Why We Like The Rab Mythic Alpine Light Jacket

When our fast-moving, high-output alpine adventures go from cold to hot in a flash, we're glad we layered with the Rab Mythic Alpine Light Jacket. This insulated style redefines lightweight with a clever combination of 900-fill down and PrimaLoft Gold Active+ insulations, stitch-through constructed to cut down on weight and improve climbing, hiking, and touring mobility. Pertex Quantum ripstop offers weather protection at a barely-there weight. When we pick up the pace and no longer need the extra layer, the Mythic Alpine Light packs down tight to save room in our packs.


  • Technical midlayer for insulation without bulk or heavy weight
  • Ultralight 10D Pertex Quantum is durable, weather-repellent, and soft
  • Hybrid insulation with lofty, super-light, water-resistant 900-fill down
  • PrimaLoft Gold synthetic insulation at high-heat and high-moisture zones
  • Stitch-through baffles lower weight, optimize mobility, and secure insulation
  • Slim fit and articulated sleeves allow maximum range of motion
  • Fixed, part-elasticated hood and adjustable rear hem to seal out the cold
  • Stuff sack included for simple storage
  • Item #RABZ0KQ

Amazing jacket. Packable small, silly

Amazing jacket. Packable small, silly light yet warm. Adds several degrees to a sleeping bag to, esp with the hood. The different type of filling on shoulders and contact points are a brilliant idea.

Love this jacket

I've had this jacket for a couple of weeks now and it has become my go to jacket. Whether i go on errands, skiing, or snowshoeing it has been spot on. Just the right amount of warmth when you are active outside. I've been comfortable snowshoeing at 35°F with this jacket on. Absolutely love it. I'm 6'2 170 lbs and the large fits perfect
