The Porto Neoprene Jacket is perfect for your swim or paddle. With its 2mm thickness it is great for added insulation during the colder months when you want to step it up from your swimsuit without going for a full wetsuit.  It's stretchy and features flatlock seams and a zip in the front for fast and easy entry. Feedback from customers indicates that this jacket is small fitting. If in doubt you might want to size up.
