Like the aLoksak but odor-proof, the Opsak is a great solution for storing food without attracting wild animals or sniffing dogs to your campsite. They also serve to transport body waste from areas where you want to minimize traces and evidence of your presence. Just keep the bags you use for one or the other strictly separated!

Sold in 2-packs.

Resealable and reusable for many, many times. The seals will eventually wear out and it requires replacing the bag with a new one but it takes a good while. The Opsak withstands pouring boiling water into it and can be used to rehydrate freeze-dried food.

Features

For such a simple product, the Opsaks have a long list of specifications. They are made from FDA and NSA-approved medical-grade materials for food and biohazard storage.

The dual seal is very precise and may require getting used to. The feedback of getting a proper seal is not audible so start at either end, align the tracks carefully, and trust your fingers.
