This is a hooded pullover from MOUNTAIN MARTIAL ARTS. It's the model that Takaya Mitsuya wore. I've used it about 3 times for running. It's in good condition with no noticeable damage. MMA Running Wear 24AW Balaclava Hoodie L/S Long Sleeve T-shirt L -- Flat measurements: Length: 69cm Shoulder width: 51cm Width: 56cm Sleeve length: 69cm -- This monotone collection uses high-performance materials and has a chic and cool atmosphere. This is a new type that combines a long-sleeve T-shirt, which can be used widely from running on chilly days to a base layer for mountain climbing, with a balaclava-style hood. The original Japanese-made body has a relaxed fit with room in the shoulders and chest, and a natural shoulder. The unique balaclava-style hood keeps your neck, ears, and head warm. The sleeves have thumbholes. The back hem is switched with MMA's original pattern printed by sublimation transfer, which does not impair functionality. The hem has slits and a classic detail with a longer back hem. The material uses COOLMAX®, which has excellent moisture absorption and quick-drying properties. -- Type...Running shirt Sleeve...Long sleeve Gender...Unisex Running wear, long sleeve T-shirt, balaclava, hoodie
