Other Bags to Check Out:
A surprisingly solid backpack for both daily carry and travel. Organization, professional looks and an expand/collapse feature for travel conversion.
The Outbreaker backpack from Tortuga is a solid 1-bag travel pick. I personally prefer the less bulky (and more spacious) experience of traveling with the Tortuga Setout, so be sure to check out that bag too. This Outbreaker, however, has quite a bit more padding and protection around the entire bag, so if you know you'll have delicate stuff inside you may prefer this one.
The ATD1 is an expandable backpack you can use for both travel and daily carry. Looks pretty damn good too. One of the best in this category for sure.
A medium-large sized travel bag with sturdy, rigid outer material, a couple external pockets and a removable internal divider that makes for actually a pretty interesting way of accessing things in transit.
A truly lightweight and sturdy bag that can carry literally everything you can throw at it AND make the load as comfortable as possible to carry.
