Have owned 5 pairs of Kaenons (Jetty, Lewi, Klay, UPD, and Hard Kore) and the Jettys are my all around favorites. They are very light and pretty big, offering good coverage with tall frames at the sides which block peripheral light well.
The Lewis are even a bit larger than the Jettys and take the nod for fishing, but the Jettys strike a better all around balance of size and weight.
The Jettys are extremely comfortable and work well for active pursuits. I've never had issues with mine slipping or threatening to fall off (the tips of the arms are also thin enough to use with a croakie strap, which isn't the case with all Kaenon models).
Kaenon's lenses are tops: superb polarization that provides great contrast and clarity. My favorite lens is the C12 (copper), which provides superb color contrast and is really comfortable on the eyes. The gray lenses are darker if you're in really bright conditions all the time, but I like the C12 as the better all purpose lens.
The Jettys are awesome: comfortable, superb polarization, stylish, and they stay in place.
