Stumbled across this one quite by accident today, in one of those wacky Aldi grocery stores. A camelback clone for .00. It's a 'special' until 7th January, and as usual with Aldi, the shop I went to (Hornsby) only had two items left, and one was incomplete, so YMMV :-) Still, worth a look methinks. I bought one. Seems OK. I'll give it a try tomorra whilst out on a ride. Removeable bladder that seems to be a reasonably heavy cinyl, holds 2 litres, a tube that can run up the inside of the shoulder strap on either side, a push/pull tap and a bite'n'suck (woo!) mouthpiece thingami. Room in the backpack for a bit of other stuff too. [URL]http://australia.aldi.com/cms/product_03/product_117.html[/URL] G
