This was a little funky carrying on my back (I felt a little like Master Roshi on Dragonball). IT'S SO DANG HUGE! I felt like a sail was strapped to my back. This was much appreciated when we actually laid it out. It made it much easier to move around under the climber. The fabric seems pretty tough and built to last. It did a great job of giving lots of cushion for falls and covering a lot of area. We had a few falls from roughly 20' and I was very impressed with the level of absorption. It was a little of a pain finagling it into my teeny car, but it fits! Can't wait to take it on more bouldering trips!
