This jacket requires no special setup; simply put it on and adjust the hood and cuffs as needed. It's designed for compatibility as both an outer layer or a mid-layer. Its slim fit ensures it layers efficiently under a waterproof shell without feeling bulky, while the under-helmet hood integrates seamlessly with climbing helmets. For care, proper maintenance will ensure the longevity and performance of your jacket. It's generally recommended to wash technical synthetic insulation garments on a cool, gentle cycle using a technical cleaner designed for outdoor apparel. Avoid using fabric softeners, bleach, or harsh detergents, as these can degrade the DWR finish and insulation. Tumble dry on low heat with dryer balls or air dry away from direct heat to help restore loft. Re-applying a fluorocarbon-free DWR treatment periodically will help maintain its water repellency.
