hello all,
I am sure a couple of you do mountain biking and I'd like to what type of camelbak you guys use. Which would you recommand

I want to buy one from ebay but I don't know much what to "check"
Not an obligation to be from camelbak brand

Well I've used a Camelbak on several occasions. I can't recommend a particular model, I just know it held about 2-2 1/2 liters of water and had alot of packing space (I had enough for 3 days worth of clothes plus other items).

I would try and go to an outdoors store and see which fits best for you. I know Camelbaks are a little more because of the name (their quality is top as well, though) so you might be able to find a cheaper alternative. I'll try to find a model number or name for you this weekend.

Mountain bike review site has a lot of models reviewed so I can pick one and go in a local store

I dont know yet
