The SPARK SPIII REGULAR sleeping bag from SEA TO SUMMIT is ultra-light and highly technical. Designed to keep you as warm as possible while optimizing weight and size when packed.
It's versatile so 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 weather conditions.
