Regatta Okara Waterproof Jacket - 18 UK

The Isotex 15000 fabric provides a hydrostatic head of 15,000mm, meaning it can withstand up to 15,000mm of water pressure before leaking.

Please refer to the 'Size Guide' section in the product description. It provides chest measurements in inches for each UK size (e.g., 18 UK corresponds to a 43-inch chest).

The jacket is designed for waterproofing and windproofing. For very cold conditions, it is recommended to wear insulating layers underneath.

Re-proofing frequency depends on usage and environmental conditions. It's generally recommended when you notice water is no longer beading on the surface, typically after several washes or extensive wear.

The underarm zips are designed for ventilation and are typically water-resistant rather than fully waterproof. They should be zipped up during heavy rain to maintain maximum protection.

Waterproof means the fabric prevents water from penetrating. Water-repellent (like the DWR finish) means the fabric resists water absorption, causing it to bead up and roll off, which helps maintain the fabric's breathability and waterproofing.

Ensure all seams are properly taped. If leakage persists, the DWR finish may need re-application. Refer to care instructions for re-proofing.

Ensure underarm zips are open for ventilation. Check that the jacket is not being worn over non-breathable layers. The breathability rating is designed for active use; in low-activity situations, some moisture build-up may occur.

Gently clean the zipper teeth with a damp cloth and allow to dry. A small amount of silicone-based lubricant or wax can help ease movement. Avoid forcing the zipper.

The Durable Water Repellent (DWR) finish may have worn off. Follow the care instructions to clean the jacket and then re-apply a suitable DWR treatment.
