FROM THE MANUFACTURER The new Cramer Tuf-Tek line Incorporates the latest in materials, technology and design making them the most durable and functional kit on the market. Multiple layers of external storage create spaces that are more organisable and accessible so you can quickly find what you need, when you need it. Rigid supports have been added to the main walls of the bag for integrity, support and protection. It also helps the bag keep its shape and keep it looking new. This bag's ergonomic rounded corner design gives a large square bag a more aerodynamic and sleek look. Also new to the Tuf-Tek line are the single pull zippers which allow for quicker, easier access and a gradual turn around corners which increases zipper life by reducing wear and tear.
