After a couple of long trail days I am happy to report it works as advertised. It’s worth the money. The thing I like most about it is it’s thick enough to shine under heavy load while remaining thin enough to go unnoticed on a light carry. It adds versatility to an already great pack. I don’t have any thoughts on how this could be improved currently.\n– Kevin G., ★★★★★\nOur Arc backpacks include a full-wrap padded belt. If you need a little extra padding in the lumbar area our detachable lumbar pad can double up the existing padding. The lumbar pad slides on and off the Arc belt as needed.\nThese are NOT compatible with our frameless backpacks.\n ","images":["https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-lumbarpad.jpg?v=1682369227","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-01-2026-LumbarPad-16.webp?v=1769105851","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/DSC09915.jpg?v=1769105851"],"price":24.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:39.401Z"},"share_url":"https://firestarter.network/l/lst_90YQLFL8","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
