COMFORT/FIT
The Timbuk2 Tuck provides decent overall comfort while carrying light loads for distances shorter than six miles. The addition of a laptop helps stabilize the pack on the back. 

While the Timbuk2 Tuck does not offer a hip belt, its shoulder straps contain enough padding to make them comfortable under moderate (ten pound) loads. 

The back panel conformed to our tester’s back, making the pack relatively comfortable even with a laptop inside. However the lack of breathability in the back panel during long distance rides in hot, humid weather will decrease comfort. 

Mindfulness is needed when packing. Because of the minimal padding on the back panel, objects that are hard with sharper edges will poke through and reduce comfort. When the pack is full of bulgy items like groceries (without any soft items like clothing to buffer) the pack will be uncomfortable and is likely to slide around on the wearer’s back. 

STABILITY
Despite the lack of a sternum strap, the Timbuk2 Tuck is a moderately stable pack when only carrying a laptop. Our tester found that the weight of a laptop helped keep the pack centered on her back. However when the pack was loaded with groceries, the pack did not lay flat on her back and slid to the left or right. 

STORAGE
The Timbuk2 Tuck pack offers twenty liters of cargo capacity. Inside the main compartment is an organizer pocket and a minimally-padded laptop sleeve that can hold up to a seventeen-inch laptop. The laptop sleeve is also accessible via an exterior side zipper; however, the zippered opening is too small to insert or extract a laptop that is larger than fifteen inches and the padding is so minimal that accidentally dropping the bag could damage a laptop.

A zippered stealth pocket on the side can hold small, flat items like cash or identification. On the Timbuk2 Tuck’s exterior is a secure zippered pocket that works well for holding a bike lock, wallet or other items that need to be accessed quickly. 

The Timbuk2 Tuck also has two unsecured side pockets but our tester found their use limited. They are too tight to hold a one-liter water bottle or bike u-lock. 

DURABILITY
The Timbuk2 Tuck is constructed with a lightweight durable polyester fabric. The zippers are large and sturdy however the single plastic buckle that secures the roll-top to the pack is made from a lightweight plastic that feels cheap and force is needed to buckle it securely. The Timbuk2 Tuck also comes with a lifetime warranty from Timbuk2.

EXTRAS
The Timbuk2 Tuck offers a few options for reflectivity, such as a vista loop on back to hold a safety light and wide, glove-friendly reflective zipper pulls. 

Our tester found that she could slip the pack off her left shoulder and swing pack in front of her and access this zippered pocket as well as the internal contents of the pack via the pack’s large side zipper.
