{"type":"firestarter.listing","listing":{"id":"lst_6nzt2qWX","product_name":"Ventum Wind Shell by Zpacks","category":"Jackets","description":"\nShips in 1-2 business days | Based in West Melbourne, FL | Est. 2004\nChoosing the right layer for crisp spring mornings and chilly fall nights can be a challenge. Zpacks' Ventum Shell is crafted to cut the breeze and trap warmth in your base layer or against your skin.\nVentum fabric strikes the right balance between cutting cold wind while still allowing enough breathability for sweat to escape when hiking on chilly mornings and evenings. It’s perfect for when a base layer alone is not enough, but insulation would make you overheat. Weighing under 2oz, this is a must-have item for when you plan to hike in cool weather.\nFeatures:\n\nElastic at the back hem and wrists to keep the wind out\nElastic at the hood for a snug fit around your face\nFabric is tightly woven and heat calendared to cut the wind\nC0 Durable Water Repellent to resist rain spray and body moisture. C0 DWR contains no PFOA or PFOS.\nMosquito proof\nHighly wind resistant\nExcellent vapor transfer/breathability - comfortable to wear, not clammy\nSoft feeling - not sticky or plasticy like some other fabrics in this weight range\nRipstop / tear resistant\nLightest weight wind shell available with a hood and full-length zipper\nPacks down tiny into an integrated storage pocket\nAll Zpacks gear has a two-year limited warranty against defects in materials or workmanship\n\n\nFit: Sized for a few inches of wiggle room for layering. \n**Zpacks has updated the elastic on the hoods and wrists to be a black elastic, as shown in the photos. As we move through inventory, you may receive the old version, which has an elastic cord sewn in. Both have the same quality but a minor aesthetic difference. \n\n_______________________________________________\nSizing:\n\n\n\n Size\nChest Girth\nFront Length\nBack Length \nWaist\nBottom Hem Girth\nSleeve Length \n\n\nSmall\n42.5\" | 108cm\n28.5\" | 72.5cm\n29.5\" | 75cm \n40.1\" | 76cm\n42.1\" | 107cm\n27.8\" | 70.5cm\n\n\nMedium\n44\" | 112cm \n29.4\" | 74.5cm\n33.4\" | 77cm\n41.8\" | 106cm\n43.8\" | 111cm\n28.1\" | 71.5cm\n\n\nLarge\n4","images":["https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_black_worn_3.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn_3.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn_7.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn_4.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_packed_size.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_sleeves.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_fabric_close.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_zipper.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn_2.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn_6.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn_5.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_blue_worn_8.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_black_worn_2.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_black_worn.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_black_worn_5.jpg?v=1774886503","https://cdn.shopify.com/s/files/1/0537/1177/files/Ventum_Wind_Shell_by_Zpacks_black_worn_4.jpg?v=1774886503"],"price":119.95,"currency":"USD","in_stock":true,"inventory_qty":69993,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:44.575Z"},"share_url":"https://firestarter.network/l/lst_6nzt2qWX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
