Groundwork Double Sleeping Bag: 20F Synthetic

Why 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.

This is the best sleeping bag for two! It is very light and comfy and surprisingly very warm!

Good trailhead camping bag
- Familiarity:
- I've used it several times
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

Even unzipped and with the two bags doubled up there's no way this would get through a 40F night. Returning.

Just OK

Pros: it is a double sleeping bag for a decent price, and my wife likes it. Cons: it’s definitely a Summer bag only. The 20°F rating is ridiculous. The color also looks more washed out than the photos (I got the oatmeal), and feels… cheap. Summary: my wife likes it so we will keep it… but curb your enthusiasm.

Cute and cozy

It’s a lovely way to make camping more cozy and intimate! It was a little chilly for spring camping, but my girlfriend loves to cuddle (as do I) and I appreciated the functionality of a two person sleeping bag :)

Do a gear check before you use it

I like to sprawl out and I run warm so this bag is great for what i need. If you camp below 50F think about wearing some base layers and socks to ensure you keep warm. Now the one bad thing. The compression sack. I hope this is just an oversight and not indicative of overall quality. But i tried to cinch down one of the straps and the quick release buckle just gave up. I tried buckling it again to see if it just worked loose in transit. Nope it slips with any snug pull. Then checking the strap i noticed it was sewn in backwards. With the pull strap end out the strap twists. So not only did they mess up in assembly of this part of the strap but the components were defective. I did try to cinch the other strap to see if both are poor quality but the other one held, barely. The snap buckles are undersized. So if you must compress down the bag then test these first thing. If you don’t need to shrink it then don’t worry if this happens as the stuff sack is fine. Customer support was very nice and quick and offered to send a whole replacement. I don’t need the compression so i will just fix the buckles myself. Just check your gear before you use it. You never know if. The person assembling your gear was feeling sleepy for that one product.

It's a sleeping bag!

Bought this double bag for my wife and I to replace a lower quality one we had. Haven't been able to take it camping yet, but it did get some use sleeping in the hallway with the kids during the hurricane. It's definitely an upgrade over what we had. Lighter weight, better construction, packs better, and more comfortable. Stuff sack has lots of straps to cinch it down. It's pretty slippery though, which my wife is on the fence about (the reason for deducting a star).

Nice Summer bag, for 50+ degrees?
- Familiarity:
- I returned this product before using it
Nice bag, but it is definitely not a 20 degree bag - - see other reviews. Out flat, it is definitely thinner than my 40 degree bag. Even 4 layers of this bag are still thinner than my 20 degree mummy bag. My best estimate would be no colder than 50 degrees and likely better at even warmer temperatures. See other reviews for the additional insulation needed in order to reach lower temperatures.

Incredible Comfort and Warmth

For full disclosure, we used this bag during a car camping trip. We slept in a tent on the ground but had several layers under us. My setup is not at all possible for backpacking. But for this use it was fantastic and we will definitely use this again. This was my sleep setup: Big Agnes Aircore mats (uninsulated) > A regular old full size quilt > A faux down comforter > Stoic Groundwork Double Sleeping Bag > Basecamp Bivy Quilt I slept with leggings, hiking socks, T-shirt and hoodie. The temperature was around 38-40 at night with a little bit of rain. I was so warm and so comfortable. There were a couple nights I unzipped the bag and stripped some layers off. I think it is possible we could have been warm without all the insulating layers under us, but we had room for the extra blankets and we wanted to be super comfy. We both agreed these were far superior to a set of flannel lined Teton bags we used on our last trip. It seemed like we warmed up way faster and stayed warm throughout the night. I also really liked how easy you can slide in and out of the bag on the fabric. One minor complaint: It is very easy to catch the fabric in the zipper. You need to pay attention to what you're doing as you zip and unzip it. I am 5'6". My husband is 5'11". We both had plenty of room in this bag.
