Weighing in at 630g, this Therm-a-Rest Hyperion 20F/-6C Sleeping Bag is one of the lightest most compact sleeping bags which provides peak performance in its class thanks to its Nikwax Hydrophobic Down insulation, lightweight materials and precision design ideal for uncompromising adventurers that need a warmer bag!

This is the LONG size of the Therm-a-Rest Hyperion and is suitable for people up to 6' 5", it also offers extra width too while remaining compact and lightweight making it perfect for you if you are taller or want extra space when you sleep.

The insulation used on this Therm-a-Rest Hyperion Sleeping Bag is a 900-fill Nikwax Hydrophobic Down which stays drier and maintains loft a whopping 60 times longer than untreated down, it also absorbs 90% less water and dries 3 times faster.

This has been cleverly positioned thanks to Therm-a-Rest's zoned insulation technology and by a boxed baffled construction to maximise warmth and save weight, placing 70% of the fill on the top and sides with only 30% on the back.

This sleeping bag can be integrated with Therm-a-Rest sleeping mats using their SynergyLink Connectors so you can personalise your sleep system for optimal efficiency and comfort for your chosen adventure making it an incredibly versatile cold weather sleeping bag.

We are pleased to announce that this Therm-a-Rest Hyperion 20 has won the coveted Backpacker Magazine 2019 Editor's Choice Award!
