I've got a 320 weight full-zip sweat shirt without a hood (Quantum GT, I believe). I'm looking for something a bit heavier with a hood. I noticed this has 260 inside fleece plus an outer shell. Am I correct to assume the total warmth from this garment (260 + outer shell) will be warmer than my single layer 320?
Also, is this jacket machine washable? I know machine drying is never recommended, but I would like to avoid dry clean only garments.
