This a great pack for the money. I have the coyote brown and the black. They hold up to abuse pretty well. I have several other more expensive packs but I use these the most. They do not have the creature comforts of a designated hiking pack like a Kelty, less padding for lumbar etc, but they carry a 50-60 lb load pretty comfortably. I guess the brown and balck are made of 600 denier and the camo are 1000 which explains the price difference. I have had no issues with mine, they make great all purpose camping, hiking travel bags. I usually use the black for travel looks classy and rock the coyote on summer hikes as the black does get a bit warmer in the sun. You could buy three of these for the price of some similar packs and Mine has not failed me yet.
