Feels like freedom. Claimed by our test pilots to be the most comfortable, flexible wetsuits they've ever worn, by a mile. Featherlight pre-stretched TB3-X neoprene, combined with our hydrophobic super stretch TB3 neoprene. This exclusive technology allows you to perfrom at the highest level with construction so light and comfortable, you'd swear you were surfing naked. TIP: These jackets fit on the tighter side when new. If you are torn between which size to buy, we suggest going the larger of the two sizes.
