In short
Good for
- A light extra layer for cool evenings, cold starts and breaks on the hill
- Layering up on winter hikes, or taking the edge off a chilly day at the crag
- Fastpacking and long trips where every gram counts
Strengths
- 295 g in size M, in the lightest weight band
- TXdown sheet insulation sits flat against the body and layers easily
- 30D Pertex Quantum shell, windproof and made with recycled fishing-net yarn
- Stuffs into a hand pocket with a loop to clip to a pack or sling
Weaknesses
- No hood, and Rab gives no fill power or fill weight, only the sheet weight (50 g/m²)
- A light insulation layer: Rab sells warmer down jackets with more fill
- No packed size published by Rab
- Warmth, damp performance and durability aren't scored: no independent test found
- Down-based insulation loses warmth if soaked
