If you spend much time riding with eye protection – as you should – you’ve been there: rolling up to a big drop, making your move on a technical climb, or sprinting for the finish in the peloton, your glasses fog up and you blow it because you can’t see a thing. Crap. Or, more specifically, Cat Crap.

As unrefined and vulgar as it may sound, EK Cat Crap lens treatment is the solution. Packaged in a small, pop-top container this blue paste, thankfully, doesn’t contain any . . . uh . . . feline remnants. Instead, it’s a mix of anti-fogging, cleaning, and wax agents that, when applied, clean your eyewear lenses and prevent fogging.

The paste is applied with a fingertip, allowed to dry to a haze over a one or two minute period, then buffed clear with a soft cloth. Not only does that process get your lenses beautifully clean, it also prevents fogging and repels lint and dirt. Perhaps it’s my imagination, but my glasses also seem to shed sweat better when they’ve been freshly treated with Cat Crap.

Aside from pointing out that the product works best when applied just before you head out the door for a ride, the only thing to say is that it works! Fogging due to humidity, sweat, and exertion is virtually eliminated, while the lens stay cleaner longer. As mentioned before, my biggest issue with eyewear is that the lenses get covered in sweat, the sweat dries, and my vision is obscured. But Cat Crap even seems to improve the way lenses shed sweat and water.

A container of Cat Crap costs about $6.00 and will last for 6 months or longer, even if used daily. EK recently introduced a spray version of the product, which costs slightly more but is supposed to be just as effective as the original paste, though I haven’t tried it.

I have at least half-a-dozen containers of the paste hidden in my cycling gear and consider it to be almost as important as water, spare tubes, and chain lube. If you doubt that statement, you’ve likely not had the pleasure of trying to ride a technical mountain bike trail after a summer rain with fogged sports glasses.

Many bike shops and outdoor stores – including dive shops – carry Cat Crap, or it can be ordered online. If you can’t find it locally, ask for it by name. If nothing else, it will make for an excellent conversation!
