Who doesn't measure their water??

I was recklessly pouring water into my hiking food without any real idea of how much was going in. Since buying my Nalgene I'm now able to be much more precise thanks to the built in increments on the side of the bottle. This also helps reduce water wastage when out bush. My advice is to get a lighter colour bottle as its easier to read measurements on. Happy water consumption!

Such an outstanding idea and alternative to using a water bladder

So light and the perfect size - a decent size to drink out of without being too big or small.

No-nonsense workhorse

Been looking for a decent torch as a secondary light source for searches and hikes. Wondered why, given the thousands of offerings out there, Past stocked only this one. Well, Dave recommends it so it must be half decent. Turns out it is. Super bright. All the modes you need, none you don’t. Solid construction. Light and reliable. Rechargeable. Done deal.
