I'd been searching for a while for pants to wear biking in cool (30-50F) weather and I found them in this product.  Just the right weight to keep me warm (no need for fleece when you're exercising vigorously).  The legs are a bit on the long side, but this isn't a problem when biking.  In fact, the longer legs keep them from snagging on parts of the bike.  Pockets are a nice bonus.  If there's a downside to this product, it's the drawstring.  A cheap dongle or something to cinch the drawstring would make it perfect, but as it is you have to try to tie it in place.
