The Tasmanian Tiger Tactical Field Book was designed to keep valuable note taking supplies safe and organized when operating in the field. Store all-weather notebooks and pens and give them an extra layer of protection with the rugged Cordura 700D fabric construction that protects against tearing, abrasion, and water damage. The fold out design unzips to reveal several large pockets for note pads or books and smaller inner pockets to store SD cards, conversion and ballistic tables, maps, and more. Measure precise increments and angles with the printed 4 inch/10 centimeter ruler and 180 degree protractor printed on the right side of the main compartment. This case was designed to hold an A6 sized notebook (4.13 × 5.83 inches). It was designed for sniper use, but is ideal for anyone traveling or working outdoors that needs to keep paper, pens, maps, or similar accessories safe and dry, such as construction workers, hunters and trappers, fishermen, hikers, or campers. Ensure high performance and long lasting durability with the main zipper opening that uses industry leading YKK zippers. The Tasmanian Tiger Field Book protects and organizes admin and note taking supplies in harsh environments.
