In addition to previous great examples, here are a couple more that have been useful on the Tumi 26141 (and similar Tumi bags with a sheath compartment). I use the little nylon wrist straps that come with cameras, phones and other gadgets to hang accessories on the bag straps and let them dangle into the sheath. Goodies are out-of-the-way and protected, but easily “fished” from the sheath without setting your bag down. Things like USB drives, LED keychain lights, and even a USB Bluetooth headset from Bose (comes in mini neoprene case) work great.

You can search Amazon for accessory camera straps if you need them. Photon makes a perfect light for the straps:

These are useful on long overnight flights and relatively inexpensive.
