Following are our 3 sizes of Knack Packs and the corresponding size of laptop (measured diagonally across the screen) that fits in each one.  

Since laptops can still vary greatly by size even with the same screen size, the best way to see which size Knack Pack your laptop will fit into is by adding the length (longest measurement) and the height (usually less than an inch). If the total of these 2 numbers is less than 13", your laptop will fit in a small Knack Pack. If the total is less than 15", your laptop will fit in a medium Knack Pack. If the total is less than 17", your laptop will fit in a large Knack Pack. Please note the closer the total is to 13", 15", or 17", the tighter the fit will be.

Customers who don't want to give up their preferred size of Knack Pack, due to their laptop size, have found storing their laptop in the tablet pocket of the back pack section a simple work around. The laptop is still protected, easily accessible, and the user gets to carry the Knack Pack that fits their needs perfectly.  

Following is a quick chart showing the sizes we offer.

Sure. Following is a quick chart detailing the typical changes of clothes that can fit in a Knack Pack. For detailed comparison, please go to our website: Size Comparison.

The two biggest factors in picking the right size of Knack Pack for you are simply weather and shoes. If you need to pack a really bulky sweater, jeans, and a pair of dress shoes for 1 night, you are probably going to need a Medium Knack Pack. However, if you are heading to the beach for 3-4 days and have shorts, flip-flops and t-shirts, you can grab your Medium Knack. If you are 6’4”, need dress shoes, sweater and corduroys for a 2 night stay, you will probably need the Large Knack for your trip. Shoes are a space-killer for packing (but stay tuned, we are working on a solution!) and we do recommend using our Packing Cubes. You would not believe how much space they save!
