Hydration Packs??

That's the one I was going to go for!!!

Like the look of it!

Found a right bargain on the Camelbak though!!

I got a Camelbak Mule about 10 years ago. While it's faded a little, there is not a broken stitch on it. A top quality bit of kit, which looks as though it will go on another 10.

I bought on of the Tesco 1.5ltr ones for £12. Fits really well, but I did run out of water after about an hour and a half... that could have something to do with me being middle-aged and fat though

Not a lot of extra storage, but hardly even notice it's there.
