Coleman Big Bay 20° Mummy Sleeping Bag Review

We feel the Brazos is relatively durable, fairly warm, and quite inexpensive. Durable zippers and a draft tube allow for easy entry and exit. Outside fabric is too silky, making bag hard to roll tight and get back into carry bag.

This bag should last you for many years, and to ensure it does, it comes with a 5-year limited warranty against manufacturer defects and workmanship. coleman canopy “No-Snag” patented zipper plows fabric away from the zipper to prevent snags. Added “Thermolock System” reduces heat loss through the zippers.

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). Along with a healthy dose of 550-fill down, the bag offers cozy warmth and good compressibility. And considering the typical price of coleman chair a down bag, the Cosmic Down’s $165 MSRP really stands out. My daughter had a big sleepover party and one of her guests borrowed it for the party. She told me the next day that it was the most comfortable sleeping bag she had ever used. She said lots of the girls were sitting on it with her during the movie because it was so comfy.

When I found my perfect picks, Coleman provided samples in order to facilitate review. The Big Bay is a mummy-style sleeping bag, starting wide at the shoulders and tapering around the feet. Mummy bags are becoming more popular because they’re lightweight and packable, and they’re easier for your body to heat up and keep warm (a sleeping bag is not inherently warm—your body heat gets trapped inside).

Extremely comfortable and wide enough to turn around in without getting tangled. Looks good after first wash and fits in front loader washer-dryer. 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. And if the bag has a tough exterior shell, you can use it as an outdoor picnic blanket in a pinch. 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.
