The rolltop expands and contracts to accommodate whatever you need to carry and wraps the contents of the pack securely to eliminate bouncing.





The vest includes two zipper pockets and two stretch pockets for on-the-run access to your phone, wallet, keys, and running accessories.


The shoulder straps can carry two 500-ml soft flasks (not included) in the front stretch pockets.


Dual side straps create a body-hugging, infinitely customizable fit that can be adjusted on the run. Tighten the side straps to lock the pack against your rib cage and reduce bounce.

The Commute Pack fits high on the back and adjusts like a traditional running vest.

Reflective webbing increases visibility in low-light conditions.

The main compartment and laptop sleeve are lined with waterproof, seam-taped 70-denier recycled nylon for complete protection against water ingress.



The FKC has the carrying capacity and stability necessary for run commuting, but the fit and feel of a lightweight trail vest.


A dedicated laptop sleeve and waterproof, seam-taped construction protect your gear from the elements.

The FKC fits high on the back and adjusts like a traditonal running vest.

Reflective webbing increases visibility in low-light conditions.

The main compartment and laptop sleeve are lined with waterproof, seam-taped 70-denier recycled nylon for complete protection against water ingress.



Load the pack with the gear you intend to run with, and put it on. Let the weight of the bag settle onto its balance point on your back—neither too high, nor too low.

Tighten the side adjustment cords so that the shoulder straps are wide on your chest and very snug around your rib cage.

Attach the sternum straps. Snug the top strap, and then the bottom strap. Do not overtighten — most of tension should be on the shoulder straps, not the sternum straps.
