The multi-tasking Chacabuco keeps your Monday-through-Friday trappings organised and accessible and, when you make a break for the wide-open spaces, holds a weekend's worth of outdoor gear. It houses everything in three separate compartments and has reflective piping for night commutes and an exterior shock cord for additional stowage. The generous main compartment carries most things you would need at the office or for a weekend away, and comes with a padded sleeve that's raised to protect up to a 17-inch laptop. Equipped with a tube port, the sleeve also accepts a hydration reservoir (not included) when you leave your laptop at home. A secondary pocket stores everyday necessities like keys, pens and a phone. A zippered outside pocket holds energy bars, and a microfleece-lined top pocket protects sunglasses or an audio device. Two stretch pockets keep water bottles within reach. The Chacabuco's suspension system uses a heat-venting airflow-mesh back panel and shoulder straps, a webbing waistbelt and a sternum strap with an emergency whistle. Compression straps stabilise the load. Made of a 420-denier 100% nylon oxford plain weave, with an 840-denier 100% ballistics nylon bottom. The lining is 200-denier 100% polyester. All fabrics have a Deluge® DWR (durable water repellent) finish.
