Are you someone who counts every gram, yet still values a good night's sleep? Then the Sea to Summit Spark sleeping bag is exactly what you're looking for. This ultralight down sleeping bag offers maximum warmth with minimal weight – ideal for hikers, bikepackers, and adventurers who want to travel efficiently.
The filling consists of RDS-certified goose down with a fill power of 850+ and is treated with Ultra-Dry Down™ , a PFC-free water-repellent treatment that keeps the down dry and lofty, even in damp conditions. This ensures optimal insulation performance.
For added warmth, the Spark features a technical hood and a zippered draft flap that keeps cold air out. The super-breathable 10-denier lining feels comfortable against the skin, while the 10D outer shell with a PFC-free DWR coating and additional water-repellent fabric on the hood and foot box protect you from wind and condensation.
The full-length zipper allows the Spark to be paired with a women's model from the Spark series , so couples can enjoy extra comfort and warmth together.
