It’s not just green, it’s Celtics green. The instantly recognizable away shorts of the 17-time NBA Champions, with shamrock logo included, are all the inspiration needed for this Boston boxer brief. Part of our new line of casual NBA underwear, this fitted boxer brief is designed in the latest Del Mar style, with an exposed elastic waistband and Feather-Seam construction. Larry Legend never got the chance to don Celtics underwear, but it’s not hard to imagine the Legend wearing ‘em 24/7 in his prime.
