Tom Murphywrote a review of SmartWool NTS Midweight 250 Color Block Boot Top Bottom - Men's on December 24, 2015
Familiarity: I've used it several times
Fit: True to size
Honestly, why it has taken me years before breaking down and purchasing boot cut thermals is beyond me. Every year I said I would get some and cursed all year that I didn't.
It's smartwool so the quality is top notch. Only ding I am giving it is I am a 35" waist and the Large do not feel tight enough in the waist. Everything else fits great, just that. I layer up enough that it is not a big deal, but it is noticeable putting them on.
