User Review: The North Face Men's Cat's Meow
Temperature Rating: 30
Weight: 2lb 10oz (advertised)
Price Paid: $150
We purchased one for me and one for my wife. There were no defects in workmanship in either bag.
Our first use was an overnighter in the Manassas Gap shelter on the AT at the end of October, 2007. It got into the 30's that night and we both froze in these "20 degree" bags. I mean we were flat out miserable.
We used them several times after that in temperatures that dipped into the 40's and did ok.
I'm not sure what the rationale for rating a bag for much lower temperatures than it's capable of withstanding is. I certainly would be leery of buying anything from North Face again and I'd never buy anything from them that I couldn't get from another source.
