Because of my work I often commute on bicycle for long distance; my longest days have me in saddle for 50+ miles a day. I enjoy Skratch hydration mix more than any other brand because there is no conspicuous artificial taste with any of their flavors. I like they taste naturally lemon-y, naturally pineapple-y, naturally strawberry.
Just a plug for the unsweetened version of the hydration mix as well.
