This is my 4th Mystery Ranch Bag that I own and the largest. I immediately bought it when I saw it on sale at Amazon. I’m very happy with my purchase and it didn’t disappoint. I just love the high quality, durability , design and versatility of Mystery Ranch backpacks. So far I have used this as my everyday carry when commuting and it feels so comfortable to carry around and hold all my daily essentials. I also have used this backpack for a 2 hour ruck with 35 Lbs without any issues; my shoulders and back felt great! I totally enjoyed rucking with this backpack. I will definitely buy another one when it goes on sale. I will probably get the army green one next time.
