Hyperlite Mountain Gear Prism Pack

With a 55-liter capacity and a floating lid for volume expansion, it is well-suited for overnight or multi-day alpine objectives where weight management is critical. However, its design prioritizes speed and technical climbing over heavy-load comfort, so it is best for those who pack efficiently.

The diamond pocket is a specialized, reinforced storage area designed to securely house the sharp heads of your ice axes. This keeps the dangerous edges contained while keeping the shafts accessible on the exterior of the pack.

Yes, the hip belt is removable. This is a helpful feature if you are wearing a climbing harness and want to reduce bulk or if you are moving fast and light and prefer a more minimalist setup.

The pack is constructed from DCH150 and DCHW fabrics, which are highly water-resistant and durable. While it will protect your gear from snow and light rain, it is not fully submersible, so you should still use dry bags for critical items like sleeping bags or electronics.

The side compression straps are specifically designed to cinch the load close to your body, which minimizes shifting during technical movement. Combined with the streamlined, snag-free profile, the pack is built to move with you rather than against you.

The integrated back panel is designed with ventilation channels to help airflow. While no pack eliminates sweat entirely, this feature significantly improves comfort compared to traditional, non-ventilated mountaineering packs.
