The Karrimor Sierra Waterproof Jacket requires no complex setup; simply wear it over your chosen layers. It is compatible with various layering systems, performing best as an outer shell to protect insulating layers underneath. Its design is versatile for diverse outdoor activities, from casual walks to more strenuous hikes. For care, always refer to the garment's specific care label. Generally, waterproof jackets like this should be:- Washing: Machine wash cold on a gentle cycle with a technical wash specific for waterproof fabrics. Avoid regular detergents, bleach, and fabric softeners, as these can compromise the waterproof coating and breathability.- Drying: Air dry or tumble dry on a low heat setting. Overheating can damage the fabric's properties.- Re-proofing: Over time, the durable water repellent (DWR) finish may wear off. If you notice water soaking into the fabric rather than beading up, consider applying a DWR re-proofing spray or wash-in treatment to restore its performance.
