Mara, Mara on the wall, whos the fairest sling of all? Okay, so Mara probably isnt on a wall. Its on your body, thanks to a fully adjustable shoulder strap. That means your hands are free to do whatever they please—choose a new hot sauce, put hot sauce on wings, put wings in mouth, or maybe something wholesome like knit. With this Neoprene sling, the possibilities are essentially endless because with multiple pockets, card slots, and a D-ring for keys, Mara was made for the essentials.
