boblo – completely agree about direction and company ethos
ir_bandito – sorry but another thing to consider is that they’re not strictly all the same, even vests that use primaloft insulation. There are different versions of Primaloft and even within one type such as Primaloft One you can get different weights of it, e.g. 40g, 60g, 100g etc.
A general rule is that the heavier fill material is warmer as it is more insulation but it will take longer to dry if you wear it in a proper downpour. It’s a balance of total weight, pack-size and warmth.
e.g.
Montane Prism vest use 40g Primaloft one with Pertex Microlight outer
Rab Generator uses 100g Primaloft one with Pertex Quantum outer – (so more warmth but the outer fabric isn’t as tough as Prism)
Arcteryx Atom LT Vest uses own brand 60g CoreLoft fill
If you are unsure go for Haglofs, Rab, ArcTeryx or Patagonia as they are brands that you rarely have problems with.
It’s really worth reading online reviews and blogs before buying
