    • Great sleeping bag from a great brand that works well.
Size: PFAS-Free Style: 20?f Big & Tall
A Cozy and Reliable Companion for Chilly Nights Finding the right sleeping bag often involves balancing warmth, comfort, and price. The Coleman Big Bay 20°F Mummy Sleeping Bag manages to hit the sweet spot on all three, delivering a high-quality experience you'd expect from a trusted brand like Coleman. After testing it out, I've been thoroughly impressed by its thoughtful design and cozy feel. Why It's a Great Choice Excellent Construction & Zippers: Right away, you can feel the quality in the materials. The stitching is robust, and the zippers are a standout feature. They glide smoothly without snagging, which is a huge relief when you're trying to zip up in the dark or get out of the bag in a hurry. Toasty Footbox: One of the best features is the footbox. Coleman added an additional layer of soft, plush material right where you need it most. This does an amazing job of keeping your feet warm and comfortable throughout the night, preventing those cold spots that can wake you up. Stylish Color Scheme: While performance is key, it doesn't hurt that the sleeping bag looks great. The color combination is modern and appealing, giving it a premium look that stands out from more basic, single-color bags. Comfortable and Versatile Inner Lining: The soft inner material is fantastic. When you first get in, it feels cool and pleasant against your skin. As you settle in and zip up, it quickly traps body heat, providing excellent warmth and insulation against the cold. Easy to Clean: This is a huge practical benefit. The sleeping bag is designed to be washed in a standard-sized home washing machine. This makes cleanup after a camping trip incredibly simple and convenient, saving you a trip to the laundromat. Outstanding Value from a Reputable Brand: With Coleman, you know you're getting a product backed by years of experience. The Big Bay sleeping bag offers features and comfort often found in more expensive models, making it a solid value and a reliable investment for casual campers and outdoor enthusiasts alike. Final Thoughts The Coleman Big Bay 20°F Sleeping Bag is a fantastic option for anyone looking for a dependable, comfortable, and well-designed sleeping solution for cool-weather camping. Its user-friendly features, from the snag-free zippers to the machine-washable convenience, make it a standout product. It delivers on its promise of warmth and comfort, all while being an excellent value. ... show more

    • Fantastic Sleeping Bag
Size: PFAS-Free Style: 20?f Big & Tall
I finally had the opportunity to bust this thing out two weekends ago while camping in the mountains where it was much colder than normal, and this thing did not disappoint. I could not believe how big it was after I got it out of the bag and unrolled it, and it is a great size. It's not very heavy at all considering the size of it, and after it was rolled out it kind of puffed up and was super comfortable and very warm. It's an excellent quality sleeping bag, and kept me warm all night. The zippers work great, and I love the fact that you can unzip it at the bottom if your feet get too warm. This is hands down my new favorite sleeping bag! ... show more

I was on the fence about this sleeping bag when I ordered it but I was pleasantly surprised when it arrived. The color looks as cool as advertised and it feels pretty svelte. Because the material is all polyester it does retain heat the way polyester does so even though it's thin (and I have so far only used it when it was about a low of 40 degrees), I would not be surprised if it would be comfortable in even lower temperatures (though your experience might vary). The bag looks well-constructed (thought I saw a number of dangling threads (i.e., maybe not the best quality control at the end), and the bag was comfortable. I like the zipper cover and the sewn-in cell internal cell phone velcro-tabbed cell phone pocket (see pic). I'll also note that it's very big - I am over six foot tall and it fit me with height to spare and a ton of width to spare. I liked that it had a zipper at the bottom so you could open it up at the foot of the bag (in case your feet get warm) though I've seen other bags that had both a zipper and mesh at the bottom - a zipper to let the heat escape and mesh to prevent any bugs or critters from climbing in. The sleeping bag came with its own carrying bag (see pic) which I liked as I feel like I could easily clip the packed sleeping bag to my hiking backpack and take it with me. With that said, it was a bit of a pain to get the sleeping bag back into its bag - I had to fold and refold it and do my best to squish out all the air. Maybe I'll get better with more practice. Then again, I've had similar problems with other sleeping bags - so maybe it's user error on my part or maybe it's a common design issue. With all the above in mind, I still enjoy the bag a lot and look forward to using it more! ... show more

    • Great for just my husband
Size: PFAS-Free Style: 20?f Big & Tall
There's no way 2 people can fit in this unless they are sticks. Normal people, it's one person per camping bag. That being said, it's a good quality sleeping bag and keeps you warm, and cozy when you're sleeping in it. The zippers are easy to operate and you won't have to fight them to make them work. The colors are nice and correspond with the images given. It packs away quite easily when you don't need it out. ... show more
