Sea To Summit Guide TPU Map Case

The Sea to Summit Guide TPU Map Case is a waterproof pouch for paper maps, built from welded TPU with a roll-top closure rated IPX8 for submersion to 10 m. The transparent front lets you read the map and use a touchscreen through the material without opening the case, useful for checking a phone GPS alongside a paper map in the rain. It comes in two sizes to fit different map or guidebook formats. This is a protective case rather than a navigation tool itself — it suits hikers who still carry paper maps as a backup or primary reference and want them to survive a river crossing or a downpour; it will not help if the map itself is lost or left behind.
