This bag is a perfect example of what a carry-on rolling bag should be. At 22 inches tall, the Briggs & Riley Baseline will fit comfortably in the over-head bin or under your seat. This bag also comes with CX expansion; compression system increases packing capacity, then compresses back to original size for easy overhead storage (up to 25%). My favorite feature is the 4 wheels on the bottom of the carry on that allow me to roll or spin 360 degrees! Another great thing that I love about this rolling bag is that Briggs & Riley offers a Lifetime Performance Warranty! And that even covers airline damage! The warranty really works! My buddy had his Briggs & Riley rolling bag for over 15 years and they fixed it for him twice. Amazing customer service. My honest opinion is if you are an avid flyer, this carry-on bag is worth the price tag ($519) and will save you many headaches down the road. To purchase via Amazon, click here!
