Frontline Long Sleeve Base Layer
Engineered for performance. Built as your first line of defence.
The Frontline Long Sleeve Base Layer provides essential support for athletes who train in demanding conditions. Designed as a high-performance foundation layer, it delivers reliable moisture control, temperature regulation, and unrestricted movement during training and everyday activity.
Constructed from recycled performance fabric, this base layer features advanced moisture-wicking technology that pulls sweat away from the skin while quick-drying properties help maintain comfort during intense sessions.
The four-way stretch fabric moves naturally with your body, providing unrestricted flexibility whether you're running, lifting, cycling, or training outdoors. A slim ergonomic fit sits close to the body without excess material, creating a streamlined silhouette that layers easily under hoodies, jackets, or training tops.
Flatlock stitched seams reduce friction and eliminate irritation commonly caused by traditional seams, making the garment suitable for longer sessions and endurance training. A tear-out label further improves comfort by removing potential irritation points.
Designed to regulate temperature and manage moisture, the Frontline Long Sleeve Base Layer works as a reliable foundation piece within your training kit, delivering comfort, mobility, and performance when you need it most.
Built with the Frontline mindset — performance, durability, and disciplined design.
