C-Clamp Sternum Strap Replacement

Introduction

Many Patagonia backpacks feature a removeable sternum strap, also known as a chest strap, designed to alleviate shoulder pressure and distribute weight more evenly across the chest.

 

This guide demonstrates how to reattach one specific style of Patagonia sternum strap - the c-clamp - named for its C-shaped cross-section. This style was used on some packs produced between 2009 and 2018.

 

Replacement parts are currently unavailable. To get a new sternum strap, take your pack in to a local Patagonia retail store for repair evaluation or send it in to Patagonia through their mail-in repair service.

    • Locate the sternum strap that has come off the pack.

    • Replacements for this style of sternum strap are not currently available, so if part or all of the sternum strap is missing, reach out to Patagonia for alternative options.

    • The 'c-clamp' piece of the sternum strap fits over a plastic tube or ‘rail’ that is inside the backpack strap. At the bottom of this rail there is a fabric flap.

    • Pull back the fabric flap to expose where the rail ends. This is where the c-clamp was designed to be slid on and off.

    Edit

    • At the exposed area at the base of the rail, slide the c-clamp back onto the rail.

    • Pull tightly on the fabric flap to expose the area.

    • Maneuver as if parallel parking a car. Start at an angle, slide partially onto the rail, and then straighten out.

    • This can be difficult to do, don’t be shy using some muscle!

    • Repeat the steps above on the other backpack strap.

This is helpful, except where do I find the replacement part! I contacted Patagonia and they no longer make it; they said to try a local sporting goods store or to send to Patagonia and they'll sew on a new daisy-chain version. My local REI does not have these parts either. Bummer!
