Gi pants with flex crotch

I know that Sprawl and R2C make them, does anyone else?

 

Hyperfly makes them, not sure if they sell separates tho.

Also Cageside sells their own version at a great price

I picked up a pair when they were discounted down to like $15 for BF. They're alright. Quite a bit cheaper than the alternative. I don't find that the stretch crotch makes that big a difference, it's still my glutes.
