""You’ve never worn a more comfortable boxer!" Using wool, not cotton or synthetics? Look, I like wool. I wear wool, including underwear. It has real advantages. But there are limits. Then I got these, and wore them. If they aren't the most comfortabe boxers I own, they're really close. Remarkable. I haven't tested them in heat yet. That's a few months away, but I expect that they'll perform very well. I'm going to have to add to my collection of these, not just for hiking but for everyday wear. I'd put these right beside the 440g Blizzard half-zip, Prescott 230g turtleneck, and my 440g vest as WoolX offerings that have no real competition among the many other wool brands I've tried."
