The Therm-a-Rest Vesper Quilt replaces our bulkier, heavier sleeping bags on minimalist-minded, summery backpacking trips. It weighs a little less than a pound, and can pack down to the size of a water bottle. Therm-a-Rest used down insulation with the highest rill rating (900) to ensure the loftiest warmth and the smallest compressibility. This down also boasts a Nikwax hydrophobic treatment to retain its lofty warmth in moisture-riddled environments.
