They are suitable for extreme cold or sub-zero temperatures
Sea to Summit is an Australian company headquartered in Perth, Western Australia. The company manufactures sleeping bags using materials sourced from across the globe, with final assembly taking place in Vietnam, China, and Taiwan.
Sea to Summit's range of sleeping bags is designed to keep users warm and comfortable in various outdoor adventures, from backpacking to camping and even extreme cold or sub-zero temperature expeditions. The sleeping bags are made from high-quality materials, including RDS-certified premium down, bluesign® certified fabrics, and non-PFC finishes.
The down used in the sleeping bags provides superior warmth for its weight, allowing the bags to be lightweight and easily packable while still providing sufficient warmth for extreme cold or sub-zero temperatures. The higher the down loft power, the smaller the packed size and the better the warmth-to-weight ratio. Sea to Summit's down sleeping bags are engineered with body mapping and ergonomic shaping to ensure the right amount of insulation is placed exactly where it is needed. Additionally, the down is independently certified (IDFL) for its quality and fill power, and the bags feature a premium high lofting RDS-certified ULTRA-DRY Down.
Sea to Summit's zero-degree sleeping bags are specifically designed for adventurers who brave the harshest conditions, offering unparalleled warmth and protection. These bags are crafted with durable, weather-resistant materials and thoughtful design features to ensure superior comfort and protection. The Alpine series, for instance, is designed for high-altitude expeditions, while the Ascent series offers a blend of warmth and adaptability.
To achieve the desired temperature rating, it is important to consider the sleeping pad used in conjunction with the sleeping bag. An adequate insulation layer underneath is crucial, especially in cooler seasons when the ground is colder than the air. Sea to Summit recommends an R-Value of 5 or greater for winter use to ensure the sleeping bag performs optimally.
