Know before you buy
Yes, the Stone Travel Backpack Optimal is designed to meet standard cabin-size requirements for most major airlines. Its dimensions are 550mm x 350mm x 200mm, though you should ensure it is not over-packed when expanded to the full 45L capacity.
The tech compartment is lined with AiroFoam®, a specialized material engineered to absorb impact and dissipate energy from drops or shocks. It is specifically designed to keep a laptop up to 16 inches secure during transit.
The bag is constructed from 840D ballistic nylon with a water-resistant coating, which provides excellent protection against rain and splashes. While it is highly weather-resistant, it is not fully submersible, so it should not be submerged in water.
Yes, the full clamshell opening functions like a suitcase, allowing you to lay the bag flat and access your entire contents at once. This makes organizing clothes and gear significantly more efficient than digging through a top-loading compartment.
The backpack features an integrated expansion system that increases the internal volume from 40L to 45L. This provides extra depth for bulkier items, though keep in mind that expanding the bag will increase its overall profile.
The backpack is designed with multiple carry modes and an included hip belt to help distribute weight effectively across your frame. This makes it much more comfortable for navigating airports or walking between transit hubs compared to a standard carry-on.
