How protective is this backpack?
The Optimal Active Backpack is built for serious protection. A separate tech compartment is equipped with AiroFoam ® impact-absorbing technology, protecting laptops and tablets from drops and shocks. It's also highly water-resistant, keeping your gear safe from rain, spills and splashes – though we wouldn’t recommend submerging it in water. Whether you're caught in a storm or on the move, your tech stays protected.

Is the wet bag included?
No, modular backpack accessories like the Optimal Wet Bag are sold separately. You can purchase them individually or as part of a bundle to customise your setup.
