Ordered these because I don't like to cook on the trail and I didn't like pouring boiling water into plastic baggies, so these seemed like the perfect solution and they are. Due to massive amounts of food allergies & sensitivities I have to make my own meals for backpacking. Loved the fact that I could write what was in them with a Sharpie, which didn't rub off. On a short backpacking trip, just 2 nights in the woods, I ate 6 meals leftover from last year's food dehydrating and meal prep and they were still very tasty and fresh. Getting ready to order another batch of these bags to start packing up meals from this year's adventures
