I purchased 2 Chair-Paks for my wife and I to go deer hunting in Michigan. We were able to bring enough gear in the packs to go back in a swampy area, having to build a make shift log bridge to cross a stream. The fabric held up very well against the thick brush.
We like the low profile of the Chair-Pak as we did not sit in a blind. I actually shot my prize while wearing the pack on our way back out, and it did not interfere with my rifle. Chair-Pak was the perfect size for a quick day trip of hunting. I liked it so much I purchased 4 more for the hunters in our family as Christmas presents.
