Zpacks Lumbar Pad
If you need additional support in the lumbar area, this detachable lumbar pad provides extra cushioning by layering over the existing padding. Zpacks Arc backpacks include a full-wrap padded belt. If you need a little extra padding in the lumbar area it can double up the existing padding. The lumbar pad slides on and off the Arc belt as needed (watch video).
