Gear To Gravel: The Topo Designs x Trek Bike Bag

Every so often, a collaboration comes along that just makes sense, like a cold beer after a dusty trail ride or a perfectly tuned derailleur. The Topo Designs x Trek Bike Bag is exactly that kind of union—a meeting of minds between two outdoor heavyweights that brings a much-needed splash of color and relentless utility to your handlebars. Whether you’re navigating the urban sprawl on a morning commute or getting lost in the backcountry on a weekend bikepacking mission, this bag is engineered to be the ultimate companion for your essentials.

At the heart of this collaboration is a shared love for the “New Outdoor”—an ethos that prioritizes accessibility, style, and getting outside by any means necessary.

The bag itself features a unique “party/grid” aesthetic, blending vibrant patterns and organic lines that pay homage to both Trek’s high-performance heritage and Topo’s signature bold styling. It’s a limited-edition look that manages to feel retro and futuristic all at once.

But don’t let the “party” aesthetic fool you; this bag is built for the long haul. Constructed from a mix of 200D recycled nylon ripstop and 400D recycled nylon, it’s lightweight yet incredibly durable. To ensure your gear stays dry when the sky inevitably opens up, Topo has lined the interior with a 600D polyester non-P PVC coated waterproof truck tarp.

Not only does this keep the rain out, but the bright, easy-to-clean liner also makes it surprisingly simple to find that one stray Allen key or hidden snack at the bottom of the 3L main compartment.

Attaching the bag is a breeze thanks to a sturdy VELCRO® handlebar system that keeps it secure even when the terrain gets rowdy. Across the front, you’ll find daisy chain webbing—perfect for clipping on bike lights, carabiners, or any extra gear that didn’t fit inside.

And when you finally park the bike to explore on foot, the included removable shoulder strap turns the bag into a stylish cross-body carrier, proving that utility shouldn’t stop just because the wheels have.

Priced at just $49, it is a remarkably accessible entry point into the world of premium bike luggage. Perhaps the most impressive aspect, however, is the commitment to the planet. Both brands have prioritized sustainability, utilizing recycled materials and ensuring production processes are WRAP® and Fair Wear certified.

This means the people making your gear are treated with the same respect as the trails you’re riding. Plus, with the MAP Guarantee™ Repairs Program, you know this is a piece of kit designed to survive seasons of abuse, not just a single summer.

It’s roomy enough for a spare layer, a pump, and a cheeseburger, yet compact enough to sit low on your bars without interfering with your GPS mount. If you’re looking to add a bit of personality and a lot of functionality to your ride, this limited-edition stash bag is the “match made in gravel heaven” you’ve been waiting for.
