Technologies and manufacturing processes

  • 850+ LOFT ULTRA-DRY DOWN

    "The second highest fill power in all Sea to Summit sleeping bags and quilts. 850+ Fill Power means that one ounce (30g) of down expands to over 850 cubic inches after compression. A higher loft means that less down can be used to achieve the same temperature value - important for high-performance sleeping bags."
  • QUILTLOCK SYSTEM

    "The QuiltLock system uses the snap closures on the shoulder and foot ends of Sea to Summit sleeping bags and the quilt box /quilt straps to secure your quilt to the sleeping bag. This increases the thermal performance and versatility of your sleeping system": "Your integrated quilt is therefore suitable for ultralight summer adventures on the one hand and turns your three-season sleeping bag into a four-season sleeping system on the other."
  • RESPONSIBLE DOWN STANDARD (RDS)

    "100% of the down used in our sleeping bags and quilts is independently certified according to the Responsible Down Standard (RDS). The RDS certifies down according to animal welfare requirements and tracks it from source to end product. Purchasing RDS certified products demonstrates the demand for better animal welfare practices in the down and feather supply chain."
  • "Without PFAS"

    "Sea to Summit sleeping bag fabric and insulation are made without PFAS compounds. The PFAS-free DWR coating on the outer shell prevents the insulation from becoming damp if the sleeping bag comes into contact with moisture, e.g. through condensation on the tent wall. Ultra-Dry Down is a PFAS-free hydrophobic treatment that absorbs less moisture and dries faster. It does not affect the breathability or lifespan of the down and lasts for at least 20 weeks. The down used in our sleeping bags comes from responsible sources."
  • FREE FLOW ZIP

    "Our Free Flow construction with three zippers ensures that your sleeping bag offers maximum warmth and efficiency or a variety of ventilation options, depending on your needs."
