{"type":"firestarter.listing","listing":{"id":"lst_68tcKGwQ","product_name":"Picketpost Rack-Top Bag","category":null,"description":"The Picketpost is our top-opening, kitchen-sink throw-it-all-in-there rear rack-top bag! Designed to be easily accessed on the go, without losing the dropper compatibility and stability that our bags are known for.\nThe Picketpost attaches to your rear rack with four short TPU straps on the corners, and then the rolltop closure also cinches down directly to the rack. Choose between cam-locking g-hooks for easy access, or Austere Mfg Buckles for the ultimate in USA-made durability.\nThe Picketpost is seam taped for maximum water resistance, which makes it Pretty Darn Close to Waterproof. It's possible for a small amount of water to enter at the corners or through the rolltop, but not enough to ruin your day.\nThis bag is rack-specific, so make sure you order the correct width! The wide version will fit the Old Man Mountain Elkhorn and the Tumbleweed T-Rack, and the narrow version will fit racks from 3.5-4\" wide, including the Mica Rat Tail.\nNeither version will fit the rack on the Trek CheckOUT - but our Elden Rack-Top Bag will fit!\nOne last thing - the Picketpost is not a good choice for packing a sleeping bag, or other item that will try to expand as you stuff it inside. For that you want a bag with a narrower opening to provide more friction, like our Elden Rack-Top Bag.\nSpecs\n\n\n\n \nNarrow\nWide\n\n\nVolume\n12 Liters\n14 Liters\n\n\n\nLength at base\n\n12.5\"/320mm\n12.5\"/320mm\n\n\n\nWidth at base\n\n4\"/100mm\n6\"/150mm\n\n\nWeight (EPX200 Fabric)\n8.5oz/235g\n9.5oz/265g\n\n\n\n \nNote: The wide version of the Picketpost does not have attachments to fit a narrower rack. This is by design, because during testing we found that using a bag that's much wider than the rack it's on is a recipe for a floppy, unstable experience.\nPicketpost vs Elden\nNeed help deciding between our rack-top options? The difference mostly comes down to what you want to carry, and when you want to access it. Both bags have roomy mesh pockets to store quick-access items, but for the main compartment there are large differences","images":["https://cdn.shopify.com/s/files/1/0610/6529/8090/files/picketpost-rack-top-bag.jpg?v=1778299419","https://cdn.shopify.com/s/files/1/0610/6529/8090/files/picketpost-lunch-bag-closure-2.jpg?v=1778299429"],"price":150,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:43.024Z"},"share_url":"https://firestarter.network/l/lst_68tcKGwQ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
