I may have reviewed this before, but since Ive been using it a while and love it, heres an update. This is excellent lube, and as its name kind of implies, can be used in wet or dry conditions. Its pretty good in winter at not accumulating too much grit, and lasts about 100 miles or more, depending on weather. In dry conditions, its lasts much longer. The lubrication is top notch you can seriously tell the difference when you reapply.
I know some will knock the price, but Ive used various cheaper lubes, and hydrodynamic is just superior.
