John Danaher is a jiu-jitsu mastermind and a guy behind notorious Danaher death squad. People often wondered why is he wearing rashguard all the time. In his Instagram profile he answered that question with 9 reason why:

” Arguably the question i am asked more than any other has nothing to do with jiu jitsu. “Why do you always wear a rashguard?” First let me dispel a commonly voiced, but incorrect theory. It has nothing to do with fighting or being ready for fights. In my current physical state, an aggressive five year old could easily defeat me with a simple kick to the knee or hip or even a push – a rash guard isn’t going to save me! My reasons are purely practical. First, they are very comfortable.”

2. “They are easily washed and dried”

3. “They are extremely low maintenance/wrinkle free/easily packed for travel etc.”

4. “being a low friction material, they are well adapted for wear under a jacket.”

5. “They enable me to comfortably demonstrate a technique in impromptu social situations to students.”

6.”they are warm in cold weather, yet cooling in hot summers due to wicking effects, and; if caught in rainstorm, they will dry in minutes even while being worn.”

7.” some clothing companies sponsor and support my athletes. I am proud to represent any company that supports my people. ”

8. “they are free as clothing companies are happy to see me wear their products.”

9.”There is considerable variation in rashguard design that can vary from informal daily wear to more formal wear for dates/occasions. When it comes to comfort and utility and low maintenance, I have never seen an attire that can beat track pants, sneakers, rash guard and fanny pack. If i find something more comfortable in the future i will switch to that. It may not be aesthetically pleasing, but I am already rather ugly and odd looking so I don’t even bother with clothing aesthetics as my looks are a lost cause – if I had to rely on looks and charm for anything in my life I would be a homeless beggar already ”
