Shoulder Strap Pads, Soft Air Cushion Replacement Pad, Reducing Shoulder Load, for Backpack, Schoolbag, Travel Bag (1 Pair, S)

Bought two for my backpack and my shoulder still hurt from using this product. The pain level only dropped a little compare to not using this product so it doesn’t work. I would say the shoulder pain level dropped from a 8/10 to 6/10. Still on a hunt for a better product.
