USGI Surplus Cold Weather Fleece Jacket - Used

The fleece is your friend.  Part of the ECWCS, the fleece is a midlayer for warmth and insulation.  Like a modern day M65, aka Smoking Jacket.  Fleece for most of the torso, with water repellant, and abrasion resistant nylone across the shoulders and backs of the arms, the fleece USGI jacket is an EDC kind of casual wear.  Athleisure before it was a thing, if you will.

Made of fleece, which is from the fleece tree from the country of Fleece.  Berry compliant fleece.

All jackets are issued and graded as a high condition 2, not quite condition 1.
