Our men's knitted silk skivvies are naturally stretchy, so there's no bagginess, and seams don't show under tight clothing. Super thin and lightweight, they are breathable and feel barely there. Also, we've added extra silk fabric in the gusset liner to keep him feeling secure. More delicate than our silk charmeuse trunks, we recommend hand-washing these or placing them in a garment bag on the gentle cycle, cold water setting. Designed in Toronto.
