- Custom Fit-on-the-Fly Hipbelt – The hipbelt features an adjustable, tool-free system that lets you fine-tune the fit while wearing the pack. This ensures optimal weight transfer to your hips, reducing shoulder strain and improving overall comfort during long carries.
- Custom Fit-on-the-Fly Shoulder Straps – Shoulder straps can be adjusted on the move to match your torso shape and load distribution. This personalized fit enhances stability and comfort, especially when navigating uneven terrain or adjusting pack weight.

Benefits & Use Cases

Its 70-liter capacity is ideal for week-long trips where you’re carrying a tent, sleeping bag, cooking gear, and extra clothing.

The Stow-on-the-Go pole attachment is especially useful for alpine terrain or long approaches where trekking poles are frequently stowed and deployed. This pack is a strong choice for thru-hikers, expedition travelers, and anyone prioritizing load management and adaptability in the backcountry.
Important Notes
The raincover is included with the pack and should be used in wet conditions to protect contents from moisture. Always ensure the hipbelt and shoulder straps are properly adjusted before setting out on a long trek to maximize comfort and load distribution. The removable DayLid daypack is intended for light to moderate loads and may not support heavy gear. Regular inspection of zippers, buckles, and attachment points is recommended to maintain pack integrity over time.
