The Isurus Ti Evade 4/3 Hooded Chest Zip Wetsuit was made to maximize warmth and comfort. Constructed out of premium Yamamoto neoprene, The Ti Evade 4/3 uses Yamamoto #39 in the lower body and Yamamoto #40 in the arms, neck, and shoulders due to the greater stretch characteristics. Yamamoto eco-limestone neoprene only absorbs 2% of water keeping the suit lighter out in the water. The Ti Evade is lined with Isurus’s Titanium line Z-Fleece liner designed to keep your core as warm as possible. The Isurus Ti Evade 4/3 has seams reinforced with Internal taping to increase seal and durability. Spot taping keeps the arms as flexible as possible.
