http://www.aerotechdesigns.comI found them just surfing the web for cheap Bike shorts WAY back when I started biking. have since gone and purchased "fancier" shorts but in the long run,.. I still prefer these!! and they were a mess cheaper.
I have purchased the basic no frills pad and the fancy contoured pad from here and love them both!! Thinking tights might be next
check it out.. buy a pair. you'll probably never buy the name brands again.
