I have a Marmot Hydrogen 30 degree in near new I'm looking to trade. Made in 7/2013, bought new in 3/2014 and slept in for two nights with a merino base layer and socks. Turns out I'm a little bit colder sleeper than I thought- I'm looking to trade for a 15 or 20 degree bag of equal quality. Marmot Helium or WM ultralight, etc. I have cash I can add on for the right bag. Let me know what ya got! I can send detailed pics if needed.

Cheers!

Lucas
