Acid Running Long Sleeve T-shirt - Black

About This Piece
The Acid Running Long Sleeve T-Shirt in Black is a technical layer built for cooler runs and high-output sessions. Made from a lightweight blend of recycled polyester and elastane, it helps manage sweat while allowing easy movement. Flatlock seams reduce friction, while thumbholes and a subtle reflective logo add practical finishing touches.

Why We Chose It
We chose this because a dependable long sleeve is useful across changing conditions. Light enough for training, comfortable enough for regular wear, and easy to layer when temperatures drop. The clean design and considered details make it a reliable option for early starts, solo miles, or everyday use.
