About the Product
The Hyperion 32F/0C sleeping bag is among the lightest in its class while still providing high-performance during backcountry pursuits. The bag uses thermally-efficient box baffled construction in key areas to ensure warmth and comfort in an ultralight package.
For the lightest possible pack, we crafted the Vesper 45F/7C to deliver the essential warmth needed for mild-weathered pursuits. To keep it light, we used powerful 900 fill Nikwax Hydrophobic Down certified by the Responsible Down Standard.
