I travel frequently for both business and pleasure, and the Morphus 22 is my go-to bag. I purchased it in 2013 and have seen 2 generations of the same product. I've waited to write my review until now.
The Morphus 22 is an excellent bag -- but -- it may not be the best bag for everyone. Understand it's limitations and it will serve you *very* well. But don't get mad at the bag if it's "too small". (eg: No, it's not the bag's fault. You probably packed too much. Get a bigger bag.)
The Morphus 22 is large enough for extended travel IF you know how to pack. The main compartment is unstructured space and performs best when used in conjunction with Pack-It system (or similar) products.
Here are comments on specific features of the bag:
Bi-Tech: The bi-tech fabric is highly resistant to abrasion. I've not had any issues at all. Bi-tech is puncture *resistant* -- it's tough -- but it is not puncture *proof*. Put another way, don't go out of your way to abuse your bag even if the bag is capable of taking most normal abuse square on the chin.
Back-Pack Form: FIRST RULE OF LIGHTWEIGHT TRAVEL: "Never travel with more than you can't run with."
The Morphus 22 is not an *ideal* back pack, but it does it's job when it needs to without issue. The male section is, essentially, the same as the EC Gear Hauler -- an unstructured sack without significant compression features. The straps are strong and surprisingly comfortable. The front panel is padded so you don't feel anything dig into your back. If you keep the hard-shell section attached, you can hoof it through an airport...just don't expect to be stylish in doing so.
Wheels: I've dragged this bag through sand and they still spin smoothly. Tell me what is a better test? The wheels works great.
If you overload the bag with dense, heavy loads, you can start to make the wheels splay outward (since there are two separate wheel housings). Again, this isn't the bag's fault -- the only time splaying happened was when I had both bags (~90+L / 100lbs) in the fully expanded form with all the weight on the wheels houses.
Another reviewer mentioned it was hard to maneuver with only two wheels. I've not had this issue. It is a wide-ish carry-on and plane aisles are narrow. Steer it straight and you'll be fine. The design prohibits 4 spinner wheels, and if you need that feature, Eagle Creek offers *plenty* of options. But the two wheel design is generally (for all luggage) more durable and results in greater luggage capacity (since you do not give up bag height for wheel housing).
Polycarbonate "Bathtub": This is the real reason I love the Morphus 22. The plastic shell is just stiff enough to protect anything fragile. I've packed bottles of wine, nested in clothing, and . Soft sided bags just don't have the same structure and flexibility.
Laptop Pocket: This is one of the few detractors. When packed full, it is difficult to get into this pocket. You MUST be careful to not overpack the interior space, otherwise it will press outward on laptop pocket making it very tight.
Overpacking: This is a **large** carry-on. IF OVERPACKED, THE FRONT OF THE BAG WILL DEFORM AND WILL NOT FIT IN ALL PLANES. YOU'LL BE ASKED (TOLD) TO GATE CHECK THE BAG. This is not the bags fault, but something you must realize with soft-side luggage. Never trust the specs for bag depths on soft-sided bags. You can deform the bag by ~1-2" by stuffing it too full. This means you might be allowed on the plane with it, but it will be impossible to fit in the bin without unpacking during the boarding process. Do yourself a favor -- accept this "limitation of the product" and don't overpack.
But if you do overpack, don't be surprised if you must gate check.
SUMMARY: I'd get this bag again in a minute. What you are *really* paying for is: A) The No-Matter-What Warranty, B) Flexibility to have 200% your normal capacity *if* you need it. The rest are details.
You can get less expensive well-made carry-ons, but if you have needs like mine (with drastically changing packing needs, often without returning to your point of origin), then the Morphus is worthy of consideration.
