M-SIENNA Cap
M-Series Seasonal
The FRACTEL M-Series Cap is built for long runs, high heat, and pushing the pace. Designed with our new Airline Mesh™ fabric, this Cap delivers enhanced breathability, quick-drying performance and all-day comfort, without compromising on style or sustainability.
Made from 100% recycled yarns, the M-Series features a structured front panel, pliable peak and moisture-wicking sweatband, engineered to keep you cool from start to finish. The innovative Airline Mesh™ provides maximum airflow to help regulate temperature when it matters most.
Finished in a fresh yellow colourway, this cap offers a versatile look that adds a subtle pop to your kit, perfect for training blocks, race days, or your next trail escape.
If you’re tired of heavy, sweat-soaked headwear slowing you down, the M-Series is your answer. Lightweight, performance-focused and built for movement, this is a staple you’ll want on rotation.
