This windproof jacket was laboratory tested under a shower of 60 litres of water / m² / hour for 3 hours, which corresponds to fine, steady rain or a medium downpour. This test demonstrates that the water does not pass through either the sealed seams or the fabric. The adjustments and fabrics at the extremities (neck, waistband and cuffs) prevent water getting in while in a static position and greatly reduce it during physical exertion.

The neck is fastened by zip only, which can go up over the mouth to shelter the user from wind and spray.

For more waterproofing, less wind entry and greater freedom of movement: * the waistband features elasticated sections on both sides * the wrists have elasticated hems that can be turned back for a better fit according to the size of the wrist.

The positioning of the pockets is located according to 50N buoyancy vests, to remain accessible during the practice of the sport. The size of the pockets was designed so as not to be cumbersome or too heavy in order to not hinder manoeuvres or movement. Its design and tests were carried out with a snack of 2 cereal bars. The contents remain stable in the pocket and remain accessible. The anorak can be rolled up into its pouch for storage!
