The Federate Adapt from Kathmandu converts between three separate modes: a 28L daily carry bag, a 38L carry-on travel bag, and a 50L check-in bag.
- Extreme conversion… from daily carry to carry on bag to 50L check in bag. This thing has tons of room.
- Very comfortable back panel… very breathable and cushy. Also nice to have hip-straps built in with the ability to hide them away.
- Very limited external access… this is my big gripe with this bag (but it does the other stuff so good that this bag is a real option for lots of folks).
Other Bags to Check Out:
The Topo Travel bag has a playful style, which I like a lot, but it is very serious about being a great travel bag. This is a classic.
The Stor backpack from Trakke is a lovely 30L pack for travel and gear moving.
The Prima System from Boundary Supply is, to me, the best in this category of kickstarter-y tech/camera/daily-carry because of the material feel and functionality in use.
An extremely versatile and feature rich bag that doesn't look half bad, the Errant has lots of organization in an innovative pack for everyday use. One of my favorites.
Miles the Duffel 40L from Millican is a sturdy little companion for travel (so long as you don't have to walk long distances with your bag!).
