Regatta Birchdale II Waterproof Jacket - Navy Blue

Isotex 15000 refers to the jacket's fabric technology, indicating a waterproof rating of 15,000mm hydrostatic head and a breathability rating of 15,000g/m²/24hrs. This means it offers excellent protection from heavy rain while allowing significant moisture vapor to escape.

The Birchdale II is a waterproof shell, offering excellent protection from rain and wind. For very cold weather, it is designed to be worn over appropriate insulating layers, such as a fleece or puffer jacket, to provide warmth.

Yes, but it's crucial to use a technical wash specifically designed for waterproof, breathable outerwear. Avoid standard detergents, fabric softeners, and bleach, as these can damage the waterproof membrane and DWR finish.

Regular washing with a technical cleaner and occasional tumble drying on a low heat can help reactivate the Durable Water-Repellent (DWR) finish. If water stops beading on the surface, consider applying a spray-on or wash-in DWR re-treatment.

The chest pocket and lower pockets feature hi-tech water-repellent zips and are designed to offer ample storage while resisting water ingress. While highly water-resistant, for sensitive electronics in extreme downpours, it's always safest to use an additional dry bag.

Articulated sleeves are pre-shaped to match the natural curve of your arms. This design provides an enhanced range of movement, reducing fabric bulk and preventing the jacket from riding up when you lift your arms during activities like climbing or cycling.

The Durable Water-Repellent (DWR) finish may be worn or dirty. Wash the jacket using a technical cleaner for waterproof fabrics and then tumble dry on low to reactivate the DWR. If needed, apply a new DWR treatment.

This could indicate reduced breathability, often caused by dirt or improper washing. Ensure the jacket is clean (wash with technical cleaner) and that you are not overdressed underneath. Your base and mid-layers should also be breathable.

Clean the zipper teeth gently with a brush and warm water. If still stiff, apply a small amount of zipper lubricant or wax designed for outdoor gear to the teeth.

Check for any debris or damage within the adjustment mechanisms. Clean thoroughly. If they are still not functioning, contact customer support or a repair specialist.
