Thermarest Hyperion 32 UL Regular Sleeping Bag
The Hyperion 32 UL Regular Sleeping Bag from Thermarest is a premium 900 fill goose down bag that is ideal for camping, bikepacking and travelling as it offers fantastic warmth for its weight and is very compressible for easy packing. The down used has been treated with Nikwax, making it hydrophobic so it won’t absorb water and helping it loft up to 60 times as much as non-treated down for better insulation. Zonal distribution of the insulation, with 70% on top and 30% underneath, helps maximise the bag’s warmth whilst keeping weight and bulk as low as possible. Box wall baffles hold the down in place and prevent cold spots from forming.
All the goose down used is Responsible Down Standard Certified for peace of mind regarding the treatment of the birds and there is a large storage bag and a compression stuff sack provided with the sleeping bag.
