Ultralight down bag for high-performance warmth

Going fast and light on the trail or in the hills means shaving every possible gram without sacrificing vital functionality. The Hyperion 20°F/-6°C is among the lightest sleeping bags in its class, designed to cope with 2-3 season conditions without sacrificing performance. But when packed down into its compression stuff sack, it is impressively compact, allowing you to carry it with ease, even in a small rucksack. It’s designed to work with an insulated sleeping mat to keep you warm, with zoned fill that strategically places more of the premium 900 fill-power down on the top and sides of your body, leaving your mat to do its job underneath. It’s also fitted with removable SynergyLink connectors – basically, thin elasticated straps that keep your bag attached to your mat (no more sliding around in the night). But plenty of attention has also been paid to comfort too, with super soft fabrics, an ergonomic shape and a longer zipper to give you a better night’s sleep compared to the highly tapered ‘performance mummy’ fit of most cramped ultralight bags
