ION's Neo Zip Top 2/1 LS Skin men is a staple piece for everyone who wants to add extra style points to the lineup. The long sleeve jacket acts as a perfect addition when riding in boardies for light protection against wind. Hot_Stuff 2.0 thermo lining increases heat retention while Silk_Stuff offers a pleasant next-to-skin feeling. Neo Tops have a more detailed and technical construction than that of standard rashguards, providing 100% UV protection, efficient heat retention and a reduction in irritation and bruising often caused by the harness or surfboard.
