Any suggestions on which is the better purchase.
Thermawrap is .2 ounces and 15 dollars less and it has a full zipper. It seems like a no brainer to me, but I thought I'd seek insight from BPL. This is going to be my primary insulation layer on trips combined with a merino base and either a fleece or down vest for cold spells.
I realize down is lighter than both, but I decided to go with synthetic because of the extra layer of protection from rain.
I guess I'm asking about build quality and warmth really. The zipper issue is a non-contested +1 for the montbell. Anyone have experience with both to compare? I know the Thermawrap has gotten rave reviews from the BPL crowd but have not seen them compared directly.
