hi all; I'm upgrading an old ski-parka as an over-layer and it needs an attached hood, what's the best weight of insulation for a hood? Remembering that I will be getting the stuff from Spotlight as all I need is a few grams, looking at manufacturers site they range from 100GSM to 250GSM for belay parkas, and it looks as if Thinsulate or Polarguard are the only insulations being used at the moment, I was going to get the cheapest stuff being sold but thought I would check first.
Body insulation in this old thing is the original woven blanket "Thinsulate" and I am surprised at how warm it still is after 30 years
