Read and submit reviews for the HydroSkin Shorts.
On the inside, though, I've had some issues. I find that, when rotating, the inside of the shorts sometimes rub me raw on my back-side (i.e., rubs the skin completely off). This is uncomfortable, to say the least. I try to prevent it by using tape across my backside, inside the shorts. I don't know if this is a problem with this particular fabric, or if it would happen with just about any fabric -- just don't know.
Overall, I'm pretty happy with these. Though as I said, for colder conditions, more coverage would be desirable. If I lived in FL or some other warm climate (I don't -- I live in MI), I might use something like the McNie Kayak Short -- or perhaps a longer pant tights of some sort.
