Most of our backpacks and bags are designed to sit comfortably beneath the seat on the majority of airlines, while a few of our larger silhouettes are better suited to the overhead bin. You'll find exact measurements under the "Size & Weight" tab on this page. As baggage allowances vary by airline and fare, we always recommend checking your carrier's specific policy before you fly. Our softgoods are built to flex and compress, so packing thoughtfully — and steering clear of rigid, stiff items — makes it easier to fit your bag under the seat when space is tight.
