OS Dry Bag 25 litre

Protect your kit with these waterproof dry bags from Ordnance Survey.

An ideal companion for any outdoor activities where you are at the mercy of the fickle British weather. This waterproof dry bag can be used inside a rucksack or on its own, using it's handy adjustable carrying strap.

Its 25 litre capacity gives enough room for a couple of maps, a mobile phone, a jumper, a wallet, extra socks, and still leaves space for a few more essential items. It also keeps water in, ideal for keeping muddy dog towels, wet trousers, or soaked hats away from the rest of your gear.

It's made from a tough ripstop nylon with taped seams. To seal, simply fold over the top two or three times and clip the buckles together.
