This wet suit is top of the line when it comes to fit, comfort, and functionality. I prefer the chest zip, but having the back zip is nice for easy in and out/ quick sessions. The flush feature in the legs is killer for draining excess water while not sacrificing any warmth while in the water. This is by far the nicest suit I've ever owned due to the quality of materials and extra tech features Mystic has put into into their suits. Good job Mystic you all really nailed this one, and thank you REAL for carrying nothing but the best equipment in the industry.
