The Timbuk2 Aviator Travel Backpack has an internal capacity of less than 30 liters and we think it's a great option for individuals who plan to check one bag, but still want to carry-on a few critical items that won't quite fit into the personal item. Although you could use this as a personal item, it is a tight fit under the seat in front of you. The Aviator has a super padded built-in laptop sleeve, tuck away backpack straps, and more than enough space for books or magazines, as well as that emergency change of clothes in case your checked bag gets lost in the shuffle.
About TIMBUK2 Founded by SF bike messenger Rob Honeycutt, TIMBUK2 created the iconic messenger bag in 1989. Since then, we've been making bags built to last a lifetime right here in the Mission District.
