Rab Mythic Ultra Down Jacket Review
The RAB Mythic Ultra Down Jacket is renowned for being warm and ultralight. The 900 fill power down in this jacket is some of the finest; it provides the maximum amount of insulation while at the same time keeping the weight very low. Moreover, the design features an additional heat-reflective TILT, or Thermo Ionic Lining Technology, layer, which increases the warmth without extra bulk.
Performance
It performs very well in extremely cold conditions, making it suitable for winter mountaineering, alpine climbing, and other activities done at high altitudes. It is highly regarded, particularly regarding its ability to keep a wearer warm in sub-zero temperatures while remaining very light and packable. At size L, the weight of the jacket is roughly 506 grams, an impressively low weight considering the warmth the jacket provides.
Design and Features
Material: The outer shell is Pertex Quantum 10D nylon ripstop, strong yet very light. And the down inside is treated with Nikwax PFC-free hydrophobic finish to make it drier in wet conditions.
Hood: Helmet-compatible and adjustable, the hood offers fantastic coverage and a warm head. However, a number of users claimed this can feel a bit floppy when without a helmet.
Pockets: It has fleece-lined hand warmer pockets at the front which are perfect for warming up the hands on cold days and internal dump pockets for storing gloves or other things.
Fit: Alpine Fit. The fit of the jacket is quite tight but sufficient to accommodate the insulation layerings inside it. An additional feature is a drawcord hem and elasticated cuff which helps keep the cold away from your body.

- Exceptionally warm for its weight
