This is definitely an outerwear garment. Tahki Donegal Tweed is every bit as hot as you would imagine. I'm sure this sweater will be the most worn sweater I own, even if it can only come out in the dead of winter. If there weren't so much fiddly seaming involved, I would be tempted to make a second one in something like Cascade 220. I might just do that and omit the hood because really? I never take advantage of the hood and that's just a lot of extra knitting.
