Camelbak 2L Hydration Bladder tastes of water, 02 September 2011
By Ross (UK)
I thought long and hard about which model to go for, chose this one for a number of reasons.
Size: 2 litres and a flask of tea covers most of the walking requirements until you get above the 6 to 8 hour mark in which case the 3 L is a must.
The bight valve is great and as advertised, does not leak. Except when I've trapped the bitevalve between my back and rucksack to get soaking from the waist down when the bitevalve opens.
However the tap solves this problem providing you get into the habit of closing it after use.
The large opening filler cap gives easy filling and cleaning options which together with the moulded handle make the operation easy. The large screw cap and seal prevents leaks.
It's true the water is not tainted and is completely palatable.
Outer case: despite a small weight disadvantage, the cover gives physical protection to the bladder and an element of insulation on winter days.
The hanging strap is a feature I have not used and that is also the case with the straps on the body of the pack but it looks as if these could be attached to a harness of some sort and used directly on the back like a mini hydration pack.
All in all a great unit, very happy with the purchase

I have owned a couple of hydration systems in the past and always tried to go 'cheap' thinking they were all the 'same'. What can go wrong with a bladder that holds water with a tube to drink from while on the move? Easy! Well, I couldn't be more wrong. Like with any other outdoor kit its best to buy quality. My last hydration system had a 'plastic' taste no matter how much I washed and re-fridgerated it.
The Camelbak out of the box was perfect. Even giving it the first rinse as advised I had to have a sip to see if the taste was tainted and it wasn't.. perfect!
On checking it over after purchase I rmeoved the bladder (mine is the 2ltr) and it looked a decent size and I wondered how comfortable it would be. I was suprised by how comfortable it was while hiking and climbing. Also the outer does help keep the bladder cool and even when its been on my back for 8+ hours it still manages to stay cool, drinkable... this means I will drink and wont dehydrate.
The bite valve it brilliant too, it has a tap that you can shut off but I leave mine open so that its really easy to just bite the valve ans drink on the move. Even with that tap open the bitevalve is fine and wont leak.
I would highly recommend this as a product, if I lost mine tomorrow I'd buy one again. The only negative I can think of is that it didnt come with a yoke system so that I could use it alone without putting it in my daysack. For runners they could benefit from a yoke system so they can strap it to theirs backs and away they go. Pretty sure you can purchase these seperately but for the price, its a quality product and I am really searching hard to fault it.
