If you carry a Water Bottle, it Should be Stainless Steel!
SS definitely has its place,but other types of water bottles have their place as well. For cheap and light, recycle a beverage bottle, preferably one with a wide mouth.For compact and lightweight, use a flexible Platypus or Nalgene. For large loads of two gallons or more, plastic rules. I can't recall ever damaging any bottle to the point where it couldn't be used. Down here in the arid southwest, two or more,perhaps of different types,make a lot of sense.
