Don't let the cold sideline your performance. The Optimum Sideline Sub Jacket is the ultimate pitch-side essential, engineered to lock in core body heat and block out biting windchill while you wait for your moment. This long-length, quilted coverall is a heavy-duty alternative to the classic sub suit, providing superior thermal protection for athletes across all disciplines — from football and rugby to swimming and athletics. Designed for all-weather reliability, it means that when the coach calls your name, you step onto the field warm, limber and ready for action. THERMAL QUILTED PROTECTION: Stay game-ready in sub-zero conditions. A 4oz quilted waterproof nylon construction provides a thick, insulated barrier against the elements without feeling overly heavy. WINDPROOF & WATERPROOF: Defy the British weather. The rugged waterproof nylon outer shell is designed to keep the rain out and deflect the wind, keeping you dry and shielded during long stints on the bench or poolside. HASSLE-FREE HOOK & LOOP FASTENING: Make your entrance in seconds. A full-length hook-and-loop fastening system replaces traditional zips, allowing for a fast rip-off transition when it's time to sub in. INTEGRATED WARMTH FEATURES: Every detail counts. A stand collar seals out draughts, two deep outer pockets keep hands warm, and adjustable wrist straps let you customise the fit and trap heat. VERSATILE MULTI-SPORT USE: One jacket, every sideline. Whether you're a footballer waiting on the touchline, a swimmer staying warm between heats, or a coach managing the squad, this over-jacket is built for sideline comfort. INCLUSIVE SIZING (MINI TO XXL): The whole squad covered. Available in a wide size range from Junior Mini through to Senior XXL, for youth teams and adult players alike. What sizes does the jacket come in? It's available from Junior Mini through to Senior XXL.
