Compression
Built for muscle engagement and friction-free agility during high-intensity training.
Athletic
Fitted through the chest and taper through the body. The balanced everyday gym standard.

Between two sizes?
For training, sprints, and gym lifting, size down for an aerodynamic feel. For daily wear, lounging, or post-workout layering, choose the larger size.
Compression Gear Dynamics
Our compression tops and tights contain 18% high-grade elastane to actively grip and support muscle groups. If you prefer breathing room, order one size up.
