Style Option: MudGear Fitted Race Jersey v3 Short Sleeve
(Badass Black)
MudGear obstacle race jerseys feature a tapered race cut that fits close to the skin without compression to avoids snags and stay out of the way of obstacles. The fabric is a custom poly blend with four way stretch that melds performance with toughness. This highly breathable material wicks sweat and has excellent drainage capability when fully submerged on race day. The weight also makes this jersey perform well for winter training as a base layer or as a second layer over a compression or fitted shirt.

It is go-to training shirt with a four way stretch that melds performance with toughness. Heavy duty flat lock stitching adds durability and strength. Long Sleeves function well as a single layer or base layer for colder training and racing.
