The Travel Backpack 20L takes the DNA of Peak Design's original 45L Travel Pack—clean lines, clever access, lifetime durability—and distills it into a smaller, sharper format that works by itself or as the perfect companion to your roller. Compact enough to be your go-to personal item, expandable enough for spontaneous weekends, and sharp enough for even the most business casual of occasions. The clean exterior hides thoughtful design everywhere: a padded 16” laptop sleeve, expandable main compartment, hidden water bottle and AirTag™ pocket, and magnetic strap keepers that keep things tidy under the airplane seat. Built from weatherproof Versa Shell™ and finished with Peak Design’s signature UltraZips, it’s the kind of bag that always looks composed—even when you’re running late. Travel light, travel smart, and look good doing both.Works seamlessly with Peak Design Packing Cubes and Pouches, sold separately. Organize clothes, shoes, toiletries, tech, and more. Fits Peak Design Camera Cubes—up to Smedium when compressed, or Medium when expanded. For heavier photo gear carry, we recommend the original Travel Backpack 45L. For slightly more capacity, try the Travel Backpack 30L. Make It A Camera Bag Throw a Peak Design Camera Cube into your Travel Backpack and instantly turn it into the most versatile and capable travel camera bag on the planet. Both sizes fit up to a Large Camera Cube and provide convenient rear access. The 45L also provides dual side access, so you can grab your camera without taking the bag off.
