With Ergo-Tech Sensitivity, the KTA44V Kata backpack has your...back! This pack won't stress or strain your back as much as the typical setup does. It is made to be comfortable while carrying.
With a Flexi-Shield technology, explained on the site:
This high frequency molded flexible reinforcement appears in the form of ridges on the exterior of the safe guard zones for ultimate protection.
And the Elasto-Guard that says it is made of three layers with different uses. It has anti-scratch cushioning as well for extra durability. It includes media pouches, water bottle holders, 15" laptop space and much more. Take a peek at the details of this and look at the price of $88.95 that seems quite fair for the features.
