Coleman Big Bay 20° Mummy Sleeping Bag Review

That’s not always feasible when camping, but sleeping in a clean base layer or pajamas increases your bag’s longevity. During a warmth test we conducted during a very chilly evening in Bryce Canyon National Park, we were shocked to find that the Brazos held its own when it came to insulating. For the extensive sleeping bag review, I also interviewed experts who could speak to what makes a great sleeping bag and how to choose the right one for your needs. I talked to an assistant professor at New York’s Fashion Institute of Technology (FIT), Preeti Arya, who’s an expert in technical fabrics and sustainability. I also spoke with Jeremy Cronon, the expedition equipment lead and outfitting manager at NOLS (National Outdoor Leadership School) Rocky Mountain, and Austin Robbs, director of equipment and accessories at Patagonia.

And if the bag has a tough exterior shell, you can use it as an outdoor picnic blanket in a pinch. Some bags, like The North Face’s One Bag, feature unique warmth-tailoring systems that allow you to customize the amount of insulation depending on conditions. To be sure, most of these additions won’t be deal-breakers for many, but they can be helpful in deciding between similar models (and we’ve called them out in the write-ups above whenever possible). Anyone have any experience wit coleman chairs, as a budget option? We don’t camp a lot, but we live in CA, so being forced from our home is always in the back of our mind (earthquake, fire, etc). When it comes to packed size, the Brazos lands right in the middle out of all of the bags we tested.

We also scored each bag on how easy it rolled up and fit into its storage bag. It rolls up easily and fits into its stuff sack with a little bit of effort. It’s also quite a stretch, but it could double as a backpacking bag if you’re in a pinch.

It works well for camping trips, offering cozy warmth without adding a lot of weight. This sleeping bag has a memory foam bottom, which adds an extra layer of comfort between you and the cold ground. Mummy bags are popular for both camping and backpacking, but rectangular bags are roomier and can offer an even better sleeping experience.

That being said, we feel they are still a great choice for young kids (who sleep through most anything) or teens (who don’t sleep and will most likely be around the campfire all night). We don’t suggest the Brazos for colder weather, however, for normal late Spring and Summer camping, this bag will hold its own when it comes to keeping you warm… as long as you can fit in it. The Coleman Sacks jacket is made from a Vintage Coleman sleeping bag or similar vintage bag. This jacket has an oversized bomber jacket fit with meticulous craftsmanship.

Notable extras worth calling out are built-in pillows or pillow sleeves (the Nemo Disco and Forte Endless Promise boast the latter), which are a nice luxury for those annoyed by camp pillows that tend to move in the night. Additionally, integrated blankets, interior pockets for stowing small items like a headlamp, and draft tubes at the collar for trapping warmth are becoming more coleman sleeping bag common. Mummy bags typically have a ¾-length side zip that requires some wriggling to get in and out of and can’t be opened up completely should you want to zip the sleeping bag together with another compatible bag. Not only is it easy to create a large and comfortable space for two if you zip it to another bag, but unzipping the bag on its own opens it up for use as a blanket.

In terms of dimensions, they’re typically roomier than standard mummy bags (particularly at the shoulders and hips) but not overly generous like some rectangular models. All in all, semi-rectangular bags typically offer a good mix of comfort and weight, shaving away excess material while still providing enough space to roll around during the night. For instance, Nemo’s Disco 15 and Forte Endless Promise 20 have roomier fits than most traditional mummy bags, with a noticeable boost in space around the knees and elbows. Kelty’s popular Cosmic Down 20 has been a mainstay in their lineup for years and remains a popular choice among campers and backpackers alike. For starters, you get a respectable weight of 2 pounds 10 ounces, which is the lightest three-season option on our list (Kelty’s own Galactic 30 below weighs around the same but is far less versatile).
