Joshua Barneswrote a review of Icebreaker BodyFit 150-Ultralite Anatomica Brief - Men's on December 5, 2013
Familiarity: I've put it through the wringer
Fit: True to size
This was my first pair of merino underwear so I can't give a great comparison to other Icebreaker underwear or those from other brands. What I can say is that I love these things.
When these come up in my underwear rotation, my brain does a fist pump. These things are crazy comfortable. I won't buy cotton underwear anymore. Definitely worth the extra $$.
