SEA TO SUMMIT Spark Down Sleeping Bag

The Spark sleeping bag series from Sea to Summit is the ideal
solution for anyone looking for ultralight, top-quality products that provide
comfortable and restful sleep.

Spark sleeping bags are filled with 850+ loft goose down sourced from
controlled farms certified to the Responsible Down Standard (RDS). The down
also features a hydrophobic treatment that prevents it from absorbing
moisture, ensuring excellent thermal insulation and outstanding sleeping comfort. The mummy-shaped Spark
is equipped with a technical hood and a thermal draft tube along the
zipper to protect against the loss of valuable heat. The inside of the sleeping bag is made from a pleasant, breathable
material, while the outer layer, like the down, is treated with an
eco-friendly, hydrophobic PFC-free finish. Reinforcements in the hood and
foot areas protect against wind and moisture. Models in the Spark series feature a
full-length zipper, allowing them to be joined with the women’s version – Spark Lady.
