This item is a modification to the original long john and is cut shorter to only cover 3/4 of the legs. This means that when worn under trousers they remain discreet and as they're not as long as long johns, there's no need to tuck the ends into your socks - so ideal for regular suit wearers. Easy care home machine wash at 50C. Maintains warmth even after many washes.
