The Long John MOBY is made of 4mm double-sided neoprene, ideal for canyoning or water sports. Flat seams, Supratex reinforcements on the knees and buttocks, YKK double zip on the torso and cut-out ankles for quick donning. The Long John also has a unisex cut, which makes it suitable for all body types. The Long John is more comfortable to use for these sports because the constant movement of the arms can create irritation in the arms when wearing a full body suit.
