Description

The Spark -9C/15F Down is a 3-season sleeping bag for women from the brand Sea to Summit.

With its streamlined mummy shape, high-quality Responsible Down Standard certified goose down with a fill power of 850 CUIN, this model will accompany you on your nights from early spring to late autumn. The down benefits from the Ultra Dry Down water-repellent treatment, providing excellent resistance to water and humidity. The 10D recycled nylon construction prevents condensation forming on the outer shell for increased comfort.

The shape of this sleeping bag is designed to fit your body shape. The hood is ergonomic and adjustable. This model will protect you from the cold down to -1 °C. Very compact, it can easily be slipped into your hiking backpack. Specially designed for women, this model offers better heat retention and features a cut that fits the female morphology. This sleeping bag is an essential companion for your hikes and bivouacs from early spring to late autumn!

The Spark Women's -9C/15F Down sleeping bag from Sea To Summit is a women's sleeping bag, ideal for adventurous women who value comfort.

This season, the Spark has been reworked to fit you better, with a resized hood and improved zips.

Ultra-light
, the Spark has an exceptional weight-to-heat ratio, with a 850+ loft. Compact and stripped down to the bare essentials, it's the minimalist bag for long-distance treks and for those looking for a high-performance bag that won't weigh them down!

Designed in a sarcophagus shape to retain maximum warmth, it is also made up of RDS 850+ down and a Ultra-Dry™ treatment for better insulation and compressibility. It therefore provides good water resistance in wet conditions. With its lightweight 10D nylon structure, it offers excellent breathability and effective temperature regulation.

For even greater comfort, the model has sewn-in structures in the vertical padding at the torso, which optimise the position of the down to prevent it from shifting during use. This bag has a three-quarter length zip and a sealed zip to prevent heat loss.

So the Spark Women's -9C/15F Down bag is a high-performance, lightweight and technical sleeping bag!

Responsible Down Standard (RDS) 100% of the down used in our sleeping bags and duvets is independently certified according to the RDS (Responsible Down Standard). The RDS certifies animal welfare requirements and traceability from source to final product. Purchasing RDS-certified products demonstrates demand for better animal welfare practices in the down and feather supply chain. Sea to Summit is RDS certified.
850+ loft Ultra-Dry Down 850+ Fill Power means that one ounce (30g) of down will re-expand to over 850 cubic inches after compression. A higher loft means less down can be used to achieve the same temperature rating, which is important for high-performance sleeping bags. The loft and quality/composition of the down are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is provided with every Sea to Summit sleeping bag. The down is responsibly sourced, RDS certified, and treated with our PFC-free Ultra-Dry Down™ treatment.
Women's Specific Shape Our women-specific sleeping bags feature a distinctive shape designed to provide greater comfort and optimal thermal efficiency. The models are perfectly tailored to the female body shape, being slightly narrower at the shoulders and roomier at the hips. The down distribution is perfectly adjusted so that the torso and feet stay well insulated.
Quilt Lock System The QuiltLock system uses snaps located at the shoulders and feet of Sea to Summit sleeping bags, along with quilt / footbox straps to attach a quilt to the sleeping bag. This adds thermal performance and versatility to your sleep system: your integrated quilt now works for ultralight summer adventures and transforms your three-season bag into a four-season sleep system.
