The Sea to Summit TPU Guide Map Case is a fully waterproof, dustproof map and document carrier built from PVC-free thermoplastic polyurethane (TPU) with a totally welded, stitch-free construction. Rated IPX8, waterproof at 10 meters for one hour, it suits paddlers, wet-weather backpackers, and orienteers who need reliable protection for paper maps, charts, or documents. Three sizes (Small, Medium, and Large) cover a range of standard map and chart formats.
Waterproof Protection You Can Verify
The TPU Guide Map Case meets IPX8 testing standards, meaning it is waterproof at 10 meters for one hour. Every unit is individually tested before it leaves the factory, so the waterproof rating is not a category claim applied to a production run but a confirmation for the specific case in hand. For a paddler running a river section or a backpacker caught in sustained rain, that individual verification matters more than a blanket brand promise.
Built to Stay Flexible in the Field
TPU remains flexible even in extreme cold, so the TPU Guide Map Case can be folded for pocket storage and unfolded repeatedly without cracking or losing clarity. The nylon fabric body and TPU window are also UV-resistant, which prevents the yellowing and brittleness that shortens the life of PVC map cases used in high-sun environments. A map case that stays clear and pliable after a full season of use is one that does not need replacing mid-trip.
Attachment Options for Moving Systems
Corner anchor points on the TPU Guide Map Case allow it to be clipped or lashed to a deck bag, pack shoulder strap, or handlebar bag without improvising a mount. The included neck strap is detachable, so it can be removed when the case is clipped in place and reattached when a hands-free carry is more practical. Both options keep the map accessible without requiring the case to be stowed.

Who This Is For and Isn't
The TPU Guide Map Case suits paddlers, wet-weather backpackers, and orienteers who carry paper maps or charts and need a case that is individually verified waterproof, stays flexible in cold conditions, and can be clipped or worn hands-free. All three sizes work for standard folded maps and navigation charts.
The case is designed for flat documents and maps, not for smartphones or tablets; no device-specific cutouts, touch-through windows, or charging ports are present. It is a flexible soft case and does not provide impact protection for electronics.
Common Questions
What is the waterproof rating of the TPU Guide Map Case?
The Sea to Summit TPU Guide Map Case meets IPX8 testing standards, meaning it is waterproof at 10 meters for one hour. Each individual unit is tested before shipping, so the rating applies to the specific case rather than to the product line as a whole.
Will the case crack or stiffen in cold weather?
The TPU Guide Map Case is freeze-proof. The PVC-free thermoplastic polyurethane material remains flexible in extreme cold and can be folded for pocket storage repeatedly without cracking or discoloring, making it suitable for winter paddling and cold-weather backpacking.
How does the case attach to gear?
The TPU Guide Map Case includes corner anchor points for clipping or lashing to a pack, deck bag, or handlebar bag, and a detachable neck strap for hands-free carry. The neck strap removes when the case is clipped in place and stored separately.
Which size should I choose?
The Small measures 8 × 11 inches, the Medium 11 × 12 inches, and the Large 13 × 16 inches. Choose based on the folded dimensions of the map or chart you carry most often. The Small suits standard folded trail maps; the Large accommodates full nautical or topo chart sheets.
