John O'Callaghan, also known for OC Studios and OC Blades, is a custom knife maker and photographer based out of the San Diego area. He's a purebred New Yorker, where he worked as a crane rigger and mechanic to put himself through art school. Getting his start apprenticing for the Navy Seal run Half Face Blades, John quickly learned the craft of knife making and began creating blades in his own style soon after. In and out of the water, John can be caught with camera in hand shooting anything from ocean movement to street portraits of Hollywood's elite. A bit of a jack of all trades, John embodies the saying "be too complex to categorize."

WAIST MEASUREMENT - Use a measuring tape to measure around your waistline, just above the top of the hip bones. Make sure the tape is snug but not too tight.
INSEAM LENGTH - Grab a pair of pants that fit well and lay them flat on the floor. With a measuring tape, measure the length from the crotch to the bottom of the leg/hem.
Our hoodies, shirts and tees have a generous tradesman fit and are slightly longer in length than you may be used to, preventing any unwanted exposure.
