User Review: The North Face Men's Cat's Meow
Temperature Rating: 20F
Weight: 3 lbs
The coldest I've slept in with this bag is about 35F, which was comfortable. But I don't think I would go much colder than that, certainly not the 20 it is rated for. Definitely a 3-season bag (I split time between mid-Atlantic and upper-NW). Other than that, it is light and compresses well. It does feel a little tight, but I am new to mummy bags. It is still new, so I can't comment on losing loft.
