Medium to Loose Fit Has a harness hook slot, but the fit is more of an "on the beach" fit than an "in the water" fit.
Ion Shelter Jacket Amp - Neo Water Jacket
The Neo Shelter Jacket Amp is your essential companion for cold and windy days on or off the water. The neoprene thickness of 2mm will keep you warm and toasty. A stretchy and non-water absorbant jersey-plush lining shelters against cold temperatures. Serving as an additional wind-stopping outer layer and for extra warmth, this jacket can be worn whilst using a harness thanks to the harness hole opening. Designed with a relaxed fit, you’ll be loving this for action-packed sessions!
