Marmot Hydrogen used one night, bought it a few months ago and just had the chance to use it and it is a little small for my build! It dropped down to about 32 degrees and I was comfortable with just a shirt and shorts in it, it packs super light and is awesome I just need something a little wider for myself. Only packed for 1 night otherwise kept in the closet hanging up, sprayed a little febreeze on the inside and aired out like I normally do after an overnight, basically brand new condition.

 

Bought for 275 asking 225 shipped
