Great snorkel set, not sure about "fancy" features though

The mask and snorkel fit comfortably, although the neoprene "SnorkelSystem" strap slid down my head a bit while wearing. I think the plain mask straps would have stayed in place better without the fancy cover, but then there was no way to attache the snorkel and hold it upright, so I couldn't just take it off.
I really liked having the one way valve to breath out of my nose and that worked well. The dry-top snorkel was nice, but certainly not perfect. It still let in a little water now and then, and I question if it is really worth it.
