Patagonia designed the Yerba 24L Backpack for the on the go climbers that go directly from class to the crag. Its generous main compartment stores climbing gear, textbooks, or a 60 meter without a problem. Patagonia made the shoulder straps and back panel out of Air Flow mesh for airflow and ventilation. Its fabric comes from recycled bottles, and Patagonia's proprietary DWR coating lasts much longer than standard water resistant treatments. The Yerba also features a padded laptop sleeve that should protect your computer from your quickdraws.
