Remember Field Notes’ Seasonal Release for the Summer of 2020, the ‘Heavy Duty’ set of work books? Well they were so popular that Field Notes brought them back (sans the included rubber band sadly, but you can still get a pack of those right here). The Heavy Duty is great for keeping on top of lists, sketching or taking notes, thanks to its interesting mix of ruled and double graph grid paper. 
 
The covers are made of a ‘Super Duty Chipboard’ which makes a reliable firm cover, less likely to bend. They have been screen-printed with opaque ink. One in DDC Orange and the other in Blue Sky Blue.
 
The binding has been designed with a sturdy Double O-Wiring, creating a ‘flip’ notion to open each memo book, you can choose to write in the memo books in chronological order or any page you find blank  - don’t be mistaken not to notice that pages are ruled with either 6.4 mm ruled lining and grid graph measured at 3.2 mm.  
 
Each book contains 80 pages, ruled pages in the front and double graph grid pages at the back.
