Arc'teryx Altra 75 Pack

The Arc'teryx Altra 75 pack is built for long-range comfort and big-load stability with a hybrid design that unites a supportive suspension with lightweight materials and breathable comfort. Highly breathable AC2 MonoFrame™ system creates a direct link between spine, suspension and bag. Rotating Load Transfer Disc™ allows the hipbelt to pivot, following your natural movements for agility and stability. Anatomically-shaped shoulder straps feature a core layer of perforated, air-permeable EV® 50 foam lined with breathable Spacermesh™ for next-to-the-skin comfort. Injection-molded GridLock™ shoulder strap adjustment is laminated to the MonoFrame, allowing personalized adjustments to be made both vertically and horizontally. Thermoformed, triple-density hipbelt promotes airflow and evaporative cooling. Aeroform™ back panel features small peaks and valleys with resilient monofilament nylon mesh that provides airflow next to your body for cooling comfort. Composed of EVA foam, Kydex plastic and twin removable aluminum stays, the suspension is bonded directly to the pack body for comfort and stability. Removable and expandable top lid has 2 zippered compartments and a map pocket. Extendable collar with drawcord adds capacity to the main compartment for large loads. Top-loading pack body also features a full-length, inverted U-shaped zipper, allowing quick panel-loading access to the main compartment. Hydration-compatible design features reservoir sleeve with a HydroPort™ and hose clip for drinking tube (reservoir sold separately). Kangaroo pocket on front of pack is perfect for stashing raingear or other items that you may need to access quickly. 2 stretch-mesh side pockets with elastic drawcords secure water bottles. 4 external compression straps let you cinch down your load for jostle-free carrying; padded compression wings and micro daisy chains allow additional storage configurations.
