For school, play, or travel, the Patagonia Refugito 18L Day Pack has our kids' backs. Its 18-liter capacity is great for day trips and vacations while the PU coating and durable water repellent finish add abrasion-resistance and moisture-resistance for long-term wear. As with most Patagonia products, the pack includes many recycled materials to conserve resources and has been sewn in a Fair Trade Certified facility to pay workers a premium for their labor.
