I am not your average size jiu jit su athlete (6'3", 290 lbs). It is not always the easiest finding gear that fits comfortably let alone that carryy size. That's has not been the case with Gold. I started with Gold buying spats. They fit so comfortably that moved to rash guards and shorts.Now I don't know if I'll got to another brand. I may not be sponsored but I don't know if you'll catch me at classes or competing or training in another brand. I'm here for the journey.
They are really great rash guards and high quality. They’re super tight if you wear a large size up. Gold customer service is 5 stars and top notch. They made exchanging mine for xl easy and exceeded my expectations
Great Quality and Look. Definitely "For the Journey." A must have for anyone in BJJ.
I love this company. I have the long sleeve and just added a short sleeve. The vents in the armpits are awesome. This thing is incredibly snug but not restrictive. Would highly recommend. I'd enjoy some more fun variations but I'm sure those will be coming in the future. 10/10 recommend gold bjj!
Very stylish and well made BUT pay very close attention to the sizing. I wear a large in most every brand so I ordered an XL. I will actually need an XXL in this. The shorts fit true to size and are also great. Nothing wrong with the rashguard. It just fits like a second skin.
