Pure Mountain Running

Go Higher. Stay Longer.

Our Pure Mountain Running Line is for people who move through big country under their own power. Not for show. For outcomes. We built this category to solve mountain problems: stability under load, access without breaking rhythm, warmth and weather control without bulk. It’s a complete system—carry, light, hydration, accessories, tuned for steep decisions and long windows between aid.

At this level, the materials are not cosmetic choices, they’re mission-critical. Packs and vests in this line use advanced composites and reinforced textiles like UHMPE (a fiber up to 15x stronger than steel) integrated into multi-layer challenge cloth to resist abrasion from granite, shale, brush, and days of continuous movement.

Where stretch is needed, we use EnduraMesh XT, a true 4-way stretch mesh constructed from Nylon 66 blended with UHMPE fibers. It flexes naturally with the ribcage and diaphragm while staying resilient against friction and pack stress.

This line exists because some athletes require equipment that performs at the same level they do, on efforts where failure is not just inconvenient, but costly in time, energy, and exposure.

Pure Mountain Running isn’t about looking the part. It’s about equipment that stays functional when the terrain gets consequential. Choose the pieces that fit your mission, and go make hard feel simple.

The Purist Hydration Pack

The Purist is engineered for multisport athletes who demand maximum versatility and reliability from their gear. With a 22-liter capacity and a roll-top design, this pack carries everything you need for endurance adventures across any terrain. Massive side pockets offer fast access to essentials and can carry any UltrAspire hydration components. A quick-stash outer pocket with load compression keeps gear secure and manageable. The Purist is also reservoir-compatible for seamless hydration on the move. Equipped with removable anodized aluminum buckles, it provides durable attachment points for trekking poles, ice axes, or hose management. The harness system webbing and a sliding toggle ensures a secure, adjustable fit. The front harness features large zippered bottle pockets for weather protection, layered zippered pockets available at your fingertips, sweat-proof phone storage, and dual zippered top shoulder pockets for added organization and access. The MaxO2 Waist feature allows for a completely customizable fit on this pack whether empty or fully loaded. One size fits most. 

Built for Environments That Don’t Forgive Gear

The Purist is part of our Pure Mountain Running line, created for athletes who move through environments where gear is continuously tested by terrain. The primary body of the pack is constructed using challenge cloth, a three-layer composite that pairs high-density polyester with a UHMPE fiber reinforcement layer and a polyurethane film. This creates a fabric that is significantly more abrasion resistant than even military spec fabrics, while remaining exceptionally lightweight and ready to handle sharp rock, brush, and the constant friction of long days in the mountains.

Complementing this is our EnduraMesh XT, a true 4-way stretch mesh that flexes naturally with the body. Unlike typical stretch meshes that degrade under stress, EnduraMesh XT blends Nylon 66 for strength with 30% UHMPE fibers that are rated up to 15 times stronger than steel. The result is a pack that delivers both adaptability and long-term durability, built to move with you while standing up to whatever the mountain throws your way.

Mountain Racer Waist Pack

The Mountain Racer is a high-durability, high-capacity waist pack built to perform in demanding environments. Crafted from premium materials, it’s designed to carry your essentials and more, securely and comfortably.

The front features a large kangaroo-style pocket with an internal phone sleeve and a layered zippered pocket for organizing key items. Two additional large side pockets, each with compression straps and cord locks, provide secure storage for sensitive gear.

The rear compartment easily holds the included 800 mL softflask with a new locking cap. Light bracket compatibility allows for easy attachment of a waist light, and removable rear Z-pole attachments offer added versatility for mountain missions.
