WATCHFUL EYE Opsak Barrier 28"x20" 2pk

I accidentally ordered these huge bags, but they worked well for our backpacking trip. We had no issues with insects, or creatures large or small. Sealed well and were durable enough that I will be able to reuse them several times. Easily fit 3.5 days worth of food for two adults and a child, with tons of room to spare. This size stuffed full would take up most of my backpack (50L), so be aware of that.I'll definitely order smaller next time, but these would be appropriate for car camping or for much larger packs.

Works good. Ziplock is a little awkward.

Going camping in the Big Horn Mts in a few weeks. These came highly recommended. I hipe they do their job.

We bough these to keep our food ( and eventually trash) in, while backpacking in Alaska. I bought an assortment of bags, and these were the most expensive but performed the worst. After the 2nd or 3rd time closing and reopening, the plastic part on top of the zipper seal rips off, leaving you with only the zipper part. I eventually damaged the zippers themselves. You have to tear at the zipper part becuase the lip you are supposed to grab always rips off after a few times opening and closing.As far as being smell proof, these are excellent. I believe that if your application requires a single time closing and re-opening, and your #1 concern is a smell barrier - this is what you want. If you are looking to reuse these bags a few times, get the cheaper kind.

i don't know what's wrong but i put all the food in these bags and put the bags in the cooler. everytime i open the cooler (not the bag) i could smell everything.

Huge bags. Can put a lot in it. Very tight seal, and it did the job. The shipment arrived perfectly.

These will suffice for intended usage but mine developed holes during first use. Admittedly, they were stuffed tightly in my backpack but was disappointed it didn't stand up to repeated packing/unpacking of one camping trip. I expected them to be tougher but it is only a thick flexible plastic bag, after all.

Going camping in black bear territory, I wanted something to put dog food and treats in that would keep the scent from attracting bears (dog treats are quite smelly - and the bears like that smell). I decided to try these bags. Wonderful! I put the bag of marrow bone treats in the bag and sealed it - no smell. But you don't realize just how well it works until you open the bag - Whew! The smell is so intense. Seal the bag back up - and nothing, no smell again.If you have anything that is really smelly and you want to keep the smell from permeating everything else, these are the solution. They really really do what they say they do.One note of caution: when you open the bag, be prepared for that intense smell - it will be at least 3 times more instense than the smell normally is.
