The SPARK SPI REGULAR sleeping bag from SEA TO SUMMIT is as ultra-light as it is technical. Designed to keep you as warm as possible while optimizing weight and size when packed.
It is so versatile that it can be used in all conditions for winter expeditions. The ULTRA-DRY Down water repellent treatment protects the down from external moisture and condensation inside the sleeping bag, limiting the negative effects of moisture on the down. ULTRA-DRY Down protection also allows the sleeping bag to perform in harsh conditions.
If you're looking for a performance sleeping bag, but don't want to be weighed down by it, the Spark SPI is for you.
