Our Take

We recommend the Rab Mythic Ultra 0C because it completely redefines the modern warmth-to-weight ratio. By combining massive 900-fill down loft with innovative TILT heat-reflective technology, it provides our climbers with absolute, reliable warmth at a weight so staggeringly low you will hardly notice it in your summit pack.

Details & Features

Thermo Ionic Lining Technology (TILT) reflects heat back towards your body, significantly boosting the bag's warmth-to-weight ratio.
Ultra-premium 900-fill power European goose down offers unparalleled compressibility, lofting up instantly when you roll out your bivy.
Down is treated with a Grangers fluorocarbon-free hydrophobic finish to resist moisture and retain critical warmth in damp alpine conditions.
Incredibly light 7D ripstop nylon outer shell trims every unnecessary gram while remaining durable enough for rugged tent use.
Weight-saving trapezoidal boxwall baffle construction prevents down migration and completely eliminates cold spots.
Minimalist, 1/8-length zipper reduces bulk and saves weight while still allowing for easy entry and targeted ventilation.
Ergonomically designed internal collar and hood seal out drafts during frigid mountain nights.

Our Philosophy

We Simplify Outfitting

Whittaker Mountaineering was born out of the need for RMI to make sure their clients had the appropriate gear to get to the top of Mt. Rainier safely. After decades of trying, reviewing, arguing-over, and recommending gear, we can’t help but know what we’re doing by this point. We know what works, we know what doesn’t, and we use that expertise to stock our store.

Who are these guys?

Rab

Rab earned their reputation as "The Mountain People" by designing gear in the rugged peaks of Sheffield, UK, where foul weather is the norm. We stock them at Whittaker Mountaineering because their no-nonsense approach to alpinism aligns perfectly with the needs of our customers. They prioritize high-performance fabrics and honest construction over trends, delivering equipment that provides reliable protection when conditions on the mountain turn critical.
