There is a moment in training when a sequence starts to make sense and you want to try it once more. That is the time on the mat you choose your gear for. Hardcore Training Koi Black brings an individual look to your BJJ and MMA sessions, for men who want their training kit to feel like their own.
The Koi Black print gives this rash guard its character among the gear you reach for before class. Whether you are learning your first techniques or returning for familiar rounds with a partner, it belongs in the part of your day devoted to martial arts. Wear it as your no gi top or beneath a gi jacket, then get back to the practice you came for.
- Ready for your next round: Koi Black pairs a fitted cut for men with long sleeves for BJJ, MMA and grappling. From partner drills to rolling, the rash guard stays close to your body without the loose folds of an everyday T-shirt.
- Quick-drying stretch for training: The 88% polyester and 12% spandex fabric follows reaches, turns and changes of position. Its second skin fit gives you a flexible training layer from the warm-up through your final round.
- Grip at the lower edge: A silicone band inside the hem helps hold the rash guard in place as you change position. Flat seams join the fabric panels without bulky ridges, keeping the construction low profile against the body.
- A print made for repeat sessions: The Koi Black design is sublimated into the fabric, giving the shirt its distinctive look. Its colors hold through washing when the care instructions are followed, ready for regular training.
- Find your fit and care for it: Compare the garment measurements with a rash guard that fits you well. Machine wash at 20–30 °C and keep open hook and loop fasteners or other snagging items away from the fabric during washing.
