Get a discount on any new Gap denim purchase, including these Straight Fit Jeans for men, 54.50 (in classic dark blue wash).

If you're like me, you have a tall, messy pile of denim in your closet, and the bottom 6 or 7 pair of jeans never see the light of day.

From now until Sunday, you can stop by Gap, GapKids or babyGap and drop off your old denim, and the jeans will be converted into UltraTouch Natural Cotton Fiber Insulation and donated to communities in need.

In return, you'll receive a 30 percent discount on new any denim in the store.

For this project, Gap has teamed up with COTTON. FROM BLUE TO GREEN, an organization started in 2006 that converts denim to the UltraTouch Cotton Fiber Insulation and donates it to help with building efforts for communities in need.
