{"type":"firestarter.listing","listing":{"id":"lst_VdKdZl-S","product_name":"SitLight","category":"Backpack Accessory","description":"Designed specifically to be used in the pad pocket of any of our overnight backpacking backpacks. This multi-use featherlight pad will give structure to your pack, cushion your back and allow some air to circulate between you and the pack while keeping the pack body close to you. The SitLight can also be used to sit on in camp or during breaks, to lengthen your existing sleep pad or as a base for your pillow.\nThe foam is amazingly light and strong for its density. The pads are tough, flexible and resilient, and exhibit good UV stability. As a closed-cell foam they will not absorb water.\nThese are only compatible with our new Mariposa 60 and Gorilla 50 PVT packs. For your small size pack, you will need the 17\" size. For your medium size pack, you will need the 19\" size. For the large size pack, you will need the 21\" size.","images":["https://cdn.shopify.com/s/files/1/1300/6549/products/SitLightPad.jpg?v=1660154406"],"price":13,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:36.150Z"},"share_url":"https://firestarter.network/l/lst_VdKdZl-S","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
