"The Patagonia Black Hole 25L Backpack is built around the kind of day that starts at a desk and ends anywhere else. The body fabric is 300-denier postconsumer recycled polyester ripstop with a TPU-film laminate, which gives the pack structure and durability without adding bulk. What Our Gearhead® Experts Are Saying:""I grab this one when I'm heading to the office and then straight to the airport. Everything fits, and the padded laptop sleeve means I'm not digging through the main compartment at security."""
