  Extraordinary odor-resistant plastic bag. 3 pack. Although these O.P. Saks look like ordinary zip lock plastic bags custom sized originally for Ursack, they are not.  These patented bags provide 17,000 times more odor resistance than high density polyethlyene.

  What makes the OP sacks so special.  Wouldn't a 1 or 2 Gallon Freezer Strengh Ziplock work just about as well ??

  Though I like them and use them, one thing about the OP sacks to consider is that they're not made "thru-hiker tough", and I found they literally came apart at the seams. When you're cramming 7+ days of food into one, it strains the seams and the open up, effectively becoming useless. The solution was to carry plenty of extras. 

I used OP sacks to store food, toiletries, medicines, trash, and my cookset -- all of which could potentially attract bears with their scent. The food sack was in my aluminum lined Ursack, but even if I used my Garcia or Bearikade, or no can at all, I would still use the OP sacks -- anywhere, anytime. Little rodents can do a lot of damage, and I had a bigger problem with a demonic and aggressive squirrel than bears on my JMT hike last summer!
