The Pakt One v3.1 Travel Backpack is a carry-on travel backpack designed for travellers who want flexibility without sacrificing organisation. Despite its expandable design, which increases capacity from 35 to 40 litres, its dimensions of 52 x 34 x 23cm (fully expanded) sit well within most airline size limits. The pack weighs 1.81kg (including hip belt).

The backpack is made from durable ballistic nylon with a PFC-free water-resistant finish and is backed by Pakt's Lifetime Warranty. The adjustable harness, removable hip belt and multiple grab handles provide several comfortable carrying options, while lockable YKK zippers, external attachment points and luggage pass-through enhance its practicality when travelling.

The Pack One has a split-case design that may not suit everyone. Its laptop compartment sits within the centre divider. While this protects your laptop more, it doesn't sit against your back, and thus weight distribution is not optimal. It also provides only a single water bottle pocket.
