I have a Therm-a-rest Vesper 20° down backpacking quilt for sale. 900-fill Nikwax Hydrophobic Down.  in perfect condition. Stored uncompressed. Undistinguishable from brand new. Selling because I never use this one (I also have the 30° vesper and sleep in my down jacket when it’s cold.)

Vesper 20° size long (21oz) $300
