Comments about Eagle Creek Hybrid Hauler Medium:

The medium Hybrid Hauler is the perfect carry-on for me. I've wanted this bag for a long time. Its good looking, rugged, easy to carry, maximizes cargo space, and is highly stowable.

Small wheeled carry-on bags always leave me worried about finding overhead storage space when I get on a plane. I prefer to travel with a carry-on that may be stowed under a seat in a pinch. I've been using a carry-on with a single shoulder strap, but as a 50 year old, that's getting less comfortable. This bag distributes the weight on well padded shoulder straps and is a dream to carry. Crowded places are easier to navigate with a backpack. The bag is flexible, stows easily, and no cargo space is wasted for wheels and telescoping handle so a lot fits into this bag.

I don't want to repeat Eagle Creek's description, but what I'd like to highlight is that there are 2 main compartments, but EC designed the bag so you may use either compartment and get the full volume. You don't have to pack stuff in both compartments to fill the bag. However, you have the flexibility to separate wet/dry or dirty/clean, etc. Both main compartments have lockable zippers.

The backpack straps are on the front/top of the bag so the clean part of the bag goes against your back. Also, if the bag is ever checked, having straps that cleanly tuck away keeps them from getting snagged on a conveyor belt.

There is a lockable document pocket which is on the front/top of the bag so the pocket is safely tucked against your back while carrying as a backpack. This is a nice security feature.

The bottom wet pocket (toiletries?) does not lock.

I have had this bag too short a time to judge its durability, but I've been using Eagle Creek products as long as I can remember and they've all been great. I tend to get interested in new innovations long before the old products wear out :)
