The Long Sleeve Thermal Baselayer with THERM-IX Technology is our best answer to the ideal thermal top.

The THERM-IX Technology is made of a polypropylene yarn that keeps the body warm and thermoregulated during those long and cold sessions out on the water.

The Tops name comes from a clever word play with the Roman Numeral “IX” that represents the iconic number 9 of our Founder, Luca Bellini

This revolutionary technology allows the user to maintain a warm body temperature while maintaining perfect mobility thanks to the seamless knit composition and body mapped compression that provides maximum elasticity and comfort on the skin.
