Kevin B.wrote a review of SmartWool Microweight Boxer Brief - Men's on April 21, 2013
These are an awesome pair of boxers for hiking. I took one pair for ten days hiking at Philmont Scout Ranch in NM (to conserve on weight) and was comfortable each and every day. No chafing, no problems at all. I can't recommend these enough. They cleaned up great, which I can't say about a lot of other items I brought to Philmont...I wear them around now casually and they are oh-so-comfortable still.
