The Mezzo Laptop Backpack is all I need to take my 16-inch MacBook Pro, iPad, accessories on the road

Apple World Today - January 27, 2020

“The WaterField backpack isn’t inexpensive. But you’ll be hard pressed to find one that’s more rugged, easier to use, and which is as handsome.”

5/5 Stars


The full-sized Field Sling and compact-sized Backpack are ideal for people of smaller stature and can carry enough gear for a day's outing.

  1. The built-in Tablet/Laptop Padded Sleeve fits devices up to 12.75" x 9.25, including:
    • MacBook Pro (13")
    • iPad Pro w/ Magic Keyboard (11" & 12.9")
    • Surface Book 2 (13.5")
    • Surface Laptop 3 (13.5")
  2. The main compartment expands to fit items you may need throughout the day like a jacket, hat, scarf, etc.
  3. The front pocket holds easy-to-access small items like your phone or keys.
  4. The pleated side pockets expand inward to hold bulky items. It's just the right size for stashing the Nintendo Switch Lite.


Step 1: Optimize the size, shape, and form so it sits comfortably on your back. 


Step 2: Include organizational and easy-access features for essential items.


Step 3: Personalize the strap options to maximize individual comfort. 


We designed the Field Sling and Field Backpack to carry and organize the gear you'll need for a day of exploration. 






The Field Sling strap attaches to heavy-duty D-ring and pivots as your body moves, keeping the Sling stable on your back for a more comfortable, ergonomic fit. 


Choose the right or left side to carry your Field Sling.  Simply unhook the strap from the bottom D-ring and re-hook it to the side that you prefer.  


Each WaterField Sling is tailored to fit your gear and body type. All are comfortable, lightweight and compact. Choose the style that best meets your needs and individual preference. 


The full-sized Field Sling is a bit deeper than the slim Sutter Tech Sling, while the Sutter Sling Pouch is the smallest of the three.  


The Field Backpack is designed for people of medium stature, and its compact size can hold 13-inch laptops. 


The thinner, somewhat taller Sutter Slim Backpack has two padded compartments for carrying a laptop and tablet, while the mid-size Mezzo Laptop Backpack is slightly deeper than both and also has two padded device compartments.





You can keep your bag looking new by reapplying wax when you think it needs a little refresh. Although others will work, you can use Martexin Original Wax — the original wax used on your Waterfield canvas bag.
