This bag is, without a doubt, the most useful piece of luggage I have ever owned. I travel for business and use this bag only for any trip less than 5 days. When I travel with my wife and 2 kids, my wife packs more than anyone would ever need or use (right fellas?) Before I had this bag, it was impossible to manuever all our belongings through the airport without the help of a cart or vallet (there goes a $5 tip!) Now I can throw this bag on my back and free my hands up to handle the other bags and crazy kids. LOVE IT!!

I love this bag! It's the perfect carry-on wheelie. Of course, you do have to detach the daypack otherwise it won't fit the overhead compartment. The big red wheels and sturdy handles makes running through the airport a breeze. My bag never twisted once even through escalators, switchback lines and bumpy asphalt. This was a problem with every other carry-on I've ever had until now. I packed it for a weekend trip and still had space to spare. Perfect when you buy lots of souvenirs like me during the trip. A great feature that I didn't notice until I was packing was the attached zippered front cover that was tucked away. When the daypack is detached, it reveals two netted pockets on the front and a horizontal zipper on the bottom that holds the second front cover. It's dual zip and gives you an extra storage pocket that great for books or games to keep you occupied when you're traveling! The daypack was just the right size that I didn't have to worry about knocking things over in cramped stores. The four compression straps with clips were very useful. I even used it as a jacket holder!

I've tried out the backpack mode but haven't field tested it yet. It has cushy shoulder straps and waist belt. It felt very secure albeit heavy in this mode.

It's the best carry-on I've ever used! I can't wait to use it again with my Doubletrack 25 in Australia!

This pack is unbelievably good. Great design, very rugged construction and good materials. I just traveled across three continents and this bag was perfect - great in airports in "wheelie" mode, excellent when making your way through the city and public transport in "pack" mode, and the day pack is pretty perfect for out-n-about stuff.

The smallest size is legit for airline carry-on, although with the daypack attached it raised a few questions. Just detach and put it on your back as your "personal item" and all should be fine.

Nice work North Face.

Very well made and rugged pack. Many useful pockets for small items like pen, cell phone, ipod
etc. I was able to pack enough stuff for a week
long trip cross country. Highly Recommended.
