Sea to Summit TPU Accessory Case

The Sea to Summit TPU Accessory Case is a lightweight, waterproof soft pouch built for paddlers, backpackers, and travelers who need reliable protection for phones, cards, and small accessories in wet or dusty conditions. Constructed from nylon fabric with a TPU window and sealed with a roll-top closure, the case meets IPX8 testing standards, waterproof at 10 meters for one hour when properly closed. Three sizes (Small, Medium, and Large) are available to suit everything from a credit card stack to a full-size smartphone.

Waterproof Where It Counts

The roll-top closure with double hook-and-loop fastener creates a watertight seal that keeps water and dust out during river crossings, rain-soaked approaches, and paddling trips. The case meets IPX8 testing standards, meaning it has been tested at a water pressure equivalent to 10 meters depth for up to one hour when properly closed. Sea to Summit notes that IPX8 certification is not a guarantee for an electronic device stored inside, and the case is not designed for intentional submersion. For incidental water exposure on trail or water, the seal performs.

Flexible Enough to Live in a Pocket

The PVC-free TPU window and nylon fabric construction stay pliable even in extreme cold, so the case can be folded flat for pocket storage repeatedly without cracking or discoloring. That flexibility matters on multi-day trips where gear gets stuffed and unstuffed constantly. The case holds its integrity without becoming brittle or stiff in alpine or winter conditions.

Touch-Screen Compatible and Ready to Clip In

The TPU window material allows touch-screen devices to operate inside the case, so navigation apps, music controls, and camera functions remain accessible without breaking the waterproof seal. Top corner anchor points accept a cord or carabiner for clipping to a pack, kayak deck line, or belt loop, and a neck strap is included for hands-free carry on the water or trail.

Specifications

Who This Is For and Isn't

The Sea to Summit TPU Accessory Case suits paddlers, backpackers, and travelers who need a lightweight, packable way to protect a phone, cards, cash, or small accessories from water, dust, and cold. The touch-screen-compatible window and anchor points make it practical for active use on the water or trail, not just storage.

The case is not a rigid hard case and does not provide impact or crush protection. IPX8 waterproof performance applies only when the roll-top closure is properly sealed; the case is not designed for intentional submersion. It does not replace a purpose-built waterproof phone case rated for diving or sustained underwater use.

Common Questions

Can I use my phone's touch screen while it's inside the case?

Yes. The Sea to Summit TPU Accessory Case uses a TPU window material that is touch-screen compatible, so a phone's display and touch functions remain usable without opening the case or breaking the waterproof seal.

Is the case waterproof enough to protect a phone during a river crossing or kayak trip?

The TPU Accessory Case meets IPX8 testing standards, tested at a pressure equivalent to 10 meters depth for up to one hour when the roll-top closure is properly sealed. IPX8 certification is not a guarantee for the electronic device inside, and the case is not designed for intentional submersion, but it is built to handle incidental water exposure during paddling and wet-weather use.

Will the case crack or stiffen in cold weather?

No. The PVC-free TPU material used in the Sea to Summit TPU Accessory Case is rated freezeproof and remains flexible in extreme cold, so it can be folded for pocket storage repeatedly without cracking or discoloring.

What is included with the case?

Each Sea to Summit TPU Accessory Case includes a neck strap. Top corner anchor points on the case accept a cord or carabiner (not included) for clipping to a pack or kayak deck line.

Which size should I choose?

The Small (approximately 4 × 5 in) fits cards, cash, and compact items. The Medium (approximately 5 × 9 in) accommodates most smartphones. The Large (approximately 6 × 8 in) suits larger phones or groupings of small accessories. Refer to the Specifications table for exact dimensions before selecting.
