Sea To Summit TPU Accessory Case


Waterproof TPU Accessory Case – Small / Medium / Large

Electronics, dry. Confidence, high.

Whether you're navigating a river crossing, riding in sideways rain, or just want peace of mind with your essentials, this TPU Waterproof Accessory Case has your back.

Perfect for keeping your phone, maps, passport, or trail permits dry and accessible, the case features die-cut anchor points, a neck strap, and a clever construction that lets you use your touchscreen without removing your device.

About Us

Though we’re a bike shop that sells, builds and fixes bicycles, they’re really just the means to an end; albeit a beautifully designed means to an idyllic end. Our job most importantly is to encourage as many people as we can to get out and ride for transport and enjoyment. We'd love to make riding a bike as commonplace as your morning cup of coffee, which by the way is our other obsession.
