The sheet does a similar job to quilt straps but blocks more drafts and is less constricting.  \nWhat is it exactly? It's a hooded half sheet that fits onto your sleeping pad to give you the warmth and comfort of a sleeping bag but the freedom and temperature regulation of a quilt. Sleep like you're in your bed at home!\nNOTE: Designed to be used specifically in conjunction with the Zenbivy Quilts. This is compatible with any Zenbivy quilt regardless of temperature rating, size, color, style, or year. \n_______________________________________________\nSpecs\nLimit/Comfort:\n\n\n\n\n25°: 25°F  / 35°F | -4°C / 2°C\n\n10°: 10°F / 20°F | -12°C / -7°C\n\n\nSizing:\n\n\n20\": Fits mattresses up to 21”W x 42\"L x 3.5\"T  | 53cm x 106cm x 9cm\n\n25\": Fits mattresses up to 26”W x 42\"L x 3.5\"T | 66cm x 106cm x 9cm\n\n\n**See the Zenbivy Sleep System Sizing Guide for more information\n\n\nWeight:\n\n\n25° Down:\n\n\n20\": 5.4oz | 153g\n\n\n25\": 5.7oz | 162g\n\n\n\n\n10° Down:\n\n\n20\": 6.4oz | 181g\n\n\n25\": 7.1oz | 201g\n\n\n\n\n25° Synthetic:\n\n\n20\": 8oz | 227g\n\n\n25\": 8.6oz | 244g\n\n\n\n\nFill Weight:\n\n\n25° Down:\n\n\n20\": 1.6oz | 46.5g\n\n\n25\": 1.6oz | 44.5g \n\n\n\n10° Down:\n\n\n20\": 2.9oz | 84g\n\n\n25\": 2.8oz | 79g\n\n\n\n\nMaterials:\n\n\nFills: \n\n\n900+ FP ExpeDRY™ Muscovy Down (90/10 grey duck down), water-resistant treatment (chemical-free, PFAS-free)\n\n\n900+ FP ExpeDRY™ Goose Down (90/10), water-resistant treatment (chemical-free, PFAS-free)\n\n\nPrimaloft® Gold 1-1001 synthetic insulation (100gsm x 2 layers)\n\n\n\nShell &amp; Lining: 10D Pertex® Quantum 280x250T, coating-free, cire, flourocarbon-free DWR, 26gsm\n\n\n\n\n\nSide Wing Panels: 15D Nylon Taffeta Coating-free, non-cire, C0 DWR (PFAS-free), 33gsm\nMade in Vietnam\n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0537/1177/files/UltralightSheet.jpg?v=1721080563","https://cdn.shopify.com/s/files/1/0537/1177/files/Hood_clips.jpg?v=1721080574","https://cdn.shopify.com/s/files/1/0537/1177/files/Ultralight_Sheet_by_Zenbivy_1.jpg?v=1750868112","https://cdn.shopify.com/s/files/1/0537/1177/files/Ultralight_Sheet_by_Zenbivy_2.jpg?v=1750868118","https://cdn.shopify.com/s/files/1/0537/1177/files/Ultralight_Sheet_by_Zenbivy_3.jpg?v=1750868127","https://cdn.shopify.com/s/files/1/0537/1177/files/ULSheetClip.jpg?v=1721080564","https://cdn.shopify.com/s/files/1/0537/1177/files/Ultralight_Sheet_by_Zenbivy_4.jpg?v=1750868137","https://cdn.shopify.com/s/files/1/0537/1177/files/Ultralight_Sheet_by_Zenbivy_Primaloft_Synthetic.jpg?v=1768421582","https://cdn.shopify.com/s/files/1/0537/1177/files/Ultralight_Sheet_by_Zenbivy_Primaloft_Synthetic_close.jpg?v=1768421534","https://cdn.shopify.com/s/files/1/0537/1177/files/Zenbivy_Which_down_is_right_for_you_chart.jpg?v=1772814517"],"price":139,"currency":"USD","in_stock":true,"inventory_qty":99990,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:44.289Z"},"share_url":"https://firestarter.network/l/lst_B43qO6h4","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
