Review on 🌊 Sea to Summit Compression Dry Sack for Sleeping Bags by John Pound

I have this to squeeze two king size memory foam pillows together that are full, bulky and heavy. I have this product with a 30 liter capacity (ie the largest size available at the time of purchase). The hole diameter isn't that big, so it was a little awkward to insert. They barely fit enough for me to roll up the top as directed. But I managed, and then it shrank to about 40% of the original package size. I left it compressed for maybe 5 hours and when I took the pads out they recovered and didn't look damaged. Success! Now that I travel with my pillows, I can do it with less volume. An expensive solution to an unusual need, but I wanted to share my experience in case others want to try the same. It would be nice if they made this product even bigger.
