I won a Sew Fly in a raffle.

They have generic models like mine, with solid colors and what's probably a synthetic leather -- but I can't tell. They specialize in being able to rip out knee pads with whatever custom materials and patches you supply them with. Like these (SewFly Facebook page).
Now that I have one, I've become more and more attenuated to the fact that even on dry days there are places you can get soggy knees or worse if you don't have a kneepad or towel. The knee pad-cushion seems to work better than a towel.
The reason they are patentable is because they are aerodynamic knee pads -- an original design. Its soft and aerodynamic properties make them great for hard, fast, indoor practice.
I got the Second Life character Little Gray interested in it and he, or she, or whatever it is started making animated cartoon video ad for a SewFly knock-off (best viewed in HD).
That got me thinking, are there other manufactures of knee pads designed specifically for disc golf? I'm working slowly on a product review about SewFlys and was hoping I could compare them to something, or alternatively, be able to say with more authority they are incomparable.
