This year round jersey was designed in New York City by the legendary Alex Ostroy.

The main body of the jersey is made with LIGHT POINT, a lightweight microfiber with micro-perforations that enhance breathability and airflow, ensuring rapid drying and UPF 50+ sun protection.

The sleeves, crafted from SKIN 120, also offer UPF 50+ protection and are laser-cut for a sleek, second-skin fit, ideal for high-performance comfort, even under intense effort.

"Muur" is flemish for "wall" which describes the short but steep and tough climbs at Belgian races to which this apparel item pays homage.
