Men's waterproof jackets

Men's waterproof jackets exist to solve one problem properly: keeping rain out at the seams and shoulders, the two places a lesser jacket almost always fails first.

Construction and technical detail

Built with a taped-seam construction, every seam is sealed against water penetration rather than relying on the outer fabric alone, which is where cheaper waterproof jackets typically let water through after repeated wear. A breathable membrane sits beneath the outer shell on the more technical styles, allowing moisture out without letting rain in — a detail that matters considerably on a long walk rather than a short dash between doors.

Choosing men's waterproof jackets for different conditions

A hydrostatic head rating above 10,000mm indicates genuine protection against sustained heavy rain, rather than the light showerproofing found on more casual outerwear. A storm flap over the main zip and an adjustable hood add further protection in genuinely poor weather, details Hackett London has built into its technical outerwear since expanding beyond tailoring in its early collections.

What makes a jacket genuinely waterproof rather than water-resistant?

A genuinely waterproof jacket has taped seams and a hydrostatic head rating typically above 10,000mm, while a water-resistant jacket relies only on a treated outer fabric that eventually lets moisture through under sustained rain.

How should a waterproof jacket be washed?

A technical wash formulated for waterproof fabrics, followed by a low tumble dry or gentle iron, helps reactivate the durable water repellent coating, which regular detergent can strip over time.

Can a waterproof jacket be worn over tailoring?

A clean-lined waterproof jacket without excessive technical detailing works well over a blazer or knitwear for smart-casual settings, particularly in navy or black.
