User Review: Eureka! Men's Silver City 30ºF
Temperature Rating: 30º f
Weight: 2 pounds 3 ounces
Price Paid: $70ish
This is a 30º and no more (or less?). If it's below 30º I'll be taking a different bag. I am a cold sleeper though. It's also fairly narrow in the waist. I'm 5'10 and 190lbs and It's as snug as I care to be. If any larger, I'd go with the long version.
For a warm weather bag, I would think it very good. Packs very small and doesn't weight much. Just don't ask it to more than it promises.
