How can the Aeronaut 45 be carried?
The bag supports three carry modes: backpack, shoulder bag, and duffel. Its shoulder straps can be stowed when not needed, and the product page also describes a cushioned grab handle. This lets the carrying method change between transit, walking, and hand carry.
What are the Aeronaut 45's capacity, dimensions, and weight?
Tom Bihn lists a 45-liter capacity, equivalent to 2,700 cubic inches by ASTM Standard Measure, with dimensions of 21.9 by 14 by 9.1 inches. Listed weight varies by fabric: 3 lb 1 oz for 1050D ballistic nylon, 2 lb 15 oz for 630D ballistic nylon, and 2 lb 10 oz for 420D Spectron.
How is the Aeronaut 45 organized inside?
The main compartment has a wide U-shaped opening. Two expandable end pockets can be used with their dividers to separate items such as shoes or laundry, or opened into the central space. Two quick-access pockets provide room for small essentials such as a phone, wallet, passport, keys, or a small water bottle.
Are the Aeronaut 45's fabrics and zippers waterproof?
No. Tom Bihn describes its fabrics as highly water resistant, with urethane coating inside and a water-repellent treatment outside; the bag also uses water-repellent YKK zippers. The company cautions that seams can leak in significant weather, so this is not a waterproof construction. It says water-repellent qualities can be renewed with Nikwax.
What materials and zippers does the Aeronaut 45 use?
Depending on the selected version, the exterior uses 1050D or 630D high-tenacity ballistic nylon, or 420D Spectron. The page lists 200D Halcyon or 210D Cerylon ripstop nylon linings. Main and side pockets use #10 YKK Racquet Coil water-repellent zippers with lockable sliders; interior divider zippers are #5 YKK Vislon molded-tooth zippers.
What guarantee does Tom Bihn provide for the Aeronaut 45?
Tom Bihn says its products are satisfaction guaranteed. If a defect in materials or workmanship is found within 60 days of purchase, the company says it will exchange the product free of charge. For problems beyond 60 days that are the company's fault, it says it will repair the item without a repair charge; repairs for normal wear may involve a fee.
Where is the Aeronaut 45 made?
The product specification identifies the Aeronaut 45 as made in Seattle, Washington, USA. That origin statement applies to the bag described on the product page; fabric and lining options vary by the selected color and variant, so buyers should check the specific configuration for its material details.
