It puffs up about half an inch, so kind of good. The bag is machine-washable and the lightweight design fits easily in both the washer and dryer. If they wanted to skimp on fabric, it should have been used on the outside and bottom of the bag! Not on the interior where comfort is the main issue.
I did a good bit of research before purchasing ours. Of course, I wanted something that would keep us warm. Mummy bags are very effective for keeping warm, but I am not comfortable in a confining bag. We bought two Ozark Trail 30-Degree Sleeping Bags. Keep children comfortable during nights in the tent inside the Ozark Trail Kids 2-lb Sleeping Bag. It is made from a breathable polyester material that keeps little one’s snug while they sleep.
I notice this isn’t the first review with this complaint. The zipper broke on my warm weather bag ozark trail chair on the second night out. Too bad too because overall I’ve had good luck with Ozark Trail stuff.
It’s compact, and keeps you warm and comfortable throughout the night. It has ClimaTech fiber for added warmth, comfort, and durability. I bought the zero degree bag and nearly ozark trail canopy froze to death. Day one, night one…the zipper tore and cord in hood broke. Day 2 …it was closer to 6 degree and I froze…I had to hike into town, replace the bag.
By the time we got back from camping the next weekend three out of four sleeping bags had the zippers broken. I’m so disappointed with this product that I advise anyone buying sleeping bags not to even look at Ozark and buy Coleman instead. I used this bag from February of 2002 to June of 2002 on the Appalachian Trail, and I still have it. The first night out it was less than 14 degrees F, and I had at least 50 nights under 40 degrees F. I can’t say I was warm, but I wasn’t shivering, freezing, or cold either, although I did wear 2 layers of clothing. I won’t ever buy an expensive sleeping bag after carrying this cheapo, unless I can find a cheap bag that weighs a lot less.
