I've got a new 16 degree Marmot down bag a few months ago for my SOBO thru-hike that I'm starting in 2 months.
I've used it maybe 10-15 nights since I got it and it's starting to develop a faint stink. It's not really bad and I'm probably going to wash it it soon, before my thru at least, but I'm concerned about this being an issue on the trail. I've been considering getting a liner to try and avoid getting my stank on the bag itself, which leads me to concerns about getting hot with a liner and a warm down bag.
Are stinky bags commonplace on the trail? Should I even be concerned?
