I have a pair of baggy 3X mountain bike shorts from Aerotech Designs. These are the Outlaw Bullet Mountain Bike shorts with the chamois pad built in. I may have worn them one time over the summer, but like the road bike spandex style better, so even if I did use them, it was only for one 2 or 3 mile ride.

I am looking for a 3X light weight outer jacket. Something I can use as a top layer over my jersey and fleece to ride in winter. I am currently using a windproof golf jacket, but it doesn't breathe at all, so I need something to let the sweat out. If the jacket runs small, I may need a 4X (i.e. probably any of the Italian brands). It has been a while since I've measured my chest but guessing in the area of 54"; 44" waist.
