Fight Form

Common Questions

FREQUENTLY ASKED QUESTIONS

Fight Form makes the only natural fiber fight and training shorts built for combat sports. The shell is organic cotton and Tencel, the liner is merino wool, the waistband is natural rubber. No polyester, no synthetic elastic, no added PFAS. If you want non-toxic activewear that holds up to BJJ, MMA, and striking, these are the questions worth asking first.

The Answers

WHAT FIGHTERS ASK BEFORE SWITCHING

What makes Fight Form different from other fight short brands?
Fight Form is the only fight short built from natural fiber. Every major fight brand runs 100% synthetic polyester, because it is cheap to source and fast to produce at volume. We build the shell from organic cotton and Tencel, line it with merino wool, and finish it with a natural rubber waistband. You get the performance the synthetics were chosen for, without the plastic sitting against your skin.See the collection
Are Fight Form shorts actually free of PFAS and microplastics?
Yes. The shell is 60% organic cotton and 40% Tencel lyocell, the liner is merino wool, and the waistband is natural rubber. There is no polyester, no synthetic elastic, and no added PFAS chemistry anywhere in the short. This matters because synthetic fabric sheds plastic microfiber through wear and washing, a single synthetic wash load can release close to 500,000 fibers, and those particles have since been measured in human blood and in 100% of the testis samples tested in a 2024 study. PFAS, the finishes used for water and stain resistance in much synthetic gear, are a separate problem we sidestep by not using them.1234Read the materials
Can organic cotton hold up for BJJ and MMA training?
Yes, with the right construction. On its own cotton would not survive hard grappling, so the shell blends 40% Tencel lyocell into the organic cotton for tensile strength and moisture movement, and the gusset is reinforced and built in to take the load of guard work, hip escapes, and high kicks. The honest tradeoff against polyester is a slightly slower dry time after a hard session. What you get for it is no microplastic shedding, no PFAS finish, and no synthetic chemistry against you through a 90-minute roll.
Do synthetic workout clothes really affect testosterone?
The clearest evidence points at phthalates, the plasticizers used in many synthetic textiles. In large population studies they track with lower testosterone in men at everyday exposure levels, not just industrial ones. The research does not isolate clothing as a single source, so treat it as one input among many. The precautionary case is still stronger for combat athletes than for casual gym-goers: you train hot, you sweat heavily, and the fabric stays in high-friction contact with your skin for long sessions. Heat and sweat are exactly what move these compounds out of fabric and toward skin. We use no synthetic fiber, so there is nothing to migrate.5Read the materials
Why is merino wool used in the liner?
The liner sits against your skin every round, so it is the last place you want synthetic chemistry. Merino regulates temperature in both directions and resists odor on its own, with no antimicrobial treatment added. In controlled wear trials, polyester built up markedly more odor than wool over the same use. Merino also stays soft through repeated washing instead of going stiff and holding smell.6
How is Fight Form different from natural fiber gym brands?
Some brands build natural fiber for general gym use. Fight Form is built for combat sports specifically: BJJ, MMA, boxing, Muay Thai, and kickboxing. That shows up in the construction. The Fight Short carries no pockets, so nothing catches a finger or a training partner on the mat. The gusset is reinforced for guard work and hip escapes. The natural rubber waistband holds through scrambles instead of rolling down. It is tested in live training, not just on a spec sheet.See the collection
What is the difference between the Fight Short and the Training Short?
Same materials, different cut. The Fight Short is a close 6-inch competition length with no pockets, built for grappling and striking. The Training Short is a 7-inch relaxed length with side pockets, and the right pocket zips and fits a phone for the gym and daily training. Pick the Fight Short for the mat and the Training Short for everything around it.Fight ShortTraining Short

Health findings on PFAS, phthalates, and microplastics come from drinking-water, blood, and population studies. Clothing is one avoidable source feeding the same total exposure. We state strong findings plainly and frame dose-dependent ones to their evidence level.
