gets HOT on warmer days
Ok. Short and simple, this thing does what it's supposed to. I bought one yesterday because my neck has always been a prime target in a game. Anywho, it was like 70 degrees out, blaring hot sun, no wind and I'm ready to play. I strap it on, head into the woods, OH CRAP. It suddenly starts to burn like crazy. I haven't tried it in cold weather yet, but I'm sure it keeps you warm there. The thing is itchy too, but you can't blame it, almost all neck guards are. Also, like other neck guards, it can be adjusted into almost any size neck which is good.
You won't be sorry. You will be if your playing on hot days, so just save it for the cold. It's less than 10$ I think and should be good for anyone. Check it out.
