SLAM'S Force 3 gear is made for when mother nature is throwing her worst at you. The heavier two-layer fabric has a lot more waterproofing than the coastal Force 2 gear and accomplishes this without sacrificing breathability for coastal or light offshore applications. The wide storm collar protects your face and microfleece lined pockets for added hand warmth. It is longer in the back with a heavy reinforcement backing for added durability. Safety features include large reflective SLAM patches on the shoulders and cuff, emergency whistle in right hand pocket, a large yellow reflective hood, and safety tabs on the zipper to attach a beacon or knife.
