Very comfortable (for a neck protector).
Can get a little hot.
The Smart Parts label can't be easily removed.
One of the best paintball items I've purchased!
It's very comfortable to wear, and you really feel like it's going to protect your neck (unlike the many other neck protectors that feel like flimsy pieces of cloth). It does get a little hot after running around all day, but all neck protectors have this problem. I still feel it's well worth the slight discomfort.
The first time I played, I took it off, because I was getting too hot... should've taken off the extra t-shirt instead, because sure enough, in the very next game, I got hit in the neck (at about 6 feet) by an idiot "friend" (AFTER the ref ruled me out and I was in the process of standing up to walk off the field).
Anyway, since then, I've been hit in the neck twice while wearing this, and both times, all I felt was a slight thud. No pain, and most importantly, no welts.
I highly recommend this over the JT offering, which is nearly worthless.
The only reason to not wear this, is if you feel more manly by having a hicky-like welt on your neck.
