OEX Drysac 2

Small things suffer most in a wet rucksack — phones, wallets, matches — and the 2-litre OEX Drysac exists to protect exactly those. The roll-top closure seals gear away from heavy rain, while the high-visibility lime colour makes the little bag instantly findable in a dark pack or tent. Keep it for electronics, first aid or spare socks; just remember it is built for rain protection, not submersion.
