Tigerotor77Wwrote a review of Eagle Creek Tarmac AWD 22 Carry-On Bag - 2325cu in on December 25, 2014
Familiarity: I've used it several times
Short version: the Tarmac AWD 22 is an excellent carry-on bag. It offers decent interior space, the comfort of knowing it'll comply with just about every airline's carry-on policies (for dimensions), and a solid construction. The weight, clamshell design, and lack of interior pockets may make it less appealing for certain travelers.
Detailed review: I was looking for a rolling bag that was well-built and lightweight (under 9 pounds). A laptop compartment or suit storage bag were not necessary.
Weight: the bag tips the scales right around the advertised 8 lb 4 oz. It's heavier than others in its class, but the counterpoint is its construction. Solid handles (very little flex), tough cloth, and durable wheels give the bag a dependable demeanor. Note: some airlines -- eg Lufthansa -- impose a carry-on weight limit of ~16 pounds.
Build: I've had it gate-checked due to flying on regional jets six times, and so far no abrasions or scratches. The wheels are still great. Handle still telescopes and locks in position with no issues. No frayed threads.
Size: it's a 22" bag, but that includes the wheels. As such, you'll get less interior volume with this bag than with 22" rollaboards. However, it'll fit in most any overhead bin.
Features: the coat keeper is a great idea. The side buckles aren't all that helpful. Some reviews mention that they are at seat armrest height, but this hasn't been my experience on larger (737/A320 sized planes and up). There is a lack of pockets -- definitely not a lot of places to stash random small items, so pack smart!
Design: the clamshell design is both good and bad. It makes it easy for organization of items, but it also prohibits carrying thicker objects easily. The rails for the telescoping handle are inside the unit, which prevent having a flat packing area. The wheels are 58 mm in diameter and are hard plastic, which makes them noisy over textured surfaces.
Overall: I'd give the bag 4.5 stars but without 0.5 stars, 4 it is.
