Therm-a-Rest Vesper Quilt 20
Light and warm, this Therm-a-Rest quilt saves space in your pack—and keeps you comfy at camp. The warm 900-fill-power down is ideal for serious fast-and-light adventures.



- Provides the no-frills, high-performance camp comfort you need for serious fast-and-light adventures
- For comfort, use in temperatures down to 32°F; recommended lower limit is 20°F, but everyone's body and sleep comfort differ, so these are simply guidelines
- Designed with high-quality, PFAS-free materials
- Thermally efficient box baffled construction and premium 900-fill-power down insulation maximize heat retention at an ultralight weight
- Lightweight 900-fill-power down and precise design allow for a sensationally small packed size
- 900-fill-power hydrophobic down is incredibly light, compact and warm, and it is PFC-free
- Responsible Down Standard (RDS) certified down; RDS certification ensures that the waterfowl in the down supply chain are treated humanely
- Box baffled construction uses mesh walls to maximize down loft and minimize cold spots
- SynergyLink™ connectors: Removable ultralight straps create a secure bag-to-sleeping pad connection that optimizes the comfort and thermal efficiency of your sleep system
- SynergyLink™ Connectors function best with a regular-size sleeping pad (not included) that is 3 in. thick or less when inflated
- Perimeter side baffles, snap neck closure and insulated footbox eliminate unwanted drafts
- Storage sack and compression stuff sack included
Imported.

Great Quilt to Purchase
The quilt after using it on the PCT is exactly what is advertised. I have it over top of Therm-o-rest mattress and you will never get cold at night up in the desert. Have not made it yet to the mountains to test it there. Temperatures at night in the desert are getting below 32 F.
I've used it twice now.
I've used it twice now. It performed very well in mid- to low-30 F temperatures. I'm very happy!
