Review on Dri-Sak 🎒 Original by Snugpak by Matt Jenkins

Having purchased similar items in the past I decided to test them thoroughly to ensure the manufacturer's claims were verified. At first I was skeptical that simply folding the bag would actually stop water getting in. My first test was the rain test. I put a few pieces of 8.5 x 11 paper in a bag and sealed it according to the instructions. I then ran it on full blast with hot water for 20+ minutes (to see if the heat would affect the integrity of the material or stitching). I kicked it, splashed water, turned it over, etc. After 20 minutes I opened the package and the paper was just as dry as when I started the test. The second test was an immersion test. I left my original paper in the bag, added a few stones to the weight, resealed and placed in a large sink of hot water for an hour. Opened - the paper is dry! I repeated the second test for 2 hours, this time with cold water and the result was only slightly different, this time the paper was slightly damp but there was no trace of water droplets. I believe the reason for the humidity was the temperature difference in the water. I switched from hot to cold water and believe this has caused moisture to build up in the bag. This is a perfectly acceptable state of affairs, and it is impossible to engineer anything against it. Overall, the bag exceeded the manufacturer's specifications, at least in my tests. They say it's not designed for continuous water immersion, but from my perspective it did an excellent job!
