Fitment Notes:

A racer cannot wear just any underwear during the long hours of intense driving and competition. Comfort is tantamount to success and Sparco's professionally designed Prime Plus (Prime+) racing underwear fits the bill perfectly.

Designed to provide a racer unparalleled comfort, the Sparco Prime+ Underwears are engineered to meet and comply with all standards under the FIA 8856-2018 rating. This underwear is made using highly breathable fabrics so that you are at ease even after prolonged wearing.

The F1-inspired double weave construction used to make the Prime Plus Underwear makes it one of the lightest yet durable fabrics you can get. The fabric has a constant weight of 220 grams per meter squared, one of the lightest in all racing gear.

The breathable inserts ensure optimum airflow so that you can stay cool and retain your focus during the race. It also helps in the regulation of body temperature at the optimum levels.

They come with greater protection against flame and heat. The close-fitting adds to the comfort while fearing. The ultra-flat design in Prime plus underwear reduces the pressure points as well.
