The Western Flyer – our carry-on convertible travel briefcase – is now available for pre-order with convertible backpack straps, shipping by late September. Previously, the Western Flyer had been available with a convertible sling strap only. Now you can choose between the convertible sling strap OR convertible backpack straps. What’s the difference between the two? Some folks – especially women – may find the backpack straps to be more comfortable than the sling strap, while others may prefer the quick release and ease of the sling strap. We listened to your feedback and decided (for now) to offer both options.
