Rab Mythic Ultra Jacket – Graphene Down, Windproof Hooded Coat for Alpine & Mountaineering (XL)

Overview

The Rab Mythic Ultra Jacket is built for serious cold and high‑performance environments. Reframing Rab’s warmest down insulator with a Graphene‑labeled edition, it pairs lofty warmth with practical features designed for alpine ascents, climbers on steep routes, and mountaineering missions. The jacket blends comfort with durability, inviting you to test its capabilities across shifting conditions without overpromising outcomes.

Core warmth and moisture resilience

At the heart of the Mythic Ultra is a 900‑fill down insulation that balances exceptional loft with compressibility. A hydrophobic finish, applied with Nikwax, helps maintain loft and warmth when dampness threatens to sap insulation performance. The result is a soft, responsive feel that remains thermally reassuring through chilly belays and wind‑swept ridges.

Protective, responsible shell

The Pertex Quantum shell is windproof, water‑resistant, and breathable, while being 100% recycled. This combination protects against gusts and light moisture, supports comfortable interior humidity, and aligns with sustainable design values—all without sacrificing mobility during climbs or scrambles.

Mountain‑ready design details

• Helmet‑compatible hood with internal adjustment and a stiff brim to seal out wind on exposed situations.
• Hem adjustment and elastic cuffs to seal drafts and tailor the fit over midlayers.
• Offset box wall baffles and stitch‑through sleeves and hood for consistent warmth and durability.
• YKK zippers at hand pockets, chest pocket, and center front for reliable operation in cold weather.

Real‑world use and versatility

In practice, the Mythic Ultra excels from approach to camp: it invites confident movement on steep slopes, belayed moments on windy ledges, and cool evenings around a stove. The jacket’s substantial warmth remains readable when you layer, while its packability helps you stash it away when you’re moving fast on ascent routes.

Care and longevity

Designed for multi‑season use, the jacket benefits from straightforward care—follow label guidance to preserve loft and hydrophobic properties. Regular reapplication of the protective finish can help maintain performance over time, ensuring the garment continues to serve on your next expedition.
