Berghaus lists 0.640 kg (640 g), in the 600-799 g band. Its page gives no size, so this may not be the men's M weight; its shop data carries 660 g, a shipping weight we don't use. GO Outdoors, Blacks and Millets say approximately 640 g for UK size L.
In short
Good for
- Cold-weather walking and camp evenings, as a warm layer under or over a shell (Berghaus: down insulation with a Pertex Quantum outer)
- Standing around at camp: 600 fill duck down with a hood and hem cord adjustment
- Not a lightweight carry: 640 g is heavier than most belay jackets
Strengths
- 600 fill Hydrodown duck down: Berghaus says the water-repellent treatment keeps its loft in damp weather, but it publishes no test of this
- Pertex Quantum outer, which Berghaus describes as weather resistant and lightweight
- Hood, double hem cord adjustment and internal bound cuffs
- Five pockets, including a zipped sleeve pocket and an internal zipped pocket, and a reflective tab on the back
- Covered by Berghaus's Repairhaus repair service
Weaknesses
- 640 g with no size given, in the 600-799 g band, so a heavier carry
- Warmth, damp performance and durability aren't scored: no independent test of this jacket found yet
- No packed size, fill weight, fill power test method or fabric denier published by Berghaus
- Berghaus's fabric list also names 100% polyester additional insulation without saying where it sits, so it may be a mixed fill; we class it as down because Berghaus calls it a down jacket with 600 fill duck down and never describes it as a hybrid
