I wear one every time I'm on the mat whether it be for drilling, sparring or even just warming up.
I have one of these:

It's really comfortable and it fits better than any other boil & bite I've ever had (even if it sorta is a glorified, denser boil & bite).
I read that the guy who invented bodyarmor said that the most important factor is comfort, because if its not comfortable then you're not gonna wear it so it doesn't matter how strong it is. This thing is so comfortable, you can leave it in while you talk or get water. I almost forget that I'm wearing it sometimes.
