Peak Design are the kind of brand that treats the humble bag as an engineering problem worth obsessing over – and the results speak for themselves. Their Travel collection is built around a simple idea: that one well-considered bag should handle any trip, whatever form that takes. Backpacks that compress down to 30 litres for a day out or expand to 45 for a long-haul flight. Duffles that reconfigure from grab handle to shoulder strap to full backpack harness in seconds. A Dufflepack that borrows the best of both worlds. Every zip is weatherproof, every fabric is recycled and Bluesign-approved, and every design is Fair Trade certified and carbon-neutral in manufacture. Carryology's Brand of the Year and National Geographic's best travel pack don't come from cutting corners – they come from a San Francisco team that genuinely can't stop improving things.
