2 pairs, 6 years, and counting
I'm on my second pair of Fuses now, the first having lasted about four seasons before the face foam started disintegrating completely. I picked up another pair last year, and I've put 120+ days on them the last two seasons and still going strong. I'm out working whether its 30 below, 25 and bluebird, or 40 and raining, and these goggles haven't let me down. Fogging isn't a problem as long as you do what you're supposed to (don't stick them on your head when you're sweating, and once you're outside put them on and don't take them off ever), and fit is great over a hat or with the various Boeri and Giro helmets I've worn them with (big nose, big head, medium-size face otherwise). I wear these goggles every day, swapping between the Platinum Mirror lens for brighter conditions and the Sensor Mirror for boxed in or flat light, with clear lenses for night riding. Both the Platinum and Sensor lenses perform wonderfully, with enough overlap that I can put one in in the morning and be OK even if the conditions change during the day. The Sensor in particular really makes everything pop in flat light. All around, these goggles are a great purchase, especially if you find them at half price on steepandcheap or tramdock at the end of the season.
