About the Product
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.
Built to provide a featherlight pack weight and high-performance warmth, the Hyperion 20F/-6C is among the lightest in its class without sacrificing an ounce of performance.
