I love this stuff. Once you get a little practice and watch a few videos on line, it's easy to make a dry bag that would easily cost you $50 to buy from someone else.
I love this material for food bags. It's still lightweight, totally waterproof, and tough as nails. I find that a 1/4 yd makes a nice size zipper pouch which is good for food and toiletries for backpacking trips. A zipper pouch is a lot easier to rummage through than a stuff sack, and if made with a Uretek zipper and seam sealed, it is weather-proof for hanging. This weight of DCF is a fair bit stiffer than the flyweight stuff which makes it a good deal easier to sew.
Used the fabric to make a few bomb proof dry bags. Super sturdy and dry. RBTR shipped fast with excellent customer service
