I bought two of these Uberlight drysacks, a green 7L one for my GoLite Ultra 20 quilt and a orange 10L one for my wife's 15F rated 800FP MEC Merlin sleeping bag.
The claimed weights for these drysacks is accurate at 15g for the 7L and 17g for the 10L.
The shape of these drysacks is rather long and narrow, which makes stuffing them with sleeping bags a bit difficult. Since these are a roll top design, it would be better to get a larger (fatter) size for a negligible weight penalty and then roll the top to reduce the volume. 10L would be a nice size for down quilts and 30F rated bags, and 13L is a good size for colder (15-20F) rated sleeping bags. My wife's 15F bag barely fits into the 10L drysack (it took me 5-10min to get it in there) and it's too long to fit horizontally in her pack, so I have sent it back and ordered a 18L one instead.
Besides the shape being a little skinny, the drysacks seem great. The quality of construction looks excellent and the cuben seems very well bonded. I was stuffing really hard to stuff my wife's bag into the 10L sack and it has no trouble handling that abuse. The colors are also great. They are impressively vibrant for cuben. The green really looks nice.
One other minor critique is that there is no pull tab on the bottom to help you yank your sleeping bag out. I didn't find it hard to work around this, but a small cuben tab on the bottom would weigh nothing and add a bit of functionality.
- Vibrant Colors
- Well Constructed
- Lightest Drysack
- Skinny Shape
- No Pull Tab on the Bottom
EDIT: I switched to the 10L size for my Ultra 20 down quilt and the 18L size for my wife's 15F rated down sleeping bag. These are much nicer to stuff and you can still adjust the volume down to what you like with the roll top. It's definitely worth the 0.1oz to not be frustrated and wasting time in the mornings trying to cram your bedding into a undersized sack.
