Been looking at dry bags recently. I have noticed that they are made predominently from either ripstop nylon or heavy PVC, the latter seeming to be more expensive. Sea to Summit stuff seems OK so haved looked at them but they seem expensive for what they are.
Question is, do people prefer the the nylon or the PVC? WRT the PVC, I notice that BCF (boating camping fishing) sell a range of PVC dry bags that are quite "cheap". I decided to buy a 10L and a 20L bag from them. While 10L seems like a decent size, once you roll the thing up it' not big at all. The PVC seem a lot more durable but they also seem to take up more room as they are stiffer. The other thing I may need to consider, I ever I want it for hiking, the PVC will be too heavy. What are your thoughts?
