Great base layer shirt.
I got this base layer shirt along with the ak select pant. They work great, the shirt has the Channel Tech which has better airflow and drys faster. Also it has some kind of stink proof tech. At least that's what Burton says, haven't found out about this yet. Also it has dry ride which takes the moisture away from your body which really does work. If you want a great base layer shirt, get this you wont be disappointed, it does have a pretty hefty price tag though.
