Whether you’re heading out for business or vacation, the right backpack makes packing smarter and traveling easier.
1. Osprey Fairview 40 (Women-Specific)
Built with women’s bodies in mind, this backpack features a shorter torso length and curved shoulder straps that actually fit comfortably. The 40-liter capacity gives you plenty of room for clothes, shoes, and toiletries without feeling bulky. What makes it suitcase-worthy is the full clamshell opening that unzips completely flat, so you can pack like you would a traditional roller bag.
When you reach the airport, the harness and hip belt tuck away behind a zippered panel for a cleaner look. At 22 x 14 x 9 inches, it meets most U.S. airline carry-on requirements. Pack smart with compression cubes, and you can easily travel for a week with this single bag on your back.

Bright colors and rugged durability define this adventurous pack. Made from recycled fabrics, the Allpa combines eco-consciousness with serious travel functionality. Its clamshell design opens wide like a hardshell suitcase, revealing organized compartments that keep your gear sorted and accessible.
Measuring 22 x 12 x 10 inches, the depth might push limits on budget airlines with stricter rules, but it works beautifully for most carriers.

Access points are thoughtfully placed—side zippers, front panel, and top opening all make grabbing items easy without unpacking everything. For flights, compress it down to the smaller size to meet stricter airline requirements. The magnetic closures and smooth zippers feel premium, and the weather-resistant materials protect your belongings in any climate.
4. Aer Travel Pack 3 (35L)
Minimalist design meets maximum functionality in this urban traveler’s dream. The boxy shape uses every inch of space efficiently, so you get more packing room than softer, rounded packs. Tough ballistic nylon can handle rough baggage handlers and years of frequent travel without showing wear.

Internal compression straps keep everything stable during travel, preventing that annoying shifting that throws off your balance.
