REI offers the Patagonia Yerba 15″ Notebook Backpack in Prickly Pear for $28.93. Shipping adds $5.99, or opt for free site-to-store. (You can also bag free shipping on orders of $50 or more.) Even with shipping, that’s $15 under the lowest total price we could find for this backpack in any color elsewhere. Sales tax is added where applicable. This 22-liter daypack features an interior padded sleeve for laptops up to 15″, stretch-mesh side pockets, and more.
