I've been traveling extensively - internationally and domestically - for years. I had been an ardent, loyal eBags Pro Slim Laptop Backpack user since 2017. No more. After taking my Skyborne Smart-Pack out on its maiden, cross-country (U.S.) voyage, I'm ready to say: The Smart-Pack is just flat-out the superior backpack. Here's why: 1. Cavernous-Roomy. I'm not one of those "pack for a 2-day trip" people (i.e. packing a pair of shoes, dress shirts, toiletry kits in backpack instead of a suitcase .. a la the Skyborne design-promo photos). I'm more of a 'Bose headphones case, a Moleskin notebook, a large paperback book, and electronics and diabetic supplies' person. And damn if the Sky-Pack holds more than any other carry-on backpack I've used before -- without appearing or being-feeling bulky. There are snazzy, zip and mesh compartments in each Smart-Pack section, and the inclusion of wireless charging in one of the straps is just awesome. 2. Design and Aesthetics. The Smart Pack is "Smart" in both design and features, sure, but also in regards to style-looks. I've gotten more compliments on the Smart-Pack in one trip than I ever did with the eBags ProSlim (or its predecessors) over the course of 5 years and over a million miles traveled! To top it all off, Skyborne's Customer Service team is amazing. I'm a believer. You will be too.
