Four-Way Stretch. Lightweight. Built to Train.

The Muscle Nation Climaflex Active Tee in Dark Khaki is a fitted performance tee designed for training, lifting and high-movement sessions.

Made from Climaflex polyester jersey with four-way stretch, it delivers a body-contoured fit while still allowing unrestricted movement. Side splits at the hem help improve mobility, while the lightweight, easy-care construction makes it practical for regular training.

A classic crew neckline, standard tee length and subtle Muscle Nation branding complete the performance-focused design.

Fit and feel

Muscle Nation lists the Climaflex Active Tee as true to size with a fitted cut.

If you prefer a more regular fit rather than the body-contoured silhouette, Muscle Nation recommends sizing up.

The four-way stretch fabric gives it more freedom of movement than a standard cotton tee, making it especially suited to lifting and functional training.
