I highly doubt that's a wintec. Unless it's a REALLY old version. It's obviously synthetic and the seller *may* be under the impression it's a wintec. As has been pointed out, it doesn't have the logo on the stirrupleather keepers. I've never seen a channel looking like that in the new style or old style wintecs, and also, it doesn't appear to have a label. All wintec saddles have a label, with the serial number on the underside of the saddle flap - just above the girth points. Of course, they only show the right side of the saddle, and the label is always on the left side.
It is not 'cool' to ride without a helmet! period.
