Our Sport Boxer Brief is built for the days that ask more of you. It's knit from a 210gsm merino jersey made in Australia from fine 18.4 micron wool, with 5% elastane blended in for stretch and rebound. The fabric snaps back into shape instead of loosening up as the day goes on, so it stays put without bunching and gives noticeably more support than our original boxer brief.

The heavier knit adds a little warmth for cold mornings and shoulder seasons, but merino's breathability keeps it comfortable year round. It's soft against the skin, wicks moisture when you're working hard, and naturally resists odor.

Gray is a classic heathered gray that disappears under anything. A smooth wrapped waistband sits flat without digging or rolling, and a contoured front panel adds structure where you need it.

Returns: Only unopened, unworn boxer briefs can be returned. Items that have been opened cannot be returned.
