Equip, Inc. Protective Cover for Rowing Machines. Heavy Duty UV/Mold/Mildew/Water-Resistant/Indoor and Outdoor Cover

The ad actually has a photograph of a grey Concept 2 machine so it certainly isn't a stretch of the imagination to believe it should fit that machine well.It doesn't.The cover is much too big and the machine gets lost inside of it. That's a bit of a problem because the poor fit creates pockets and creases where water and dirt will collect. One workaround I used was to order a pair of aerobic steps that I sit the rower on at each end. This raises it about 6 inches. This allows the cover to drape over the machine much better and gets the machine up so air can circulate under it to discourage mildew and dampness.Lastly, the zipper on this case does not have a weather stirip behind it. It would have been easy to sew a strip of the material behind the zipper so when the two sides come together you would have additional weather/water insulation. Instead the two sides just zip together and when you hold the zippered sides up you can see light coming through...and therefore rain can make its way inside. The zipper runs vertically up the left side so it isn't directly over the machine, but a weather strip should have been included for the integrity of the weatherproofing especially at this price point.Its well made and my first day we had a pretty heavy rain but my rower remained dry. You will need to keep lubricant on all the metal parts, but this cover appears to allow you to keep your rower outdoors. I'll check back after a few months. if there are any problems.

Might fit the Concept 3 D, with tilt down read out panel, but it just hangs like a formless tent on the Concept 3 E that has a fixed read out panel.

Doesn't really fit a Concept 2 Rower very well. It's way to big and baggy.
