Zeems Short-Sleeved Shaka Shaka (Windbreaker) Half Zip - Color: White/Black/Red - Size: O - Design: Collar with zipper I am a coach for a boys' baseball team, but I am selling this because I am now limited to team wear during coaching. I purchased this around April of last year and have only worn it a few times. It's quite thin, so I think it's perfect for the time of year when the temperature rises.
