The Techonaut 30 is a 30L carry-on travel backpack designed for maximum airline compatibility and all-day comfort. Inspired by the original Aeronaut, it combines three carry methods — backpack, shoulder bag, and duffel — with smart organization and a breathable skeleton back panel for improved airflow. Three carry options let you wear it how you want. Backpack, duffel, or shoulder bag — with stowable shoulder straps and a cushioned grab handle that stay out of your way when you don’t need them. Breathable skeleton back panel with soft mesh adds comfort without trying too hard. Airflow where you want it, structure where you need it. Three quick-access pockets for having the necessities close at hand. Good for your phone, wallet, passport, keys, or a small water bottle. Main compartment opens wide, U-shaped style. Easy to pack, easy to find what you’ve packed, even when you’re on the move. Expandable end pocket with removable divider. Keeps shoes or laundry separate, or open it up for one big space with the internal zipper. Your call. Edgeless shoulder straps engineered with long-haul comfort in mind. Luggage passthrough slides over your rolling bag handle. Makes airports and train stations a little easier, one less thing to carry. Suspended laptop compartment with exterior access that fits 16” laptops or tablets.
