• Heavy duty, solid brass YKK zipper
• Stitched with the same thick marine-grade, UV resistant thread used on all of our solid leather bags and briefcases.
• Full grain, USA sources 100% cowhide leather. This is mixed tanned leather meaning it's vegetable tanned and then finished with a chrome tanning process. This process gives the leather its 'vintage' look and feel. 
• Full length, adjustable, solid leather shoulder strap with shoulder pad. Strap also has solid brass hardware and utilizes "dog leash" style clasps to affix it to the solid brass d-rings on the Explorer Briefcase.
• Solid leather handles feature a double snap closure to secure them together making it easy to carry when on the go. 
• The bag also features a solid leather flap designed to slip between the handles and over the top of the briefcase's zipper. This flap snaps into place to help the briefcase keep its shape easier during transit.

The Explorer Briefcase is full of useful features designed to keep you organize on the go with all of your vital widgets and gear easy accessible.

• Main compartment will easily accommodate a 13" MacBook Air, MacBook Pro or other similarly sized laptops. The internal compartment is approx. 14.75" in length. We encourage you to grab a ruler or tape measure or use Google to search the case dimensions of your laptop(this is what we do to answer your question). If the laptop dimensions are smaller than the dimensions of the bag, it will most likely fit. :) 
• Internal side compartments are ideal for paperwork, tablets, books, or journals.
• Inside you'll also find several leather pockets and two pen slots.
