In short
Good for
- Winter walking, climbing and shoulder-season belays (Rab)
- A warm down layer at 477 g, worn over a midlayer at camp or at rest
- Dry cold: the Pertex Quantum Pro outer copes with snow, spindrift and scuffs with rock (Rab), but this is not a rain jacket
Strengths
- 179 g of 800FP European goose down in size M, in micro and midi stitch-through baffles (Rab)
- Weather-resistant 20D Pertex Quantum Pro outer and Grangers fluorocarbon-free hydrophobic down finish
- Hood fits under a helmet; two-way front zip for belaying
- Hand pockets reachable in a harness, one doubling as the storage pocket
- More than 50% recycled materials (Rab); fluorocarbon-free DWR
Weaknesses
- 477 g in size M, in the 450-599 g band
- Warmth, damp performance and durability aren't scored: no independent test of the current jacket found yet
- Rab changed the jacket in 2025 (477 g now, 523.5 g before): some shop listings and older reviews describe the earlier version
