Description
Description
The smaller volume Altra packs, (Altra 33 through 50) keep weight to a minimum by using the efficient C2 (Composite Construction) system. The larger volume Altra packs (Altra 62 through 85) have a Load Transfer Discâ„¢ that pivots to increase agility and stability on rough terrain and combine the C2 (Composite Construction) suspension with Gridlockâ„¢ shoulder straps that adjust for custom fit.
Trekking Near or Far
Composite Construction (C2) eliminates back panel layers to reduce weight without compromising on structure or comfort. The pear-shaped Altra design holds the pack close to the body, minimizing load movement and backward pull for extended comfort and energy efficient movement under weight.
Thick Skin
All Arc'teryx packs use premium fabrics. The textiles used in the Altra series are chosen for durability. 210D nylon 6,6 ripstop fabric is tear-resistant and long lasting; heavier weight 500D aty nylon 6,6 protects high wear areas and resists contamination from dirt, snow and water pick-up.
Suspension Details
In larger volumes, 62-65L, 72-75L and 85L Altra packs offer full adjustment of the shoulder straps with GridLockTM, a unique system that adjusts straps for both width and height. In larger volumes, 62-65L, 72-75L and 85L Altra packs offer the rotating Load Transfer Discâ„¢ that distributes weight to the hips on uneven terrain.
Efficiency
Space efficient compartments, one-handed timesaving closures and pocket configurations make Altras the lightest weight, fully featured bags in their class. Wingmanâ„¢ side pockets wrap over the hip and are accessible without taking off the pack.
