When I was in Wales the other week I bought a drinking tube kit for my roll up, 1l Platypus bottle. I have a Camelbak water bladder but I have had trouble with it going mouldy between trips – even though I have a Camelbak cleaning kit and hanger, which I use and I take care when drying it out. I now store the Camelbak with water in it and the air squeezed out. On the other hand I I have had no trouble with the roll up Platypus bottle – again I take care to dry it out before storing it away. The drinking tube kit will convert any Platypus roll up bottle into a bladder system – I can use it as a drinking system whilst on the trail and easily use it as a water bottle at the campsite.
Next month I am planning a wild camping trip to The Old Man of Coniston – when I will need to carry the water I will need for overnight – so I have bought another Platypus, a 2l version for extra water storage.
Here it is stored in my GoLite Jam backpack.
