We keep our stuff secure on crowded commutes and daily adventures with the Osprey Packs Transporter Roll Top 25L Backpack. This durable daypack is designed to help us comfortably lug the essentials for a day of work or play and features a secure roll-top closure that works with the water-resistant fabric to keep out moisture when our commute is a bit rainy. Speaking of the fabric it's more than durable enough to withstand the constant bumps and bruises of crowded subway cars and buses while a padded internal laptop sleeve keeps your computer or tablet safely stashed as you bike hard on city streets or get knocked around on bumpy train rides.
