US Army veteran Robert Patterson began building his Sheath Underwear concept in 2008 while serving in Iraq. His problem was that men's underwear wasn't effective at preventing irritation and chaffing, especially in the intense desert heat. Sheath addresses this issue by incorporating a fabric pocket in the crotch area to isolate and contain the scrotum and penis from rubbing against the inner thigh. About two years ago, Patterson launched a Kickstarter campaign to make his underwear concept a reality. Toolbox welcomes Sheath Underwear as an emerging, exclusive brand to our assortment.
