Description of Arcteryx Miura 30 Pack For craggin efficiency the Miuras combine the RollTop closure system with two fully-separating side zippers, which allows the user to peel away the front panel of the pack and gain immediate access to its entire contents. Large storage pockets and internal gear racking loops will keep even the most seasoned dirtbag organized. Built with tough ballistic materials, these packs are roadtrip ready. Features: Rolltop Closure: A simple and fast closure system that forms a wide opening for loading gear, and separates to initiate the drawbridge opening Removable compression straps: The compression straps are removable and modular; allowing gear and ropes to be strapped to the front or top of the pack Kangaroo pocket: A large external pocket that is accessible via zippers on the outside and inside of the pack, providing easy access to its contents while the drawbridge is open Padded sidewalls: EV50 foam pads the bottom and sidewalls to protect gear from impact and to buffer their hard edges from abrading the outer ballistic materials Hydration port: Made of Spacemesh, this overlapping port allows hydration hoses to be passed through with ease and will not constrict the flow of fluids Shoulder straps: For integrated support, these laminated shoulder straps are attached directly to the framesheet and are made with EV50 foam and breathable Spacemesh for next-to-the-skin comfort Aluminum stays: Made with 6061 Aluminum, the dual stays are aligned in a V position to direct the load to the pivoting hipbelt. The stays are shaped to mimic the contours of the back, and are connected to the framesheet for unified support. Dual density framesheet: This laminated framesheet utilizes EV50 foam to cushion the backpanel and HDPE to provide a rigid anchor point for the suspension system. The shoulder straps and aluminum stays are attached directly to the framesheet, delivering powerful integrated support Top loading Full-separating front panel RollTop closure Dual full-length side zippers with opposing thumb loops Two internal gear racking loops Top pocket Kangaroo pocket with external and internal access zippers Two top grab handles Two modular/removable external load straps with quick release buckles Hydration bladder clip and hose port Anatomically shaped hipbelt and shoulder straps Spacemesh backpanel Shoulder straps and hipbelt HDPE framesheet 6061 aluminum stays 630D superpack plain weave 630D superpack ballistic weave 210D nylon ripstorm Spacemesh Hypalon trim EV50 foam Regular: 1.9 kgs (69 oz), 30L (1831 cu. in.)
