Michael Clarkewears Step One.

The fabric is organically grown bamboo viscose: smooth, cool against the skin and lighter than cotton, with a natural drape that cotton never quite gets.

There is no breaking-in period. The pair you put on this morning feels the same as the pair you have washed fifty times.

Ultraglyde™ panels on the inner thigh are friction-resistant, so skin no longer rubs on skin and the leg stops riding up when you walk, sit or run.

The waistband holds without digging in. Pull them on, forget about them, no adjusting at the lights.

The 3D Comfort Pouch is shaped, not flat. It keeps everything separated and supported, with room where you need it and none where you don’t.

Three fits, one pouch: boxer brief, trunk, or boxer brief with a fly.

Bamboo viscose is moisture wicking: it pulls sweat off your skin and lets it evaporate, so you stay dry through a humid summer day, a long flight or a hard session.

Less moisture means less odour and less chafe. The three problems cotton gives you on a hot day, gone.

360° arch support holds the sock to your foot, a reinforced heel and toe take the wear, and a stay-put silicone grip means no slipping down inside the shoe.

Sweat-wicking too, so feet stay dry. Crew, ankle or no-show: whichever you wear, they stay where you put them.
