Peak Design 45L Travel Backpack

When it comes to one-bag travel, few packs are as versatile, durable, and thoughtfully designed as the Peak Design 45L Travel Backpack. Debuting with a bang at the 2018 Outdoor Retailer show, this backpack swept up three best-in-show awards, quickly establishing itself as a must-have for travellers who demand both functionality and style. And now, with an upgraded weatherproof X-Pac® construction, the Peak Design Travel Backpack is even more prepared to take on any adventure you throw its way.

Designed to meet international carry-on size requirements, the Peak Design 45L Travel Backpack ($320) is the perfect companion for those who prefer to keep all their gear in a single bag. But don’t be fooled by its compact dimensions—it’s got tricks up its sleeve. The bag expands to a full 45 litres, transforming into a gear-hauling powerhouse that can handle everything from a weekend getaway to a longer expedition. And when you don’t need the full capacity, it collapses down to a more manageable 35 litres, making it ideal for day trips or lighter travel days.

What really sets this bag apart is its smart organization. With multiple access points, including rear, side, front, and top, you can get to your gear quickly and easily, no matter how you’ve packed it. The exterior is crafted from weatherproof, laminated X-Pac® fabric, providing ultimate protection from the elements while maintaining a sleek, modern aesthetic. The UltraZip™ zippers, made with abrasion-resistant UHMPE thread, are built to withstand years of heavy use, ensuring your backpack stays functional and secure no matter where your travels take you.

Comfort is key when you’re carrying everything on your back, and Peak Design has thought of everything. The ergonomic shoulder harness and hip belt are fully stowable, allowing you to streamline the pack when it’s not on your shoulders. Meanwhile, 360-degree handles give you a variety of carrying options, whether you’re slinging it over your shoulder, grabbing it by the side handle, or carrying it briefcase-style.

Additional features like stowable external straps, side pockets, interior pockets, hidden pockets, and quick-access pockets ensure that everything has its place. A padded laptop sleeve keeps your electronics safe, while the rugged exterior ensures that your gear is protected from impact. And, as with all Peak Design products, this backpack is Fair Trade Certified and 100% carbon neutral, so you can feel good about your purchase.

Whether you’re a seasoned traveller or just getting started on your journey, the Peak Design 45L Travel Backpack is the ultimate tool for mastering the art of one-bag travel. With its unmatched versatility, durability, and smart design, it’s a backpack that’s ready to go wherever you are—and then some.
