Front: Octavio was working with a designer (a student he took from day 1 until almost-black) on a logo before he passed. Sadly, it was never finalized, but this is one of the early prototypes of the design he had in mind. Reflecting the colors of all belts was important to Octavio, as were his students. Back: This design was lovingly created by a long-time student of Octavio's. Sleeves: They contain a reminder that Brazilian jiu jitsu is "the most dynamic way" "to meditate" Don't be afraid to be your most active self in this smooth and versatile long-sleeve rash guard!
