3-Season or Winter Sleeping Bag Stuffsack Options

How about no stuff sack at all? Just stuff it in bottom of pack and let it conform to the pack? Also 1 less item you have to worry about searching for when packing up. I have ditched all stuff sacks years ago. Save a few dollars and a few ounces too..

I should do that but the two things I can’t get past is 1. I like added redundancy on the sleeping bag to keep it dry, I live in a wet area and even with a water resistant bag or a liner I worry about the critical piece getting wet. And 2. The shell fabric getting beat up, I worry about it getting poked by something else in the bag.

At some point I may get over those concerns, but for now I like a little extra protection

How about a trash compactor bag or a Nylofume bag?

During the winter when I expect wet snow in the Sierras, I line my pack with a trash compactor bag. I then insert a 30L Sea to Summit dry bag and proceed to stuff my sleeping system, sleeping clothes, and my after dark clothes (e.g puffy jacket, puffy hat) into the bag. I push everything down from the top, then I close up the Sea to Summit bag with its roll top closure. Next comes my shelter (MLD Duomid). All the pack contents are protected by the trash compactor bag. All the insulation is protected by the trash compactor bag and the Sea to Summit bag.  The two bags do dual use because I often use the pack as a layer of insulation underneath. The trash compactor bag and the Sea to Summit bags help organize gear under my tarp. I do bring a stuff sack for odds and ends at night, like things I remove from my pockets when I use all my clothes as part of my sleeping system.
