These longies are crafted from a medium weight ribbed black cashmere.  We added a second layer of fine merino wool to boost the absorbancy. The waist band is crafted from hand dyed merino wool interlock. The second image is of the longies inside out. Rise is about 18and inseam is 9.5. These will arrive lanolized and ready to wear.  Please email us immediately after purchase if you prefer us to NOT lanolize.
