Review on GSI Outdoors Lexan Gear Large by James Mcphearson

Purchased as a kayak gear to store electronics. As others have pointed out, it was in a deep vacuum when it arrived, although that was in the 90's. You have to turn them off in a very hot factory near sea level. Insert the knife into the slot on the front latch and gently press until air begins to seep in. It's a good size for a DSLR and an extra lens for beachside wildlife photography. Almost transparent with a green tint it's a plus for looking at your phone or GPS without worrying about it getting wet, but it does get a little hot in the box if you don't keep it in the shade when You are traveling the water. Exactly what I was looking for.
