A happy ending to my dilemma. I went by the local bike shop during lunch and they had all their winter gear on sale for 20% off, plus they had one Craft balaclava left. So I bought it. Then on my drive back to the office I cut through a neighborhood on my bike commute route, and there was my old balaclava laying on the sidewalk. I rode right by it this morning and didn't see it, but the light was dim. So now I have two balaclavas.
