It’s MORE Than a Fanny Pack

This is the lightest version of our most popular model.
It is made of Challenge® Ultra 200 which is one of the most durable and water-resistant materials available.
The Summit Bum design has inspired a number of lookalikes, none of which are as fully featured as the Summit Bum™ Classic.

At Thrupack, we aim for the apex of lightweight durability.
The Summit Bum is designed to hold up to everything that you can, without getting in your way and without weighing you down.

Ultra 200 is a woven ultra-high-molecular-weight polyethylene material that is laminated with polyethylene film on one side for added water-resistance.
It is the most durable material we sell and, if that isn't amazing enough, the seams are bonded with Mylar tape!

The Summit Bum™ series is more than a hip-pack.
It is a versatile, multi-functional pack that can clip onto your hip, your chest, or be slung over your shoulder, used as a pack brain while moving, or a variety of different ways!
The goal is a simple and clean design that allows the user to easily adapt it to their specific needs.

This pack features a removable strap and two attachment points on the back.

Use with a Comfy Strap™* for supreme luxury.
