This basic item will keep you comfortable at all times. The PRTBARU undershirt is made of wicking mesh, helping to regulate your body temperature. Another big advantage of the PRTBARU is the sustainable fabric of the upper part, made out of 100% recycled PET – the rest is 92% polyester-8% elastane. This cycling jersey has a regular fit, sitting comfortably close to the body, and comes in a solid black colour.
