The Regatta Birchdale II Waterproof Jacket is designed for immediate use. To 'set up' for optimal performance, adjust the grown-on technical hood using its adjusters for a snug fit that doesn't impede visibility. Secure the adjustable cuffs around your wrists and tighten the shock cord hem to prevent wind and rain from entering from below. The hi-tech water-repellent centre front zip should be fully engaged. This jacket is compatible with layering systems, allowing you to wear appropriate base and mid-layers underneath for varying temperatures. For care, while specific instructions are not provided, typically, waterproof and breathable garments like this should be washed with a technical wash designed for performance outerwear, avoiding fabric softeners and harsh detergents. Always refer to the garment's internal care label. Air drying is usually recommended to preserve the integrity of the waterproofing.
