Aquapac Kaituna Waterproof Map Case
When students ask me ‘What is the most important piece of navigation kit you carry?’ My answer is always the same, my map. Therefore, I am really careful in looking after this vital piece of kit, from folding it correctly to protecting it from damage and most of all, getting wet.
There are lots of waterproof map cases out there, but how do you know it is going to be waterproof, many of us remember the manufacturer’s claim that the Satmap (GPS) was waterproof, only to end up having to send them back when they had been used in the wet!
The good news is that there is an international standard () for the Degrees of ‘Protection Provided by Enclosures’ and it is called the IP Rating. It consists of the letters IP followed by two digits. The first digit represents the level of protection against solid objects (an X is used if this protection is not measured) and the second last digit is the waterproof protection.
Aquapac Kaituna Waterproof Map Cases have the highest rating for wet weather protection IPX6.
The Aquapac Waterproof Map Case fits both Ordnance survey Landranger (1:50 000) and Explorer (1:25 000) maps plus Trail Magazine Illustrated, Harveys, and Michelin maps for use abroad.

In common with most national mapping agencies all Ordnance Survey maps fold the same way with pre-pressed creases. To fold a completely unfolded map follow this guide:
