In 1947 when Sunspel introduced the boxer short to Britain, they also perfected its design. With just a few minor tweaks, they still produce boxer shorts to their original specifications. The seams are double-turned and feldlocked to avoid rough edges. The rear has a distinctive back panel instead of an uncomfortable central seam. And each pair is cut from 100% long staple fine cotton for unmatched lightness, softness and breathability.
