Apart from having a very unique name, the Chacabuco Backpack is
Patagonia's largest daypack for those who can't leave gear behind. This
big backpack boasts two generous main compartments, one with a padded
sleeve for most 17-inch laptops. The padded sleeve also doubles as an
insulated sleeve for reservoirs thanks to the integrated tube port.
Breathable, padded mesh makes sure the back panel and shoulder straps
are comfy on or off the trail. Patagonia made the Chacabuco out of a
highly durable recycled polyester with a DWR coating for superior
water-resistance. This pack also features a zippered pocket for quick
access to essentials, small pockets for sunglasses and car keys,
stretch-woven pockets for water bottles, and shock cords for bulky items
like an extra layer.
