The Sac is an excellent, all-purpose sleeping bag made using the latest in synthetic fill technology. The Thermolink fill is exceptionally strong, warm and lightweight, encased in a highly breathable, water-repellent and durable 20D Vapour Vent V2 shell. The roomy, tapered rectangular bags are easy to care for and stay warm when wet, with options available in three temperature ratings (ISO 23537.1 limit of comfort -1, -5 and -8°C) in regular and large sizes. The full-length YKK #5 zip has an anti-snag slider and opens at both ends for easy venting.
