Know before you buy
The 'ND' stands for Narrow Dimensions. This indicates the pack is specifically tailored with a narrower back panel and harness geometry, designed to provide a more ergonomic fit for users with smaller frames.
At 18 liters, this pack is best suited for fast-paced day hikes or high-output mountain activities where you need to move quickly. It is not designed for multi-day trips requiring overnight gear, but it excels at carrying essentials for a full day on the trail.
While no pack can completely eliminate sweat, the Air Contour system is designed to promote airflow and stability. It keeps the load close to your body to prevent shifting, which helps maintain comfort during high-intensity movement.
Yes, the Protium 18 ND is hydration compatible. It features an internal sleeve and routing for a hydration hose, allowing you to drink on the go without stopping.
The pack is constructed from ROBIC 100D nylon ripstop. This material is chosen specifically to balance low weight with high tear resistance, making it durable enough for rugged mountain environments while keeping the overall pack weight down.
The trekking pole loops are designed for secure storage when you aren't using your poles. While they are accessible, you will typically need to take the pack off or have a partner assist you to stow or retrieve poles efficiently.
