BS1602 is specially made for professional racing cyclists. Its tailoring fits people's body shapes better, which is based on aerodynamic principles to help reduce wind resistance and increase riding speed.
The padding of BS1602 uses a high-density cushion (density of 100kg/m3 support force), which can ensure the ride constantly for few hours, over 100 kilometers each time. Besides, the chamois will not be piled up or moved away, causing unnecessary friction. All in all, it will efficiently reduce over 90% of the pain during ridng.
The design of BS1602 believes less is more. There are no other extra decorations on them, so they can be matched with any jersey.
