I'm thinking about getting a decent synthetic insulation jacket for 5000-6000m peaks. I read quite a bit about the DAS Parka here, seems to be most ppl's favourite. I came across the Igniter Jacket from FirstAscent while researching on the internet, has anyone made some experiences with this one? I can't really find any reviews other than those from people that are somewhat affiliated with First Ascent.
Any other SYNTHETIC insulation jackets that can keep up with the DAS?
