The Chelsea Shell jacket from Helly Hansen features Cudora Fabric on the shoulder, elbows, sleeves and hips - common wear-points for work coats.
The arm pit areas have a long zipper, which allows you to adjust the level of circulation needed.
The Chelsea Shell jacket has an adjustable hood and drop hem in the back for added protection from the elements.
Hook and loop tabs at the wrists are adjustable and can be cinched down to keep water out of the sleeve.
