Waterproof Backpack Liner/cover

If I were in a situation where I potentially have to swim cross a river and couldn't touch the bottom, I would have a dry bag that would fit the essentials- eg. Sleeping bag, clothes, food, electronics. I would look into a big dry bag from zpacks or make your own.

thanks
i was just going to use food zip lock bags for important items in bag since they are cheaqp and great to use

but even the backpack would get wet…making it damp to carry around, not to mention heavier

i think i would need a big over bag that was waterproof for my back pack

We carry a large garbage bag each. If there is a serious river crossing to be done, or some swimming down the river, we carefully repack everything inside the garbage bag.
Works just fine for us.
Also very light and very cheap.

i was thinking of doing that!
but thought it may not work/needed someone with experiance if it works

but i would need it inclose my backpack too…dont want it getting wet and weighing me down

how do you make it waterproof though?
is there something you can do to make a tie/knot in a certain way at the opening so that my backpack/contents would be watertight?

would be good if i can trap air inside too…floating it across with rope would be great

please let me know :)
thanks!

not sure how to PM but it would be great to know how you did it Roger

or anyone else if they know???

Just leave a little space at the top, twist it closed, then tuck the twist somewhere where it won't come undone. Works for me, though I've never swam a creek like that.

Very, very complex … Not. :-)

Crumple the neck of the plastic bag together hard, fold it over once or twice (important), and then wrap a heavy rubber band around it several times, so it is tight. Works for us. (We use the big rubber bands the local post office use to bundle mail together … $0.)

Cheers

thanks for all the help guys, think im all sorted in this department now :)

thanks again
