I have both the FLX Pro and Pro BJJ Pants. Both are amazing, Flx pro obviously as the name suggests, are more flexible has an ever so slight stretch and a bit more give. They are lighter too!
The Pro Pants are just as good and think will hold up longer down the line. Can't go wrong with either

I don’t know about these pants. The concept is great and they are definitely tough. I wear a size 34 jeans so that’s what I ordered and it feels like old school 80s jeans that are high waist. They’re extremely tight. I have tried going up a size to 36 and they’re just too big around the waist. It doesn’t cinch up properly. I would like for origin to have odd sizes 31, 33, 35, and so on and so on. I just ordered origins regular gi pants cause there supposed to be roomier in the legs. We’ll see how that turns out.
SizingRated -2.0 on a scale of minus 2 to 2Runs Small True to Size Runs LargeWas this helpful?OUOrigin USA2 weeks agoHi Anthony,
Thank you for taking the time to share your detailed feedback about the FLX PRO BJJ PANTS and for your honest assessment of the fit challenges you've experienced with the sizing. We sincerely apologize that the 34 feels too tight with that high-waist, restrictive fit, while the 36 is too loose around the waist without proper adjustment capability.
Your specific feedback about needing odd sizing options like 31, 33, and 35 to bridge the gap between standard even sizes is valuable information that we'll share directly with our product development team to consider for future iterations, as we understand how critical proper fit is for performance gear that needs to move with you on the mats.
We appreciate your continued interest in our gi pants line and hope the regular gi pants provide the roomier leg fit and overall comfort you're looking for. Your insights about the fit differences help us understand where we can improve our sizing options to better serve athletes with varying body types.

These pants are the best BJJ pants ever. No more pyjama bottoms with strings to tie, they fit nicely and stay up, the velcro crotch helps them stay in place and the fabric feels tough but not too restrictive. Highly recommend! I had to go up a size from normal but have tree trunk legs so could be a me thing!
SizingRated -1.0 on a scale of minus 2 to 2Runs Small True to Size Runs LargeWas this helpful?OUOrigin USA4 weeks agoWe're thrilled that the fit system is working exactly as designed. That combination of proper waistband construction and the velcro crotch reinforcement was specifically engineered to keep everything locked in place during rolls without relying on those traditional drawstring systems that can fail when you need them most. The fabric balance you're experiencing between durability and mobility is exactly what we built into this design, ensuring these pants can handle serious training while giving you the freedom of movement that's essential for BJJ.
Your feedback about the sizing really helps other grapplers understand the fit characteristics, and we appreciate you sharing that insight. That's the kind of real-world assessment that helps the BJJ community make the right gear choices.
Thank you for choosing Origin for your gear!
