Vesper Quilt

The Therm-a-Rest Vesper Quilt replaces your 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. In wet places that would usually crinkle the down until you're cold, this quilt's down has the potential to stay warm and comfy in humid, rainy weather. As if that wasn't enough, Therm-a-Rest added a ThermaCapture lining to reflect your own body heat for even better warmth. SynergyLink connectors keep your sleeping pad underneath you so you don't slip onto the tent's floor at night, and the snap neck closure works with the insulated footbox and perimeter side baffles to make sure you stay in the quilt and drafts can't go in.

Loved it. Best nights of sleep I've ever had in the Sierra's. Spent four nights in the Kings Canyon area in late June. We had relatively warm nights, except for the night we spent at about 10,500'. Even that night I just layered clothing and slept like a baby. I turn a lot and side sleep and loved how the quilt stayed on me, but allowed me to spread out, move around, roll over etc. Coldest night was maybe 30-35. Warm nights in the 50's and I slept in a t-shirt. The bag packs super light, and very small. Just a little bigger than a standard Nalgene bottle.
