The Secret Zipper Pocket Isn’t Broken—It’s Brilliant

Why is the secret zipper pocket on my flap only accessible when I insert things upwards and completely stitched shut at the bottom?

Well, the answer is in the question—it’s a “secret pocket.” Zipper pockets are typically designed for inserting items downward, as that’s the natural movement for your hand. Because this zipper pocket is meant to be discrete and hidden, it functions in the opposite way, making it accessible only when you insert things upwards and completely stitched shut at the bottom.
