1. Cherokee scrub pants. Wore them 3-4 times per week for 14 hours at a time for 3 years. Was sitting on the toilet at work and realized they were so threadbare I could see the floor through my pants.
2. New Balance sneakers. Only got a year out of these, developed holes where my pinkie and big toes were. Still wore them for several months that way--not buying super lightweight shoes again. My new ones are a different brand too.
3. Eddie Bauer backpack. This one doesn't even count, because my brother is still using it daily for class. It was my husband's middle school backpack--was used for his high school, four years of college, and four years of office work. It then passed to me, I used it all of nursing school. One of the straps was only hanging on by a few threads when I graduated two years ago. My brother came to visit and his suitcase broke, so I gave it to him thinking it would only last him the trip home, and he's still using it without fixing the strap! Those threads are miraculous.
