Camelbak water bottles, are they worth the price?

I think if it keeps your water cold, it is worth it for the horseback riding. Keep in mind it will keep things hot also for those cold winter rides. I used to keep a (hot/cold) bottle when i used to ride also.I would keep hot soup in it sometime. Stainless is the best way to go, it will last a lifetime and beyond. You made a good investment.
