The Saigon 3.0 is Onsight's most-featured, and classiest messenger bag yet. This bag is surprisingly light, yet made with Onsight's best, durable materials - heavy-duty, weatherproof tarpaulin and upcycled PET fabric. Both the padded computer sleeve, and the RFID scan-blocking pocket can be accessed without opening the main compartment, and have weatherproof Uretek Zippers.
