Review on NEPAK Shoulder Pad Air Cushions: Relieve Shoulder Pain with 2 Pack Replacement Pads for Bags, Guitars, and Straps by Bill Kodba

I bought this primarily for use with a small unpadded backpack. The width is quite wide and it's better to use regular sized straps as they can make my small backpacks look a little awkward. However, this could have been a mistake on my part as I didn't take the measurements into account. I still love them and find them useful for my other bags! I used them on one of my backpacks during a hike (4 hours) and my shoulders didn't hurt much. Perfect for what I need.
