SO glad I purchased this pack. At the time I was shopping this pack was out of stock. I went back and forth deciding if I wanted to purchase the Pintler or maybe pick up another pack from Mystery Ranch. I am glad I waited. The turn around time before the pack was back in stock was not very long and Guidefitter did a great job of getting my pack to me in a timely manner once it was available. The pack it self is perfect for a day trip and even a 2-3 over night trip. The zipper lay out is universal is so many ways. If you are looking at the pack from the front the zipper lay out forms a "Y" allowing to to access gear from the top or from the bottom giving it the ability to allow you to retrieve gear without unloading your pack. The seams for the zippers and the pack as a whole are sturdy and thus far seam to be leak proof. Organization is plentyful. on the outside of the pack you have two pockets that sit at the top of the pack for quick access to head lamps, tag, knifes, etc. On the inside of that pack there is more than a handful of pockets some with enough room to hold a spotting scope. The amount of pockets make it extremely easy to organize gear. The Pintler has the loading shelf that, if I'm not mistaking, has the ability to hold up to 150 LBS of game meat or other gear on the trek in. It is extremely easy to access the load shelf and it comes across as intuitive. I would recommend that you follow the size chart and make sure you take accurate measurements to insure you purchase the correct size and to increase comfortability in the field. I would highly recommend the Pintler if you are looking for a jack of all trades pack. Great Job Mystery Ranch!
