Hey guys, i have merino base layers and a thermawrap montbell jacket. The thermawrap jacket is great for hiking while your on the move in cold environments (25F-45F) give or take a few degrees) in my opinion, and not suitable when camped in colder than those temperatures without adding another baselayer or some other item of clothing.
What i need is an outer layer, synthetic (down getting wet is too significant for me to use it in the area I live) only, and as light as possible. Something like a thermawrap except warmer, that would replace my thermawrap on very cold trips.* OR * A synthetic insulating item I could layer with the thermawrap, such as another synthetic jacket or a vest. Being dry is handled by waterproof outer shell.
OPTION 1: synthetic VEST + Thermawrap
What about vests? Would putting a thermawrap jacket OVER top of a vest (synthetic) or otherwise, keep me warm at very cold temps? Would the vest become saturated with moisture that becomes trapped in a double insulation setup (possibly thermawrap vest + thermawrap jacket 6 + 8 oz = 14oz)?
Option 2: +1 Merino baselayer + Thermawrap jacket
This would be two layers of merino wool or one really thick layer of merino wool + Thermawrap jacket.
Option 3: Warmer synthetic Jacket
Leave the thermawrap jacket at home, pack a heavier one.Or Combine thermawrap vest + thermawrap jacket 6 + 8 oz = 14oz)? Thanks
