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.
UL: Ultralight. Pertex® Endurance® 10 denier water-resistant/breathable fabric.
Best Uses: Ultralight Backpacking, Alpinism, Emergency Bivy
"For those who have their sights on first ascents, ultralight pursuits, or savings in weight and bulk with respect for RDS certified down, the top-shelf 900-plus* fill Vireo could be your ticket."
