If you need to bring everything with you, and we mean just about everything, then the Pelican U100 Urban Elite Laptop Backpack might be the way to go. This top-end pack includes a solid poly case that can be submerged for up to 30 minutes.
Obviously this one is ideal for the trail, but could work for urban commuters who want a bit of extra production or travelers who want to carry a lot of stuff. It will fit up to a 17-inch laptop, and offer an additional 16 liters of capacity for other gear. The airtight case even includes a pressure-release valve so it can be opened on a plane.
We’ve seen a lot of rugged gear designed for hikers and those who have adventures off the grid, but here is a durable pack for those who stay in civilization but still need the same amount of sturdy protection, for commuting by bicycle or just trekking through the concrete jungle.
