Lightweight bear bag for long trips

The mountain silnylon would do just fine but I will say that the big benefit of using Cuben for this application is that I like to make my food bag somewhat oversized by adding height to it and with Cuben, it will stand up on its own so you can look through it more easily. With some like silnylon, the material would drive me nuts as it would flop all over the place.

JR: the issue is not with the trunk, but with little branches sticking out. It is very difficult in the PNW to get a tree that has branches sufficient for a hang that don’t have other branches in the way to some degree.

Hoosier: I appreciate the offer. It was 1.43 D hybrid Cuben fiber.

JW: Thanks for the tip. I have a sewing machine and probably can make one myself, albeit badly.

for what it’s worth, i made a clone of a zpacks bear bag for myself, only using cuben hybrid fabric. it’s way more durable than the normal zpacks bag and still pretty light. so you might try that approach.

although my “rock toss” satchel still gets puncture holes every time i miss the branch and it smashes down onto granite. lol.

i also agree that the normal size is okay for a weekender but too small for resupplies in the 5-7 day range. and if i were to make it again i’d add about 50% extra volume at least. i’d also make it box shaped at the bottom rather than envelope.

I made a silnylon one about 14″ long and 9″ in diameter, but it leaked. I coated it with sealant, but by the time I was done it was getting close in weight to a regular SeatoSummit dry bag for weight. So the last couple have been SeatoSummit dry bags. At 3.5oz they are rather disposable and rugged enough to hold up to abrasion and the occasional drop. I also pack most of my food in bulk baggies, so this also means my food is double sealed. The 13L size is perfect for 7days of food.

The Mountain silnylon is a particularly high quality, more waterproof, higher tenacity, and generally more durable than typical or average silnylon.

I’ve (and many others have) found silnylon is kind of hit or miss on the wider market. I’ve bought stuff which wasn’t fully waterproof, or also not durably so. It seems like the RSBR team is getting better and better at coming up with consistent quality fabrics at reasonable prices.

I’m a bit torn between using this or the 1.1 oz Silpoly for a warm weather tarp or tent. I wonder if the Mountain stuff stretches and sags a bit less since it has a higher than normal tenacity strength than regular silnylon?
