The Nalgene

How has Nalgene become such a huge name in heavy duty water bottles? I have worked in wilderness camping for a couple years and yes they are great for camping. Also they are great at times when I am treeplanting, but really $10 bucks for a one liter water bottle? I do admit Nalgenes are basically indestructible other than their very weak lid to bottle strap. One reason may be that Nalgene, until recently, did not really have very much for competition in the high strength water bottle market. I suppose they must be good seeing that they have sold millions of their little plastic bottles.
