jm1607 - Were the boxer briefs you bought from Sierra Trading Post Redram?
I started off with Core4 100% merino. They developed holes fairly quickly. I believe Core4 has switched to a merino/polyester blend since and they are more durable. I then went to Redram from STP. Great price and quality. Ice Breaker made them under the Redram brand name. I still use them. Last year I started wearing two pairs of FirstLite red deserts. Slightly better quality than Redram, but significantly more expensive. The longer legs are nice - they stay down.
