{"type":"firestarter.listing","listing":{"id":"lst_hsmFeQqw","product_name":"Arc Zip Ultra 62L Backpack","category":"Backpacks : Frame : Arc Frame","description":"First time I put on the Arc Zip Ultra 62L, I immediately noticed the difference—this was the best pack fit I’ve ever experienced. I thought my previous packs fit well, but the extra adjustability of the shoulder straps and hipbelt tilt on this model really took comfort to another level. 10kg has never felt this comfortable before. Highly recommended!\n– Kasper A., ★★★★★\nThe Arc Zip Ultra was built from the ground up for hikers who need quick access to their gear and all-day comfort on the trail. The front zip panel lets you grab your food bag or camera gear without digging through your pack. Our signature curved carbon fiber Arc Frame transfers weight to your hips and creates a breathable space between your back and the pack. No more sweaty discomfort during long climbs or hot days.\nWith a patented adjustable torso height, interchangeable shoulder straps, and a padded belt that hugs your shape this ultralight pack is ready to move with you wherever the miles take you.","images":["https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-hero-duskblueb.webp?v=1753969851","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-0526-ArchHaulZip-SuitcaseMode-1.webp?v=1779806357","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-standardstrapsacrosschest-male-rear3qtr.webp?v=1753969851","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-hero-stormgreyb.webp?v=1753969851","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-hero-jetblackb.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-standardstrapsacrosschest-male-frontb.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-front.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-standardstrapsacrosschest-male-front3qtr.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-standardstrapsacrosschest-male-leftprofile.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-standardstrapsacrosschest-male-rear.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-standardstrapsfullypacked-male-rear3qtr.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-rear.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-upper-attachments-1-blue.webp?v=1749500641","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/Zpacks-BackpackOvalCarabiner-1b.webp?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-60L-smallstraps-rear3qtr_2048xb_2048x_b0cbac4a-3ccb-4ea7-9265-7dafe082b06f.png?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-40L-smallstrapsacrosschest-male-frontb_e238a257-e576-42f2-b369-9ffcbe2fb926.webp?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-40L-smallstrapsacrosschest-male-front3qtr_9d2ef577-29a1-4152-9f19-54d64ef89cde.webp?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-60L-standardstraps-rear3qtr_2048xb_2048x_fcaba67b-1223-4914-8676-61c5fc8e5f98.png?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-60L-veststraps-rear3qtr_2048xb_2048x_56d43ba4-032b-4b10-9003-a1a27cce6e97.png?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-veststrapsacrosschest-male-frontb.webp?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-veststrapsacrosschest-male-front3qtr.webp?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-60L-veststraps-male-phonepocket_2048x_4b1dc3de-e726-4c1e-bdf7-0026f8bbf6ca.png?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-60L-veststraps-male-snackpocket_2048x_ca546993-4c28-4550-ad32-c0c43b649bac.png?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-haul-ultra-60L-veststraps-male-waterbottle_2048x_7b034012-8e32-4f7a-b22f-b15979670587.png?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-arc-zip-ultra-62L-hip-attachment.webp?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-40L-50L-60L-62L-bearcanister-1_2048xb_2048x_9f2fe128-5d03-4eea-b52c-bbe7eeaedcf8.png?v=1753471226","https://cdn.shopify.com/s/files/1/0004/4652/9572/files/zpacks-40L-50L-60L-62L-drinking-tube_2048x_5def6468-06f3-4b84-ab0c-f032621ad392.png?v=1753471226"],"price":449,"currency":"USD","in_stock":true,"inventory_qty":1079892,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:38.883Z"},"share_url":"https://firestarter.network/l/lst_hsmFeQqw","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
