Hyperlite Mountain Gear Prism Pack

With a 40L capacity, it is designed primarily for fast-and-light alpine day missions or ultra-light overnight bivy trips. If you are carrying a full traditional camping kit, you may find the volume restrictive.

These composite materials are exceptionally abrasion-resistant and designed specifically for the rigors of climbing. While they are incredibly tough, you should still exercise caution when strapping sharp, exposed metal directly against the fabric.

Yes, the hip belt is fully removable. This allows you to strip the pack down to its bare essentials when you want to save weight or need more freedom of movement while climbing.

The A-frame carry is robust and adjustable, designed to handle most standard backcountry touring skis. However, if you are using extremely wide powder skis, you may find the fit tighter than with narrower mountaineering skis.

While the pack is rated for 50 pounds, it is optimized for a lighter, more agile load. At the upper end of that capacity, the low-profile design will feel very stable, but you will notice the lack of heavy-duty suspension padding compared to a dedicated expedition pack.

The extendable closure provides a secure seal against the elements, but it is not a fully waterproof dry bag. It is best to use internal dry bags or stuff sacks for your essential gear if you are expecting severe, prolonged precipitation.
