Knack Convertible Duffel [Review]

Convertible. Expandable. Great organization. This is the Knack Convertible Duffel in a nutshell.

Inside the main compartment of the Knack Convertible Duffel you are greeted with lots of pockets to organize your tech and travel items. A fleece lined zippered pocket protects glasses and tech from scratches while another fleece lined slip pocket gives you a safe spot for a tablet. One of the more interesting design choices are the small elastic bands that allow you to attach pens, charging cables and smaller accessories. Unlike traditional pockets, these elastic bands take up little room when not in use.

Knack goes above and beyond with designing their travel bags around airline size requirements so that you can stay compliant no matter how you decide to carry the the bag. The packing area of the Convertible Duffel starts compressed at 24 liters which is enough room to pack for a weekend while keeping the bag small enough to store under most airplane seats. 

The expanded 40 liters allows you to pack for around of week of travel while still falling under most airline carry on size requirements. To put the Convertible Duffel’s size into context, 40 liters is around the same capacity of many carry-on rolling luggage.

Switching between duffel and backpack on the Knack Convertible Duffel is one of the simplest mechanisms we’ve seen in a convertible backpack yet. Knack uses a combination metal D-rings and a simple clip mechanism on their shoulder straps. There is no fidgeting with complicated locks or special straps like with other convertibles. The shoulder straps can be tucked into a special zippered pocket on the back panel when it’s time for duffel carry and the entire process takes seconds and can be done easily on the fly.

Despite its unassuming appearance there are a few sneaky pockets on the exterior of the Convertible Duffel that aren’t obvious at first glance. The first is an internal water bottle pocket that safeguards your drinking bottle from contaminants while providing a cleaner profile. 

Against the back panel is where you’ll find an external 15-inch laptop compartment. Our one gripe with the Knack Convertible Duffle is that although the main compartment includes a zipper that be locked with a TSA lock, the laptop compartment does not. In an ideal world we would be able to lock down both compartments.

After all is said and done the Knack Convertible Duffel is a beast of a travel bag with some great features that just aren’t found in other travel backpacks. It’s versatile enough that it really might be the only travel bag you’ll need. We recommend it for frequent flyers or business travelers who need a bag they can count on for short and long trips alike.

What we like

• Clean minimalist design with tons of hidden features

• Great internal pocket placement for organization

• One-bag - expandable and convertible design makes the Convertible Duffle incredibly versatile

• Anti-microbial treatment on inside lining to help combat smells

Knack Pack Series 2

The Knack Series 2 expandable backpack is the newest update to the best selling Knack Pack - a daily backpack that expands into an ultra-functional travel pack.

With the Series 2, Knack has managed to keep the best parts of the original Knack Pack and add killer features such as more internal organization, improved security and a brand new streamlined look.

What sets the Knack Pack Series 2 apart from other hybrid bags is that it doesn’t compromise on daily carry features. Inside you’ll find a generous main compartment that is separate from the travel compartment, a new front internal organizer compartment and separate laptop compartment. We love how the expandable travel compartment is out of the way until you need it.

What we like

• Top-notch materials like the full grain napa leather give this backpack a premium, and dare we say luxurious, feel.

• For an expandable backpack the Knack Series 2 is surprisingly lightweight. When compressed, it’s about the size of a regular 24L daily backpack with little extra bulk.

• Amazing pocket variety for both everyday and travel items. The daily main compartment is separate from the expandable travel compartment for a true convertible backpack experience.

What we DON’T like

• We love the hidden side water pocket but unfortunately you will be limited to only storing slimmer bottles. Wider bottles, like a 32oz Nalgene bottle or larger Yeti tumbler, will not fit.

SPECIFICATIONS

• Dimensions: 19"H x 12"W x 4.5"D (unexpanded)

• Capacity: 24L-35L

• Material: Water resistant 420D Nylon or Polyester Ottoman Fabric. Full grain Napa leather touch points.

• Weight: 3lbs

• Laptop Compartment: Up to 15”
