I use this pack elk hunting and has awesome support on your hips and back. The adjustable back support that goes up or down for torso length is great. The v shaped zippers on top to access the main compartment is wonderful! The inside small zippered pockets and compartments are extremely handy. The internal /external frame gives the pack plenty of rigidity to haul gear. It's well thought out for its design and use to backpack gear in the woods. Very happy with my purchase as a full time outfitter, my gear is critical to my success and comfortability day and day out! Good work Mystery Ranch Packs!! #beausoutdoors
