These longies are made from felted, ultra soft cashmere.  While these are a good weight for cashmere, these are a lighter medium weight and would be best for daytime use or double up with another cover for heavy use.  The waist band is made from undyed organic merino wool interlock.  Rise is about 16 and the inseam is about 8.  These will arrive lanolized and ready to wear but please email us right away after purchase if you do NOT want us to lanolize.
