Review on 🌊 Sea to Summit Compression Dry Sack for Sleeping Bags by Andrew Young

Ordered to compress a sleeping bag and keep it dry while traveling through frontier waters. It worked for this purpose, although the sleeping bag was never exposed to wet conditions. However, we used it for a different purpose on the trip, which was to store groceries for the night. Although the bag is water resistant, it is definitely not waterproof. We left mine in the rain for several hours overnight and the contents inside got wet. Could this be because the bag wasn't compressed and water got in through the holes (it was rolled up, just not compressed)? In any case, a "waterproof" bag must be waterproof at all times.
