Shot in the dark here. Bough this Stoic Somnus 30F bag recently here on BPL and I bought it despite it being a "long." I'm a moderate height guy so I'd like to trade for the regular bag so it's a better fit. I would also consider a trade for a Somnus 15 Regular and I'd kick in a few bucks.

This is the Center zip 800FP version in red/grey. 11oz of 800FP goose down. Bag weighs 25.75oz/729g on my scale.
Very good condition, I've never slept in it, bought it off of BPL member and it's in excellent condition. Comes with cotton storage sack, and compression sack (not shown).
