Super Thermal 2.0 Unisex Undershirt

This jersey is crafted from a carefully selected combination of fibers that provide the best performance for winter cycling. Its design retains body heat while wicking sweat and moisture to outer layers, keeping you dry and comfortable at all times.

The fabric is thermoregulating, antibacterial, and gentle on the skin, ensuring an excellent weight-to-warmth ratio without causing irritation. All seams are flat and strategically placed to maximize comfort and prevent chafing.

The collar, with an optimized design, facilitates the evaporation of residual heat, making this garment ideal for cool and cold temperatures during the winter months. It’s the perfect base layer to pair with a long-sleeve jersey or jacket.

Additionally, the waistband features an asymmetric cut that enhances the fit, preventing the jersey from shifting or riding up during training. The anatomical panels are designed to prevent uncomfortable wrinkles, ensuring a flawless fit.

• The structure of the fabric is honeycomb, which facilitates the expulsion of sweat and moisture while maintaining stable body heat.
• Anatomical pattern that adapts perfectly to the body, preventing any air flow or circulation.
• The back is oversized to provide maximum thermal protection in the lumbar area.
• The neck is wide, to facilitate the evaporation of residual heat.
