I love the fit and best of all I love the thermal lining ,inside the vest which equates to longer time in the water , its even better with a rash shirt over it for double the warmth . It's not bulky , I love the smoothly feel and flexibility of the wetsuit . Great vest definitely a must have for summer sessions in the water . The zipped pocket located on the back of the vest is great for your keys .will probably get the long sleeve version down the track when the water temperature gets a wee bit colder! Do your self a favour and grab one ,
