I'm coming to USA from Australia and looking for a sleep system where I wont freeze my balls off. I'm gonna be doing the Utah/Arizona national parks in the shoulder seasons, and currently my sleep system consists of a shitty ~50f sleeping bag that simply doesn't cut it. I've been cold in it so many times I've lost count!

I like the look of the EE Revs that can completely unzip so it provies a bit more versatility, thinking 20*f is the sweet spot where I could wear some clothing to sleep accurate to rating, and open it up for the warmer weather we get here in Oz 3 seasons.

Anyone got anything lying around & happy to part with? I have a US address and paypal sorted too.

Cheers peeps!
