Removable Strap, Dual Attachment Points:

Customize your adventure with a removable strap and two attachment points on the back. This isn't just a pack; it's an extension of your exploration spirit, ready to evolve with your every move.

Luxurious Comfort:

Pair the Summit Bum™ with a Comfy Strap™* for the ultimate adventure luxury. Because every journey should not only be bold but also supremely comfortable.
