The socks (and tshirt) were from last year's set up. The uni's last year had the SJ logo, based in it being an alum team of 30+ year olds some guys wore that logo. Hearing that Mikey Powell may be pulling double duty and join the Burnt Orange this year.
Not sure the shorts will be available for purchase, try reaching out to the guys (Steve Panerelli) at Reversible Lifestyle.
