Championship Fight Shorts
Lightweight MMA Fight Shorts
The ONX Championship Fight Shorts are MMA fight shorts built for speed. The fabric weighs 160 GSM, or grams per square meter, the standard measure of how heavy a fabric is. A lower number means a lighter, faster-drying, more breathable short, which is exactly what keeps these moving when the pace picks up. The 160 GSM nylon and spandex fabric strips out the bulk of heavier shorts while holding up to the abrasion of daily grappling. 4-way stretch and a side split hem give the legs full range for kicks, sprawls, and level changes, so nothing about the short slows the athlete down.
These are outer fight shorts, not a compression layer. Where ONX compression shorts sit close to the skin for muscle support, these are cut to move as a lightweight competition short over a base layer or on their own. Sublimation-ready construction makes them a fit for teams and gyms building custom fightwear.

Construction
Built to Move, Built to Last
NYLON AND SPANDEX FABRIC
Nylon carries the abrasion resistance, fast drying, and tensile strength. Spandex adds the 4-way stretch and shape retention. Together they hold a lightweight 160 GSM build that moves without bulk.
REINFORCED FLATLOCK STITCHING
Flatlock seams sit flat against the skin to reduce chafing during grappling. Reinforced high-stress areas take the friction of daily training without seam failure.
STRETCH CROTCH GUSSET
A stretch gusset opens up the range for deep stances, high kicks, and sprawls. No pinch at the point where most shorts restrict.
SIDE SPLIT PERFORMANCE HEM
An open side split frees the legs for full extension. Kicks and level changes without the fabric dragging on the knee.
DRAWCORD WAISTBAND
A flexible elastic waistband with drawcord closure locks in a secure fit that stays put through rounds without digging in.
