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 Farpoint and Fairview 40L travel packs from Osprey are solid one bag travel bags with a little less thrills than other bags in similar sizes.
A very stylish and functional bag for both urban and outdoor use that does not let us down in organization, durability and thoughtful design.
The Viken from YNOT is as simple and sturdy a duffel as a modern urbanite could ask for. And it expands. Just lovely.
The Brain Bag from Tom Bihn is one of those lifelong companion bags — built to last for decades to come and designed with enough pockets and organization to be your constant helper, once you go brain it's hard to go back.
Easily one of my favorite bags for serious urban and outdoor daily carry. The Alpha 31 from Remote Equipment is a delight to use and will remain durable for years and years.
