Access Made Easy Stow away your laptop (up to 15") safely and grab it easily with handy buckles and easy zips. Brave the Elements Weatherproof construction keeps contents dry, and zip-away rainfly covers everything in heavy downpours. Expandable From a slimmer 26 liter profile, the Parker Commuter Backpack expands to 35 liters for when you need more storage. Simply unzip from end to end, it quickly expands and when you zip it up it quickly compresses back to 26 liters. Sourced responsibly Sustainability is more of a journey than a destination. And we hope the steps we take are always in the right direction. While we continue to grow our collections of bags made from recycled pre- and post-consumer materials, there are other ways we can leave a smaller footprint — like 100% recycled and recyclable shipping bags, manufacturing more bags closer to home to reduce emissions, and partnering with suppliers who help us create products that require less water, use fewer chemicals, and promote fair and ethical labor.
