Super Thermal 2.0 Unisex Undershirt

This base layer 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.

At Twenty One Cycling we know that nobody likes to fall, but in cycling these things happen. That's why at Twenty One Cycling we offer an Accident Replacement service to all those cyclists who during their rides have damaged the product due to a fall.
This service consists of a 50% refund of the value of the damaged product for the purchase of another product of the same family. The products that are not purchased in the official stores of the brand or on its website will not benefit from this service, nor those that are purchased more than 12 months ago.
To proceed with this you will have to send the damaged garment to the offices of Twenty One Cycling along with a valid proof of purchase. Once received we will check that everything is correct. If this is the case, you will be sent a discount code for the replacement of the garment.
This code can only be used by the person who purchased the damaged product, as it will be linked to their email and account. This code does not apply to promotional products.

If we can give the best, we will give the best. Inspired by the innovative and avant-garde spirit of the city of Barcelona, our brand seeks to leave its mark on each of the products we produce, fleeing from the established standards and creating unique garments with materials of proximity and maximum quality. Like those architects stubborn in their work, we like to be present in every smallest detail to obtain a result as durable as excellent.
