Peak Design | Travel Backpack 45L

There isn't much this multi-award-winning bag doesn't do. The Travel Backpack from Peak Design is sleek and adaptable, based on the idea that you should only ever need one bag for any trip. Designed with a base capacity of 35 litres to fit with airline maximum carry-on dimensions, you can expand it up to 45 litres when you’re allowed a bigger bag – or compress it down to a more compact 30-litre daypack. Access the interior from top, back, sides and front via weatherproof, abrasion resistant zips – and if the internal capacity isn't enough for you, there are expandable side pockets, secret zip compartments and clever external straps for securing extra gear. A padded, adjustable backpack harness (including waist and sternum straps) stashes neatly under magnetic flaps in the back panel, so you can streamline it down to suitcase form for snag-free travel. Your shell fabric is weatherproof recycled 400D nylon canvas, engineered for long-lasting performance, and the whole thing is padded with ultralight foam. This is the slightly larger version for longer adventures (also ideal for pro photographers), but they also do a 30-litre model for weekend trips or daily use.
