Overview

Ultra-light and technical, the Spark SPI is designed to keep you as warm as possible for the least weight and size

Updated for 2019, the Spark SPI 5C Sleeping Bag from Sea To Summit combines a superlight but high-loft sustainably sourced down insulation with minimalist fabric construction. This season sees a few key updates to the spark series, including vertical chest baffles that stop down shifting laterally and increase warmth during the night. 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 superior performance. A squarer footbox is designed to keep your toes cosy on colder evenings.

The Spark is an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option.
