The flat and compact nature of this jacket makes it one of the most comfortable to wear. Designed for the RNLI 'Useless unless worn' campaign it is easy to wear with a 'proper' click front buckle, a comfy fleece neck and a bayonet fixed bottle viewable through the inspection window. The Ultra AX is also equipped with an emergency light and sprayhood as standard. They come as Auto models but the very clever design means that they can be easily converted to Manual using the supplied adaptor.
