I have worn this rash guard 2-3x per week for the last year and a half. It has held up great. I wash it immediately when I get home from training and it has never developed a bad smell even after all this time. It has become worn, especially in the areas where the Gi is most actively rubbing on it, but that is to be expected. Great Quality product. I will be ordering another one. This has a side panel under the arms, so is not as tight as other rash guards, making it more comfortable. I would recommend ordering a larger size than you wear in a tee shirt if you don't like a tight fit. I wear a men's medium tee shirt, but an XL in the rash guard because I don't like the rash guard tight around my arm pits.

These are the best rashguards I've found by far. Visiting the Gracie Academy in 2014, I bought 3. One is always under by gi, or exposed for nogi, and machine washed and dried after every use, and are still almost like new.

They are also classy in style, and give a professional look that is often lacking in Jiu-Jitsu wear.
