What is the Therm-a-Rest Vesper 32F/0C Regular Quilt?
The Vesper is Therm-a-Rest's ultralight performance quilt, designed for hikers and adventurers who prioritise speed, efficiency, and pack space in the backcountry. Using premium down insulation, featherlight fabrics, and a modular design, it balances comfort and adaptability at a fraction of the weight of a traditional sleeping bag. Perfect for summer backpacking, thru-hikes, bikepacking trips, and lightweight alpine missions, the Vesper 32F/0C keeps weight low without sacrificing essential warmth.
What is it made of?
Insulation
The Vesper is filled with premium 900-fill Responsible Down Standard (RDS)-certified goose down. Exceptionally light and warm, this down offers one of the best warmth-to-weight ratios available. The clusters are treated with a PFAS-free hydrophobic finish, enabling them to resist moisture, dry faster, and retain loft in damp conditions. With such a high fill power, the quilt achieves outstanding compressibility, packing down to a minimalist size without compromising insulation.
RDS certification guarantees ethical sourcing, ensuring that the geese are never force-fed or live-plucked and that strict animal welfare standards are met throughout the supply chain.
Shell and Lining
Encasing the down is a 10-denier nylon ripstop shell — remarkably lightweight yet engineered for durability. The ripstop weave prevents snags or abrasions from forming or expanding into larger tears, helping preserve the quilt's longevity in rugged environments. The PFAS-free Durable Water Repellent (DWR) finish sheds light moisture such as dew or condensation without relying on harmful chemical treatments.
Inside, the soft nylon lining feels smooth against the skin and stands up well to repeated packing and use, contributing to the overall featherlight packability and durability of the quilt.
What are its features?
Box-Baffled Construction
The Vesper employs box-baffled construction to maximise down loft and eliminate cold spots. Full-perimeter side baffles and a draw-cord neck closure work together to seal out drafts, keeping warmth securely inside during cooler nights.
SynergyLink Connector
The quilt includes Therm-a-Rest's removable SynergyLink connector, which attaches the quilt to your sleeping pad to reduce side drafts, prevent slipping, and enhance thermal efficiency. For warmer conditions, the connector can be removed, letting the quilt function more like a blanket.
Packability and Weight
Thanks to ultralight down and minimalistic materials, the Vesper compresses into an impressively compact size. The included stuff sack packs to just 14 × 20 cm (5.5 × 8 in), making it easy to stow even in small-volume ultralight packs. Despite its compact form, the quilt delivers dependable insulation down to 0°C (32°F).
Temperature Ratings
Independently tested to EN standards, the quilt provides a comfort rating of 5°C (41°F) for average sleepers and a lower limit of 0°C (32°F). This makes it ideal for summer trips and warmer shoulder-season outings where low weight and high packability are essential.
