Thermarest Hyperion 32F/0C Ultralight Down Sleeping Bag

About the ThermaRest Hyperion 32F/0C

The Hyperion 32F/0C sleeping bag gives you an ultralight design that’s loaded with performance-enhancing features.

Crafted for the outdoor minimalist, the Hyperion features an Ultralight Fit, streamlined to a narrow silhouette for a weight-saving design and unrivalled packability. Zoned insulation saves weight by placing down fill in key areas for an optimum warmth-to-weight ratio while a 10D nylon ripstop liner and DWR shell keep the pack weight low.

A 900 fill Nikwax Hydrophobic Down continues to insulate even when damp while maintaining loft 60 times longer than untreated down and drying 3 x faster – all without the use of PFCs. A Responsible Down Standard certification ensures all down fibers are sourced humanely.

SynergyLink™ Connectors on the bag’s underside let you integrate the Hyperion with a sleeping pad to create a complete all-weather sleep system. This is great for added warmth and to ensure the mattress remains beneath you – especially in colder climes. Pad connectors can be removed for convenience.

The Hyperion also features a cinchable hood, heat-trapping draft collar and zipper baffle for maximum heat retention with a snag-free zip for hassle-free access.

When it comes to the outdoors, the Hyperion 32F/0C gives you a high-performance sleeping bag that’s crafted to see you through 3-season adventures. With a pack weight of just 520g (long), this bag has been optimised for the fast-moving trekker who refuses to compromise on comfort.
