The goggles are great with open face helmets. Bad in winter they do tend to mist up a fair bit. Get the goggles with the centre nut for better fitting as they can be adjusted. make sure your open face helmet has a stud fastening loop at the back as riding with your goggles on top of your helmet occassionaly they will slip off the top of your helmet. Field of vision is excellent. Only downside is that the elastic strap will eventually start to give way but its cheap and easy to replace.
One major problem be to careful of is when pulling away from face to put on top of helmet. Do not let go as they tend to spring back painfully.....just dont ask how I know this.
