Roll top bags other than DCF?

Yeah DCF can’t really handle the torsion at the roll top – particularly if you roll it tight. It eventually delaminates in that area.

Sea to Summit has their Ultra-Sil Nano dry sacks that are a 15D silnylon rather than their usual 30D silnylon (used for the regular Ultra-Sil bags). At 19-24g (0.7-0.9oz) for 4-8L they are a bit heavier than DCF. I did accidentally rip one once stuffing a sleeping bag a bit too hard, but with a more gentle touch they’d last a long time. Usually I take the 6g penalty and buy their 30D nylon ones, but the 15D is a viable option.

I have both of the STS bags that Dan mentions and agree that the Nano is a bit fragile. Perhaps more importantly I have found them to also not be entirely waterproof.  I’m not sure why but I have had them leak for no discernible (no obvious physical damage or failure to close properly) reason. I am retiring the Nanos for everything except my tent storage bag, which gets packed on the outside of the pack anyway.  The Nanos are however quite slippery and easy to fill.  The slightly heavier Ultra-Sils have been bomber.

For super lightweight organization I prefer to pack things in the STS mesh bags then everything goes in one large pack liner (Exped schnozzel). The mesh bags stretch, compact in the pack and the contents are easily seen.  Half the weight of the Nano dry bags, and no sign of damage after 5 or more years of use.

Another Sea To Summit user here (30D version).

I’ve also had good luck with the STS bags, both nano and regular ultra-sil. I have not experienced a leak with either, although TBH I haven’t deliberately tried to test them. I ripped a nano bag once while stuffing my quilt inside. Since then I’ve been more careful with them, but I am definitely continuing to use them.

Thanks for the input. I will look at the STS bags.
