Description

Elevate your fast-and-light adventures with the Sea to Summit Spark Sleeping Bag, an engineering marvel designed for the minimalist explorer who demands performance without the weight penalty. This ultralight sleeping bag is the ultimate companion for thru-hiking, bikepacking, and alpine-style ascents where every gram is meticulously counted. Experience the freedom of a smaller, lighter pack, allowing you to move further and faster on the trail.
The Spark sleeping bag redefines what´s possible in the world of lightweight outdoor gear. Its primary benefit lies in its exceptional warmth-to-weight ratio, delivered by high-performance, premium insulated down. This lofty insulation traps body heat with incredible efficiency, ensuring you stay comfortable during cool summer and late spring nights. The bag’s design focuses on thermal performance, featuring a contoured mummy shape that minimizes dead air space and maximizes heat retention, wrapping you in a cocoon of warmth.
Designed as a versatile adult sleeping bag suitable for both men and women, the Spark is packed with features to enhance your comfort in the backcountry. A technical, adjustable hood can be cinched down tightly to prevent precious heat from escaping on colder evenings. The thoughtful construction includes strategic baffling that keeps the down insulation exactly where it needs to be, preventing cold spots and ensuring consistent warmth all night long. A weight-conscious zipper design provides ventilation when needed while shaving critical grams from the overall weight. The ultralight shell material provides a durable yet featherlight barrier, completing a package that is as robust as it is compact.
Whether you´re planning a multi-day trek through the mountains or a quick overnight escape, the Sea to Summit Spark provides the reliable warmth and unparalleled packability you need. It’s the perfect choice for temperatures hovering around its recommended 11 °C, with a lower limit of 7 °C for those cooler-than-expected nights. When your adventure is over, it compresses down to an impressively small size, freeing up valuable space in your pack for other essential gear. Choose the Spark when performance is paramount and a restful night´s sleep is non-negotiable.
