Kids FOX racing jersey and pant set. Jersey is a kids small. Pants are K4. These fit my son from age 3-almost 5. Worn while riding his dirt bike or stacyc. Easy single button closer allowed him to stop and take himself to the restroom. These are the 180 leed pants. Some snagging on the jersey from the Velcro on his chest protector. Pants show wear as well, but still a lot of life in them.
