Thrupack - Summit Bum™ Classic

It’s a convertible pack that can be a waist pack, chest pack, shoulder pack, backpack pocket, etc. This is our flagship model and the unassuming design has inspired a number of lookalikes, none of which are as fully featured as the Summit Bum.™ This design is at the apex of being lightweight, durable, and highly functional. It’s designed to hold up to a 3,000 mile hike without leaving your side.

The Summit Bum™ series is a versatile pack-style that can be used in a number of ways!
