Thermarest Hyperion 20F/-6C Ultralight Down Sleeping Bag

About the ThermaRest Hyperion 20F/-6C

The Hyperion 20F/-6C sleeping bag gives you an ultralight design that’s loaded with performance-enhancing features with a temperature rating that keeps you cosy when the temps dip.

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 fibres 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.

With a pack weight of just 577g (regular), the Hyperion 20F/-6C sleeping bag has been optimised for the fast-moving adventurer looking for comfort through full 3-season camping and trekking.
