Thermarest Hyperion 20 UL Regular Sleeping Bag
Description
Thermarest Hyperion 20 UL Regular Sleeping Bag Made from 900 fill Nikwax treated hydrophobic down, Thermarest’s Hyperion 20 UL Regular Sleeping Bag provides a huge amount of warmth for very little weight. The treatment means that the down doesn’t absorb moisture and lofts 60 times better than standard down for more warmth, and it is Responsible Down Standard Certified, which ensures that the birds used are humanely treated. As well as using warm, high quality down, the Hyperion has a box wall construction that holds the down in place so that it doesn’t shift and create cold spots. Thermarest has also used a differential fill process, with 70% of the down on the top half of the bag for more targeted insulation. The ergonomic shape reduces dead space within the bag so it warms up more quickly and there are removable SynergyLink connectors in place which can be used to link it to a Thermarest so that the sleeping bag remains in place overnight. A large storage sack is included that keeps the bag well lofted in storage whilst the compression sack helps when it needs packing away into a rucksack or pannier.
