Our Yerba opens as fast as the twist off on a cold one. This streamlined backpack has a zippered, top loading design for easy access to the main compartment so you can get at your gear quickly. Sized to hold everything you need for a full day on the trail, the Yerba also features a padded, raised computer sleeve doubles as a hydration pocket to protect most 15 laptops when you're cruising through town. A zippered stash pocket on the lid keeps your small essentials within reach and two stretch woven side pockets carry water bottles or your hat and gloves. The Air Flow mesh shoulder straps and back panel breathe for comfort on the long, hot haul. Made from 450 denier recycled polyester plain weave, with a 450 denier recycled polyester ripstop bottom. The lining is 200 denier 100% polyester. All fabrics have a DWR durable water repellent finish.
