Sido - New Generation Underwear

The unique material, Hohtai, used for Sido underwear took many years to develop and was born through the meticulous manufacturing culture Japan is known for.

Compression wear may increase short-term athletic performance but the pressure also leads to fatigue. Sido underwear was developed to overcome this problem. It is so comfortable one forgets it’s being worn.

Medical bandage material has led to a revolution in underwear

Hohtai Pants are not just underwear made from this bandage. The technicians at Sido experimented with, and changed blend ratios of, the materials and weave tensions over and over again to create a new material never seen before. They created a material that retains the softness of bandage but with superior elasticity and seven times more breathable than regular material (a blend of 95% cotton 5% polyurethane) (Kaken Test Center - Japan Chemical Fiber Inspection Association). This led to the development of Hohtai Pants.
