Piranha Gear Black Uniform Pants - Drawstring Waist The music is over and we have left the building. Piranha Gear no longer sells on Amazon and has closed down as of May 1, 2018. If you're reading this listing and considering buying the item described, YOU ARE BUYING A COUNTERFEIT ITEM! Sadly Amazon literally encouraged fake sellers and brought us to our knees. So please do NOT spend your money on the above item. What you get will not be from us, and it only makes us sad to think this sort of thing is still happening. Perfect choice for those just starting or looking for some good "back-up" pants. Designed for grappling arts such as Judo and BJJ, but you could use them for Aikido, Jiu-Jitsu, MMA or any general grappling styles. Even stand-up arts like Hapkido that have lots of grappling. Very durable single weave fabric - 100% heavy weight cotton with reinforced seams, double layered and cross stitching (quilted) in knees. These pants have a "traditional" drawstring waist - though we do carry the "elastic and drawstring" version as a separate item.
