Thermarest Hyperion 32 UL Small Sleeping Bag

Not only is Thermarest’s Hyperion 32 UL Small Sleeping Bag light and very compressible, but for smaller people, it will also be warmer as there is less dead air to warm up before the bag becomes effective. The 900 fill power goose down has a Nikwax treatment which prevents it from soaking up moisture; this protects the down for longer and enables it to loft much more than untreated down which adds greatly to its insulative value. The bag’s effectiveness is also increased by zoned down distribution, placing 70% of the down on top of the bag and 30% beneath it whilst the use of box wall baffles prevents cold spots from forming and holds the down in the correct place. Humane treatment of the birds used in the manufacturing process is assured by the Responsible Down Standard Certified.

Removable SynergyLink connectors enable the sleeping bag to be attached to a mattress so that the two stay together overnight and the bag doesn’t roll off onto the cold floor. A large storage sack allows the bag to retain its loft and structure when not in use and the compression stuff sack is ideal for making it as small as possible for packing into a pannier or rucksack.


  • 900 fill Nikwax Hydrophobic Down™: Stays drier and maintains loft 60 times longer than untreated down
  • Unrivalled packability: Lightweight materials and precise design allow for a smaller packed size than ever before
  • Box baffled construction: Uses mesh walls to maximise loft and minimise cold spots in key areas
  • Comfort fit: Ergonomic shape and longer zip provide a more human-friendly fit than other ultralight bags
  • SynergyLink™ connectors: Integrate the bag with a mattress for optimal efficiency and comfort; removable for versatility
  • Zoned insulation: Maximises warmth and saves weight by intentionally placing fill where it’s needed most, 70% on the top and sides with 30% on the back
  • Goose down
