Riding up on the Pemberton Icecap 3-4 times a week at this time of year my eyes would get fried from the sun and reflection off the snow. I was using Bolle goggles which had the darkest lens I could find but wanted something easier on the eyes. When I saw the 509 had a polarized lens I asked Tom if he could send me out a pair to try out. Tom was nice enough to send me out a set and I got them about 10 days later which is pretty good for mail across the border. I was quite impressed with the quality of the frame and lens of the 509’s. The band actually sticks to the helmet and doesn’t slide down the back of it. The polarized lens really works well up on the glaciers. No more glare and they are much easier on the eyes. I put the nose shield on just to see how it fits and was going to take it off. I forgot to and am glad I did, we had some pretty cold winds a couple of weeks ago and the shield also helps your nose from getting burned off from the sun. The wide foam makes these goggles very comfortable to wear. Two thumbs for the 509’s
