Great glasses
I wear my Intensity glasses year round - road cycling and mountain biking in the summer and Nordic skiing and snowshoeing in the winter. The sunshine and cloud cover can change quickly but with my Intensity KJs I’m always prepared.

Super light glasses
These are great for road and trail running! My 2nd pair, purchased the Orange Intensity’s for the 0-3 photochromatic lens for trail runs under tree cover. These special edition KJ’s have slightly darker lens good for brighter days. The design fits me very well and are extremely light,
noticeably more so than Oakley Sutro Lite and District Vision Speedblade which I also. For race days I have been going with the Julbo’s due to their comfort, lighter weight!
