Style Option: MudGear Fitted Race Jersey Short Sleeves
(Badass Black only)
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.

Heavy duty flat lock stitching adds durability and strength. Long sleeve versions include the specially designed reinforcement along the forearm and elbow that reduces the suck of a long slow crawl under barbed wire or a prolonged elbow plank on pavement.

The MudGear Race Jersey is intentionally fitted and tapered. Use the size chart below as a guide, but when close or in doubt, go a size larger. Remember that a fitted race cut shirt will accentuate every muscle and hug every fat roll. Plan accordingly. This is a performance race shirt, not a look-good-on-the-treadmill shirt.


Style Option: MudGear Loose Tee Short Sleeves
(Badass Black only)

The F3 MudGear Loose Tee features the same functionally strong, advanced wicking fabric found in our fitted race jersey in a comfortable loose cut. 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.
