Lamb's Pride superwash sport weight 3 ply wool in a subdued olive marl. One ply is light blue-grey, one is light olive and one is dark grey. The overall effect is an rich olive marl ("ragg"); the guys I know like it a lot. This yarn is now discontinued. I have this and a few other colors.
 
Machine washable, but do use a very gently cycle. Personally I always handwash my handknits, and recommend that because machine washing involves a lot of rubbing against other fabrics, resulting in more fuzzing, and loss of stitch definition. Mothproofed, and made in the USA.
