Where Fit Meets Function

Where Fit Meets Function

Born on the Climb

Gibraltar Bag Co. was founded by Trevor, an avid mountain biker based in Santa Barbara, California. With a background in sewing and design, he started building custom-fit bags to match the exact geometry of his own bike for bike-packing trips and everyday rides.

Named after Gibraltar Road, each bag is built with care and designed to ride as hard as you do.

How It Works

  • If you're local to Santa Barbara, meet with Trevor so he can measure your frame and see your setup in person.

  • Talk through your riding style, storage needs, and fabric preferences to create a bag that fits your bike and your ride.

  • Your custom bag is handcrafted to match your frame perfectly and built to perform on the trail.
