Don't worry though, we have a lot more Synthetic Sleeping Bags in stock than that.
Shop Similar ProductsWhy We Built The Groundwork Double Sleeping Bag
We made the Stoic Groundwork Double Sleeping Bag because it's challenging enough to find a sleeping bag for two, and it's even harder to find a bag that feels comfy in colder and warmer temperatures. This double-wide sleeping bag offers soft warmth even when the forecast calls for gray skies and morning fog. You're welcome to cozy up with your partner, or unzip the bag into separate parts in case someone heads out on a solo mission.

Arkansas backcountry 30 degrees and?
- Familiarity:
- I've used it several times

We just came back from a back country trip in central Arkansas, on our last night it got down to around 30. We even had a heater running in our tent and a dog in each bag with us and we froze. Dogs were shivering. Rough night. No way this is a 20 degree bag. Totally inaccurate. Down right dangerous if you laid on the ground in 20 degree temps in this bag.

New Favorite
- Familiarity:
- I've used it once or twice and have initial impressions
I havent camped down to 20, but did do a dry run with this sleeping bag down to 30f in a tent and it was 10/10. We could move freely and its pretty roomy IMO. It also packs down pretty small, its definitely smaller than my last 1 person sleeping bag. When I need another sleeping bag, I’ll definitely be checking out Stoic first

Best for summer camping

For the price, not a bag double bag. Nice that you can unzip into two separate bags. Will be perfect for summer camping but the 20° rating is totally inaccurate. Used this bag with my husband in late October in Oregon and we would have froze if we didn’t have zero degree bags with us. I was wearing multiple layers including wool base layers and wool socks, had our husky pup on top of the bag with us for extra warmth, the low got down to about 30° and we were still pretty chilled.

A sleeping bag that doesn't zip up...
- Familiarity:
- I've used it several times
- Size Bought:
- NA
Total junk, snags multiple times while trying to zip. Poorly designed for a sleeping bag style that's as basic as it comes and been around a bit. Somehow they still got it wrong. Backcountry should not be selling the this garbage..

Good trailhead camping bag
- Familiarity:
- I've used it several times
- Weight:
- 185
This bag is a nice economical alternative to a down sleeping bag if you are only going to be trailhead camping. I am not sure it is 20F though, I think 30F would be a more fair rating.

No way this is rated to 20F
- Familiarity:
- I returned this product before using it
Even unzipped and with the two bags doubled up there's no way this would get through a 40F night. Returning.
Do you have a question about this product?
March 12, 2021
Is this coated with any flame retardants or harmful chemicals?
March 4, 2021
How is the comfort in cold temps? I know this is subjective but is 20 F the comfort or extreme temperature rating?
October 15, 2020
2nd the question about the dimensions as its laid out flat.
September 18, 2020
What are the dimensions of the bag (laying out flat)? I see the shoulder circumference (166in) which seems much wider than most double bags. Thanks!
