I'm really happy with these goggles. I have contacts so I need something that has some air flow so my contacts don't dry up. I'm used to having to flip goggles up onto my forehead between runs, but I left these on all day no problem and even forgot they were there. They are very comfortable and didn't fog up at all. Also, great peripheral vision on these. I got the rose lenses, which are supposed to be good in the widest variety of conditions. I have had them out on a day that went from very sunny into a snowstorm and they were great. The band is not one continuous loop. It has a plastic clip which doesn't seem like it would be super strong, but i've wiped out a number of times and never lost the googles. The clip does make it easy to take them on and off.
Overall, great price, very comfortable, great peripheral vision, and amazing with contacts, especially if you have trouble wearing contacts for extended periods of time.
