Small Packs Of Tissues
Take handy packs of tissues, the ones that come in waterproof packaging and fit in your pocket.
Loo roll often ends up getting wet somehow, especially if it’s chucking it down and your bag or tent isn’t very waterproof.
Also, if you’re a boy, and you take toilet roll with you to a portaloo, everyone pretty much knows you’re going for a poo.
It’s obvs.
