Hi,
I've been looking at a warmer belay jacket and the montane gangstang cought my eye.
I currently have a direct alpine impulse. https://www.directalpine.us/products/m-s-impulse-1-0-insulated-jacket-fw202...
I was wondering how much warmer the montane jacket would be? The impulse is around half the weight however it looks like around the core anyways, the fill weight is the same 133g/m2. Montane says primaloft gold whereas direct alpine says primaloft gold active. I'm not sure if there is a difference in these. The montane has a bit more insulation in the other areas of the jacket.
I'm confused where the weight difference between the two is coming from. Is the monatne a lot warmer?
Cheers
Glenn
