The Definition 7mm steamer replaces the former 6.5mm version of this popular cold-water wetsuit while providing even more stretch, warmth, comfort and features. Special tailoring and strategically placed panels in the chest area, sides, arms and legs, and behind the knees, create a suit that fits like a glove and provides extra stretch where it’s needed most. Bigger abrasion-resistant shoulder, knee and elbow pads provide maximum abrasion resistance.
