Omni-Heat Thermal Reflective Omni-Tech Waterproof/Breathable Fully Seam Sealed Zip-in and 3 Point Interchange System Attached, Adjustable Storm Hood Synthetic Insulated Liner Built with the kind of clean style and technical versatility that'll take on snow-bound mountains and rain-drenched cities alike, this highly adaptable interchange jacket combines a lightweight, waterproof and super-breathable 2.5-layer shell and a toasty zip-in liner with both synthetic insulation and thermal-reflective warmth. The result is a toasty, wet-stopping jacket with a shell and liner that perform and look great on their own.
