Rab Xenon Insulated Jacket

Outland USA says:
The Xenon Jacket is made with lightweight Atmos outer, and filled with 60g/m Stratus recycled insulation. With no need for quilting, this versatile and lightweight technical jacket eliminates cold spots, making it perfect for keeping you warm and protected from the elements on alpine belays. An under helmet hood with stretch binding and elasticated cuffs help eliminate drafts, while zipped handwarmer pockets and a two-way opening front zip with insulated internal zip baffle provide extra warmth when belaying. Updated with a slimmer fit, the Xenon Jacket packs down into an internal zipped pocket which doubles as an integrated stuff sack. Lightweight, warm and water-resistant, the Xenon Jacket is a versatile jacket that you can take on every adventure.
