A midweight, half-zip baselayer that balances insulation and moisture management for aerobic activities in cold weather. BeCool Yarn Technology wicks sweat faster, body mapped venting manages body climate, and the seamless construction promises chafe-free comfort.


Polygiene® Odor Control Technology is a durable, effective and sustainable textile treatment that uses naturally occurring silver salt to stop the growth of odor-causing bacteria. The result? You can wear more and wash less!!

BeCool® Yarn technology : The BeCool polyamide fibre, uses an exclusive 4 channelled section which allows for up to 30% greater breathability compared to ordinary rounded sections. This innovative feature helps to increase the diffusion surface of the fabric by acting as a micro-propeller transporting humidity and heat towards the outer layers while at the same time favouring the airflow acting like a miniature fan.

The result? Unprecedented quick drying times and perfect climate control with immediate-release of moisture generated during physical activity. Products with the BeCool fabric are also seamless to further improve overall comfort.
