One trip - used hard, and it functioned very well.
"Used on a turkey hunt. Works well and seems durable. Zippers work and it and holds weight well (I probably overloaded it, my traps were dying). Found a 5pt elk shed and a 5x5 dead bull, strapped rack (along with the other stuff in the pack, including a turkey hen decoy) and all held up well. Used hydration bladder-functioned well. Straps are comfortable. Could've used the waist strap to help relieve the weight but I removed them due to clashing with my war belt (I have higher-waistband pants for backpack comfort)."
