For all day comfort the Smooth Full Brief is cut from a fabric which is a blend of Tencel Modal and elastane. Tencel Modal is a sustainable fibre that derives from renewable wood sources - it is super soft, breathable and comfortable to wear. The fabric and elastic trim are very stretchy, which allows this garment to be dual-sized. Special flat sewing technique with extra soft thread is used on seams to attach the elastic, to minimise show-through under clothing. Cotton lined gusset.
