Geckobrands roll top stuff sacks

Not sure about sizes. I use the yellow as my food bag when backpacking (fits up to 16000 calories for me, if you go for more dense foods like nuts and chocolate). I use the blue for electronics and my puffy jacket (it’s a women’s small, and it’s a snug fit in this bag, to give a sense of size). They’re not fully waterproof anymore, as I bought them at least 8 years ago. They’re still great stuff sacks, and in a 3 hour downpour, my puffy only had light condensation-level moisture on the outside when I pulled it out to dry.
