The 1" Cafe/Ristretto Messenger Stabilizer is designed to keep your Cafe Bag, Imago or Ristretto close and prevent it from swinging around to the front when you're riding your motorcycle or bicycle, or just moving fast on foot. Designed to work with the Small Cafe Bag, Medium Cafe Bag, Large Cafe Bag, Imago, and Ristretto for iPad, Ristretto for 11" MacBook Air, and Ristretto for 13" MacBook Air or Pro. Uses one-half of your bag's waist strap (the half with the male buckle); if your Cafe Bag, Imago, or Ristretto doesn't have a waist strap, you can order one here. Zoom!
Andrew Hsu, a longtime customer, came up with the concept. Read all about it.
