Evening,
Would this product benefit for use as a food storage bag when back country camping?

I've also used it as a food bag - it holds plenty for two people and works well. It hangs from tree lines easily and does as good a job at keeping stuff from getting out as it does at keeping water from getting in.

I used it as a food bag and hung it, worked great for awhile until I let it down too fast and it abraded on the rock surface on the ground that put some holes in it. I still use it as a general stuff sack but lost its seal.

Yes, this is good for food storage. I would suggest, however, getting the thicker sea to summit bags. I used those every day on my thru-hike and walking through 14 states and 2,200 miles, I never once had an issue with animals of any size smelling or dealing with the bag. If you have an airtight seal, that basically means its odor proof as well, So it works very well. Easy to hang if you feel the need to, and extremely durable.

Depends on where you are, these are in no way shape or form animal proof. If you are in bear country stick with a can, if rodents are your worry then this may work if hung properly. If anything you are trying to keep out gets ahold of this you are probably gonna end up hiking out hungry! Good Luck
