Lululemon Men’s Kahuna Black/Blue/White Plaid Shorts SZ 36

Lululemon Men’s Kahuna Black/White/Blue Plaid Shorts size 36. There is a stain on the back about 3/4 of the way to the bottom. Not sure if you could get it to come out or not - it feels like sticky residue of some kind. Price reflects. Otherwise in very good used condition and from a smoke-free home.
