Sea to Summit Spark Sp0 Sleeping Bag (Regular)
The Sea to Summit Spark™ Series is what you reach for when you need a high performance sleeping bag without the weight. The Spark™ Series spans everything from an ultralight liner to an expedition weight mid-winter bag. While the end usage is very different, they reflect a design ethos of matching weather conditions to the lightest bag possible. The Spark Sp0 is an ultralight liner, ideal for ultra trail runners, summer hiking and camping or as a liner for inside a heavier, warmer bag. This sleeping bag features a contoured mummy shape and is made from premium goose down for efficient insulation. Ultra-light and technical, the Spark™ Series bags are designed to keep you as warm as possible while minimising packed weight and size.
Spark Sleeping Bag Features:
- Contoured mummy shape for efficient insulation
- Ideal for mid-summer fast hikes or adventure racing
- Doubles as a liner to significantly boost the warmth of a second bag
- Extremely lightweight and compact
- Water repellent polymer treatment applied
- RDS Certified Down
The EN13537 is a European standard for sleeping bags that provides three temperature levels to help guide you when choosing a bag.
850+ Fill Power indicates that 1 oz of down will re-expand to over 850 cubic inches after compression. Higher loft means that less down can be used to achieve the same temperature rating – important for performance sleeping bags. The loft and down quality/composition are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is supplied with every Sea to Summit sleeping bag.
ULTRA-DRY Down™ is a permanent nano-level water repellent polymer treatment applied to our down which protects it from external moisture and condensation from inside the bag virtually eliminating the negative effects moisture has on down.
