David M.wrote a review of Ibex Woolies 150 Boxer Brief - Men's on July 30, 2013
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs small
I agree with a previous reviewer that these run a bit small, but nothing for me that resulted in profound discomfort. I deployed these on a recent climb of Mount Rainier, and they performed as hoped--no sagging, no chafing and the wool was soft and itch free. I can't comment on their long-term durability, but the initial impressions are favorable.
