The Spark Sp0 Down Sleeping Bag is a true minimalist bag that uses the lightest materials and highest quality, responsibly sourced  down to deliver an exceptionally high warmth to weight ratio, when compared to other similarly rated bags. Best used in the Summer or as a liner to boost performance of another bag.

The Spark 0 bag features vertical baffles on the chest area to minimise movement of down, optimising insulation where you need it most. The half zip saves weight and reduces heat loss at the expense of venting if conditions are too warm.

The contoured mummy shape isn’t too constrictive and the super thin and light outer fabrics means more care will be needed than with more heavy duty bags. The bag compresses down to a very small size.

The RDS 850+ Loft premium goose down, light-gauge #3 YKK zip and high performance 10D Nylon shell and 7D lining fabrics, set the stage for a superior performance along with there Ultra-Dry Down water-repellent treatment that protects the down from external moisture and condensation from the inside of the bag, virtually eliminating the negative effects moisture has on down. All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down. The Ultra-Dry Down protection also makes the Spark an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.

Description

    • 850+ Loft: 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™ 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.
