Pro® shell fabric + Pertex® Diamond Fuse lining fabric in the footbox, plus new and familiar colors
The Vireo was designed with a single purpose in mind; fast and light alpine climbs where every gram counts. With no hood, no zipper and a variable fill (the lower half is rated at 25ºF / -4ºC, the upper half 45ºF / 7ºC) the Vireo shaves every last ounce. For maximum efficiency and warmth, pair the bag with a down jacket to not only keep you cozy but also minimize extra gear and weight when it matters most.

Best Uses: Ultralight Backpacking, Alpinism, Emergency Bivy
Best for Moving Fast and Light
