In short
Good for
- Light extra layer for breezy summits, belays and cool camp evenings
- Mid layer under a waterproof shell
- Budget synthetic layer for damp UK hills
Strengths
- 344 g in size M, in the top weight band
- Soft, silky lining that Live for the Outdoors called comfortable enough to forget you are wearing
- Packs into its own chest pocket, which has a hang loop for a harness; 3-year Alpine Bond guarantee
Weaknesses
- No hood
- Thin 60 g/m² fill: Alpkit sells the 0Hiro as its warmest synthetic jacket
- Live for the Outdoors found the fit somewhat boxy
- No packed size published; only one independent review of the current men's jacket, so warmth, damp performance and durability are estimates, not reviewed scores
