Is there a cheaper alternative to this for a food bag? I've heard conflicting advice about keeping food safe from rodents (let alone bears). Some say to hang a food bag open, so rodents won't chew thru it, while others advise rodent-proof materials, which seem extravagant (and are costly) to me. Is even a sea-to-summit style, Sil-nylon, bag necessary? Won't a water-resistant sack do?
I know...a minor gear question...forgive my wonk.
