Over 1 year with this helmet. You'd be hard pressed to find a comparable helmet for the price and very low weight. I use this on race days, typically not for training. No problems with vents, straps or comfort. My one gripe is that my glasses don't slide into the forehead vents. I wear Oakley Radar Paths, and they fit perfectly on my day to day helmet (Giro Ionos). So when I wear the X-Lite and want to put up my shades, they go behind my head. Not a huge deal, but I do wish it fit the oakley earpieces better.
