Field Notes | Pitch Black Rolltop Backpack。ECO-FRIENDLY & WATERPROOF: Made from recycled Ocean Impact Plastic, this backpack is a sustainable choice that\'s also extremely waterproof. Not only is the outside waterproof, but the inside stays dry as well thanks to high-frequency welded seams. SPACIOUS & STRUCTURED: The bag expands and can hold up to 26 Liters. It\'s ideal for everyday use including hiking, especially with the detachable 15” laptop sleeve. Roll the top of the bag down and buckle it up for a trendy look! LIGHTWEIGHT & COMFORTABLE: A lighter version of the original ROLLTOP, the LITE version weighs only 2.2 lbs, being comfortable for everyday use. Extra comfort is added with a padded back and adjustable chest strap. ECO-CONSCIOUS ELEGANCE: Through innovative manufacturing techniques, we give new life to ocean impact plastic. We\'re rewriting the story of fashion with all kinds of high-quality & durable bags, all PETA-approved vegan. MORE THAN JUST A BUSINESS: As a certified B Corporation, we care deeply about making a great impact. Our recycled ocean impact plastic comes directly from our own extensive Indonesian clean-up initiatives, not outside sources.
