Main materials
840D ballistic nylon: Highly durable and abrasion-resistant for long-term use.
Triple-layer PU and PC coating: Provides added strength and water resistance.
420D recycled nylon side panels: Lightweight and tough.
210D nylon lining: Smooth, protective interior.
AiroFoam^® in tech compartment: A non-Newtonian, impact-absorbing technology designed to protect larger tech devices from drop damage. It’s made up of intelligent molecules that rush together upon impact, forming hydrogen bonds that temporarily break and consume significant amounts of energy that would otherwise impact your device.

PU-coated YKK zippers: Durable, smooth-gliding and water-repellent.

How protective is this backpack?
The Optimal Travel 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.

Are the accessories included?

No, modular accessories like the Optimal Compression Wardrobe are sold separately. You can purchase them individually or as part of a bundle to customise your setup.

Can I use this backpack as a cabin bag?
Yes! At its standard 40-litre capacity, the Optimal Travel Backpack meets the cabin bag size requirements for most major airlines and fits in overhead bins. While we've thoroughly compared its dimensions with airline guidelines, we can’t guarantee compliance in every case due to airline-specific policies. It’s not designed to fit under the seat as a personal item.
