Along with being 100% water/air tight like our aLOKSAK, the OPSAK (Odor Proof SAK) is also a 100% odor barrier bag. We use the same seal on our OPSAK that we use on our aLOKSAK, but with a different film that is odor proof and withstands higher temperatures. You can store food undetectable to bears and other pests in your campsite by sealing it within an OPSAK. Also, because the OPSAK is FDA approved food-safe, you can use it in food preparation and storage. You can even pour boiling water into the OPSAK because of its extreme heat resistance. See below for product details.
