I've been at it again. As part of my handlebar gear setup, I've been trying to get everything to a length of about 18". I already made the stuff sack for my sleeping bag, but I wanted a smaller one for sleeping clothes or other items.
So here is the stuff sack. The fabric is waterproof and the seams are sealed. There could be a chance of water getting in the end but that is minimized with the flap.
And it was fast to make. Total time? about 20 minutes.
The entire stuff sack.
The end of the stuff sack. I wanted some color contrast.
Here is the water flap. Once you get all of your gear in it, you push this flap in and pull the draw strings taut.
