Even in the modern age of GPS reliance, it's best to have a handy map and compass for back-up navigation when you're trekking over rugged stretches of wilderness and paddling along wandering coastlines and backwoods waterways. Keep your topographic maps and nautical charts safely stored and protected with the SealLine HP Map Case. This waterproof case is available in three different sizes for all your navigational needs, regardless if you're carrying a small day use map or something more extensive for hardcore expeditions. The welded seams and hook-and-loop secured roll-up closure prevents water from seeping inside, even if you accidentally drop the map in the wet kayak cockpit or open lake. It comes with an adjustable neck strap for convenient use while paddling, as well as four tie-down points for tethering it to the front of your vessel.
