LOKSAK Opsak Barrier OPD2-12 X 20, Inner Dimensions: 12.25x 20,2pk Storage Bags

This is an odd product. I say that because when I first purchased them back in 2018, the ones I got worked great! I was very happy with them. I used all different sizes and I had very good experiences with all of them. After thousands of miles on Trail they started to wear out (completely expected and ok at that point) so I bought some replacements, however, the new ones had different closures.. these closures proved to be problematic and defective..:( Either they wouldn't close all the way, or they would rip within a few open and closures. These are very expensive for that to occur. Ultimately, I started using "smelly proof bags" for lining my Ursack instead of opsak. Not only have the smelly proof bags been tested with bears, but they are cheaper, and lighter..I really liked my first opsaks, but I think they did some re-engineering that hurt them.. that said, a friend just got some new Opsaks, and they have the old black seal at the top, (which were the ones I originally had that worked great) so it's quite possible opsak realized their defect on the green seal ones and went back to the older style. If my smelly proof bags wear out, I may give opsak another try.. but for now I'm happy using the smelly proof. For reference 2 of smelly proof bags at roughly the same size as the 12x20 opsaks will cost you roughly 9 dollars versus roughly 14 for a 2 pack of opsaks.If I was basing my review off my first purchase of opsak, this would be a 4 star review (minus one star just due what imho is a crazy high cost) the best thing to do is if you go with opsak, when they arrive, test the seals several times before heading out.

Spot on

Love this product. Quick delivery

These Opsak bags did indeed keep food odors from escaping the bags. But one of the bags split open along the zipper seam the first time I used them. SUGGESTION: do not zip them closed all the way air tight, until you are on the trail already. They are good, thick, high quality, odor proof bags.

Just the right size. We were able to almost all of our food for a 2 night 3 day backpack for 2 people.
