Brilliant running cap
Love the quality of the Fractel M-Series running caps. This is my second and both are brilliant. Exactly what I need in terms of having a high quality, lightweight and breathable cap, which I know is keeping me protected from the sun. Also, despite having a larger head, these fit brilliantly.
