Rab Mythic G Jacket 1000FP TILT – Maximum Warmth-to-Weight Efficiency

Description

The Rab Mythic G Jacket is an ultralight down jacket designed for mountain activities where weight and thermal efficiency are critical. It uses 1000 fill power European down—one of the highest levels available in actual commercial products—combined with advanced construction to maximize warmth with minimal weight.

It is a highly logical garment for mountaineering, fast-paced expeditions, and technical mountain activities, where every gram counts and the warmth-to-weight ratio makes the difference compared to more conventional down jackets.

Real technical performance

The combination of 1000FP down with TILT (Thermo Ionic Lining Technology) allows for body heat to be reflected inward, reducing thermal loss without the need to add more insulation.

Compared to a traditional down jacket (700–800FP), it offers clearly superior thermal efficiency at a much lower weight. Its 7D Atmos™ fabric and ultralight construction improve compressibility, making it an extremely efficient garment in a backpack.

The insulation mapping allows heat to be concentrated in key zones, optimizing performance in the cold and dry conditions typical of technical mountain activities.

Comparison within the range

Mythic G Jacket: maximum warmth-to-weight efficiency within Rab and one of the most advanced on the market.

Neutrino / Electron: more robust and durable, but with higher weight and lower efficiency.

Microlight: more versatile for general use, but clearly less technical.

Within the current market, very few garments reach this level of fill power in actual commercial products.

Recommended use

• Technical mountaineering
• Fast-paced expeditions
• Ski mountaineering
• Technical trekking in cold conditions

Is it for you?
