With its lightweight design, ground-breaking suspension system and 3000+ cubic inch capacity, the Black Diamond Infinity 50 internal frame pack offers versatility for overnight hiking or multi-day backpacking.
Combining multiple design technologies, the extremely innovative Black Diamond ergoACTIV suspension system provides a full range of motion while ensuring stable load support. A contoured 6061 aluminum frame maintains stability while transferring weight to the ergoACTIV hipbelt. Employing a unique ball-joint attachment, the ergo ACTIV hipbelt allows unrestricted movement in any direction and far surpasses the performance of traditional hipbelts. Further enhancing performance, innovative shoulder straps are connected via an integrated low-friction cable that allows them to mirror your every move while maintaining a balanced load. A sliding sternum strap and load-lifter straps also help to improve fit. An OpenAir backpanel and soft, breathable mesh fabrics on the shoulder straps and hipbelt promote breathability while cushioning the Infinity 50 against your back.
A top pocket protects the Infinity 50's sizeable top-loading packbag and its height can be adjusted to accommodate loads of varying sizes. A large elasticized front pocket is perfect for stashing gear and doubles as a compression system that aids in load stabilization. Stretch side pockets provide additional storage space and a small pocket on the hipbelt is perfect for keeping valuables within easy reach. The Infinity 50 has integrated trekking pole/ice axe loops that retract when not needed to maintain a clean profile. A lined internal sleeve and drinking tube exit ports make the pack hydration system (not included) compatible.
The Black Diamond Infinity 50 internal frame backpack is available in M (torso fit range of 17.5"-20.5") and L (19.5"-23.5") size options and your choice of colors.
