Caution: Explosive is not a warning you ignore. It is the baseline for how some people train. If intensity is your default setting and showing up at half speed is not an option, this one fits.This long sleeve tee is built as a comfortable, everyday layer for light training, warm ups, travel days, and long hours when comfort still matters. It wears easily on its own and layers cleanly under a hoodie when temperatures drop. Simple, durable, and steady enough to stay in rotation.This is not a technical performance layer and it is not trying to be one. It is a well built long sleeve tee for athletes who train with purpose, bring energy into every session, and understand that intensity does not need an introduction.Fabric and Fit Notes100 percent airlume combed ring spun cottonHeather colors use a cotton and polyester blendLightweight 4.2 oz fabric suitable for layeringRegular fit with side seamed constructionCrew neck with ribbed cuffs Size guide SHIRT LENGTH (inches) CHEST WIDTH (inches) CHEST TO FIT (inches) SLEEVE LENGTH (inches) XS 27 16 ½ 31-34 25 S 28 18 34-37 25 ⅝ M 29 20 38-41 26 ¼ L 30 22 42-45 26 ⅞ XL 31 24 46-49 27 ½ 2XL 32 26 50-53 28 ⅛ Browse more training gear in the Class 5 Performance collection.
