Thermarest Hyperion 32 UL Large Sleeping Bag

Thermarest’s Hyperion 32 UL Large Sleeping Bag offers 13cm more length than the standard version, along with some extra width too, so larger people can enjoy more space and comfort when camping. It is constructed with a box wall design to keep the 900 fill Nikwax Hydrophobic Down in place without creating any cold spots, and zonal distribution designed to provide more insulation where it is needed most. The water-resistant treatment on the down prevents it from soaking up moisture, allowing it to loft up to 60 times more than untreated down, thus providing far better insulation. All the down used is Responsible Down Standard Certified, meaning that all the birds used have been humanely treated.

Removable SynergyLink connectors can be used to attach the bag to a Thermarest sleeping mat, ensuring that they remain together throughout the night and there is a compression stuff sack and storage bag included.


  • 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
