Great for backpacking!

I use these for everything! I recently went backpacking and everything went into a Sea to Summit dry sack. I used the 13L for my tent (Kelty Salida 2) and 8L for my sleeping bag, although after compressing it down in the bag, my tent ended up smaller than my sleeping bag! I've used various other sizes for other gear, clothes, and food. These are very thin (lightweight) but seem to be pretty durable and definitely kept everything dry during several days rain.

I'd go for the 8L to be on the safe side. If the sleeping bag compresses smaller than 8L you can always roll the excess dry-sack material up into the top. I use a 20L model to carry my 40 degree bag, sleeping pad, base layers, insulating layer, beanie, and gloves, and I still have a little extra room in the top, and it still fits horizontal across the bottom of my 80L backpack.

Light and well made

I got a 2L sack to keep all my small backpacking gear in so it stays organized; works great. The Ultra-sil is noticeable thiner and lighter then the regular sea to summit stuff sacks, but feels plenty strong and they seem very well constructed.
