900FP. Nothing heavier.
At the extreme end of the lightweight spectrum, the Rab Mythic Alpine Light Jacket is for alpinists who treat every gram as a decision. The 10D recycled Pertex Quantum shell at 28gsm is as light as down jacket fabrics come, wrapping 900FP European goose down treated with a Nikwax fluorocarbon-free hydrophobic finish for loft and warmth that holds even in damp alpine conditions. Stitch-through construction keeps weight and bulk to an absolute minimum, and a zoned hood filled with both down and PrimaLoft Gold on the sides and base adds targeted insulation where heat loss is greatest. Pre-curved, articulated sleeves move with the body on technical terrain, and the jacket packs into its own stuff sack for transitions. With a slim fit and a center back length of 28.7 in at size M, this is a precision tool for fast-and-light alpine objectives. Add it to your rack and move faster.
