I just ordered a Kriega Hydro-3 to replace my Camelbak hydration pack. The new style reservoir on the Camelbak is better than the old one but I think the Kriega will be better yet. Easier to fill, clean(which is a pain on the CB) and the extra liter will come in handy this summer.
I may order a US-5 to go along with it later.
If it ain't fun, I don't do it!!!
