Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“So she got one, but it's not mating properly. It seems the newer zipper has the fabric bit that covers the zipper on the inside, whereas the older one has it on the outside.”
“"Nothing" being relative to an uncompressed sleeping bag. Many bags will still take up quite a bit of space. My North Face Cat's Meow 20 compresses down to the size of a watermelon; even my fancy 900-fill-power down quilt gets only to about half that size. Sleeping bags are still one of the bulkier items.”
“If you’re 6’ tall definitely get the long. I got the 20* for my 5’8” wife and there isn’t an inch of room left in length. I also got an awesome deal and got it for $40 brand new. But that’s a different story.”
