| And I am not sure what a camelbak is |
A CamelBak is a sportsing hydration system. Basically it's a bladder/bag with a tube running off the bottom of it that ends in a bite valve. The bladder fits in a backpack and there's a hole in the backpack for the tube to come out and also a 'D' ring to keep the tub close to the wearer's mouth on the backpack shoulder strap. You can run, walk, bike or do whatever it is that you want to do without having to worry about carrying your water bottle in your hand. Most of the backpacks are insulated so your beverage stays cool - and you can even get neoprene tube insulators.
The military have been using camelbaks for a while now, especially when troops are in the desert/middle east.
We've had ours for a few years - Dave got his first, then I got mine, and the kids ones are hand-me-downs from Dave and I. I love mine, I use it as often as I can - even when I'm walking the dog! Because it's basically a backpack with a separate insulated pouch for the bladder I can use it as a sport carry-all - in fact, I used to use it as a purse! I don't carry it often now because I'm carrying knitting and the combination of needles and bags full of water is a bad one. However, this summer it'll get more use, especially when we start going to the pool every day again!
