Made for a muscular build. Finding a tee that fits an athletic body is usually a lose-lose. A medium is too tight in the chest. A large tents at the waist. The i2y4n Muscle Fit is cut broader across the shoulders and chest, then tapers clean so it stays close without hanging like a bag. Why it works Physique-honest fit: Tapered sleeves sit on the biceps instead of flaring. Close through the chest and arms, with enough room through the midsection to stay comfortable all day. Close without the crush: Soft bamboo stretch holds shape like light compression, without that stiff squeezed feel. Moves with you: Four-way stretch for reaching, training, or just living in it. Stays fresher than cotton: Bamboo helps with moisture and odor, so it holds up from a workout to wherever you’re going next. Like a shirt, not a gym costume: The unique bamboo finish works under a jacket or on its own. Gym to street without changing. Specifications & Care Fit: Muscle / athletic (tapered sleeves and waist) Material: 95% bamboo / 5% spandex Care: Machine wash cold. Hang dry to keep the fit.
