Our first backpack, this bag is a timeless design that's ready to be put through its paces. Boasting a dedicated laptop pocket and plenty of space, it's got room for all of your essentials. It starts crisp and character is woven in with every day of carry.\nWe held it to our leather standards. The shell is cut from heavyweight, water-repellent 18 oz field-grade twill, finished at the touchpoints with full-grain Horween leather, and secured with solid brass hardware. Heavy duty zippers keep things moving smooth. Padded straps and a structured back panel make all-day hauls easy. A quick wipe brings it back to sharp. Made in the USA.\nDimensions: 16”(H) x 12”(W) x 4”(D)\n\n\n18 oz field-grade canvas in Field Green or Desert Tan\n\n\nWater-repellent twill built for real-world travel\n\n\nFull-grain Horween leather straps and trim\n\n\nSolid brass hardware\n\n\nPadded shoulder straps and supportive back panel\n\n\nDedicated laptop sleeve with interior organization\n\n\nTop grab handle for quick moves\n\n\nWipe-clean care\n\n","images":["https://cdn.shopify.com/s/files/1/0007/3223/3783/files/CanvasBackpack_1_2.jpg?v=1760727951","https://cdn.shopify.com/s/files/1/0007/3223/3783/files/CanvasBackpack_Khaki_1_52b3877c-f409-49da-9f30-908093244671.jpg?v=1763426553"],"price":450,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:51.007Z"},"share_url":"https://firestarter.network/l/lst_kxkxCx2R","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
