They’re certainly old Bike jockstraps. I’m assuming they have an enormous stockpile because the waistbands don’t match those of the new Bikes. I’m very jealous.
The shots of Boris seemed to get you guys going so here are a few more shots where you can see his pouch slip out of his shorts (and one of his straps from up the leg!), and one of his amazing ass.
Here are a few from Sean Avery, one of my favorite jockstrap wearing athletes. He’s definitely passionate about them. Apparently he wore the swimmers jock to a pool at a resort. Love a man that loves his Bike jocks that much.
