1. Sixs Functional underpants PN5
The Carbon Underwear leggings with padding provide full protection for the legs and ensure comfort while sitting.

2. Sixs Functional suit STXL
The SuperLight Carbon Underwear® base layer is designed for the warm season when heat and humidity can be challenging. In these conditions, a garment is needed that maintains the athlete's optimal body temperature and transports sweat (and heat) outward without absorption. The result is a pleasant feeling of dryness and freshness on the skin, provided by our SuperLight Carbon Underwear® material (36% lighter than Carbon Underwear®). Additionally, outerwear such as leather suits can be put on more easily.
