Sea To Summit Spark 3 SPIII Down Sleeping Bag

Sea To Summit Spark 3 SPIII Down Sleeping Bag

 

Designed to maximise warmth and minimise bulk, the Spark Series offers a range of sleeping bags ideal for any climate, from ultralight liner to winter-ready expedition weight bag. All reflecting a philosophy of utilising the lightest bag possible while still providing suitable protection from the elements. Premium RDS 850+ Loft goose down, #3 YKK zip, 10D Nylon shell, and 7D lining fabrics have all been strategically chosen for maximum performance. Through insulative materials and a contoured mummy shape, Sea To Summit provides a snug fit combined with efficient insulation. Every model is modified to optimise it for its intended use. The ULTRA-DRY Down™ treatment has been applied to the down insulation, providing protection from external moisture and mitigating any impacts from internal condensation. All Sea to Summit Down Sleeping Bags use Responsible Down Standard (RDS) certified down. The ULTRADRY Down™ protection also makes the Spark™ an impressive hard-alpine or adventure racing bag, where every gram is counted and down has never been a viable option
