Thermarest Vesper 32F/0C Down Quilt

The ThermaRest Vesper 32F / 0C is an ultralight, high-performance quilt designed for fast and light, three-season backcountry adventures. Delivering exceptional warmth-to-weight performance, it packs down incredibly small—making it ideal for minimalist backpackers and bikepackers.

Built with premium 900-fill Nikwax Hydrophobic Down™, the Vesper maintains loft longer and resists moisture in damp conditions. Its box-baffled construction maximises warmth while eliminating cold spots, ensuring efficient insulation throughout the night.

Designed to work in harmony with your sleeping mat, the Vesper reduces unnecessary bulk by removing insulation from underneath—where it’s compressed anyway. Therm-a-Rest’s SynergyLink™ connectors keep the quilt securely in place, improving warmth and comfort without restricting movement.

Thoughtful features like perimeter side baffles, a snap neck closure, and an insulated footbox help seal in heat and block out drafts, while high-quality ultralight fabrics keep overall weight to a minimum.

Whether you're heading out for a lightweight overnight or a longer alpine mission, the Vesper is built for efficient, reliable performance in the backcountry.
