What is the Sea to Summit Women’s Spark -9C Regular Sleeping Bag?
Meet the Sea to Summit Spark -9C Sleeping Bag, meticulously designed with a women's specific fit to provide optimal warmth and comfort. Engineered for chilly conditions, it ensures cosy nights under the stars with added heat retention. It's crafted using premium materials and boasts an optimal warmth-to-weight ratio. This sleeping bag offers lightweight and compact performance, making it the perfect choice for your next expedition.
What is it made of?
Insulation:The insulation of the Sea to Summit Spark sleeping bag is composed of 850+ fill power goose down. This high fill power ensures an exceptional warmth-to-weight ratio, meaning the bag can provide significant warmth without adding excessive weight, making it ideal for backpacking and outdoor adventures where each gram matters.
Additionally, the goose down undergoes Ultra Dry Down treatment, enhancing its water resistance in damp conditions. This treatment ensures that even if the sleeping bag gets exposed to moisture, the down insulation retains its loft and insulating properties, keeping you warm and comfortable throughout the night.
The Responsible Down Standard (RDS) certification guarantees ethical sourcing practices, ensuring that the down is obtained from geese that have been treated humanely. Furthermore, independent testing by the International Down and Feather Laboratory (IDFL) ensures the quality and performance of the down insulation, reassuring users about the insulation's reliability.
This sleeping bag also boasts non-PFC (Perfluorinated Chemicals) status. PFCs are commonly used in outdoor gear to provide water repellency, but they have been linked to environmental and health concerns. By opting for non-PFC materials, Sea to Summit ensures their products are free from these potentially harmful chemicals, promoting environmental responsibility and user safety.
Shell and Lining:The shell and lining of the Sea to Summit Spark sleeping bag are constructed using 10-denier nylon fabric. This material is lightweight, which is advantageous for backpackers and those looking to minimise the weight of their gear without compromising on durability or performance.
The 10-denier nylon fabric offers breathability, allowing moisture vapour to escape from the interior of the sleeping bag, thus preventing overheating and ensuring comfort throughout the night. Moreover, it provides effective temperature regulation, helping to keep you warm in cold conditions while preventing overheating in warmer temperatures.
Hood and Footbox:The hood and footbox of the Sea to Summit Spark sleeping bag feature 10-denier nylon waterproof-breathable fabric. This material offers enhanced protection against moisture, ensuring you stay dry even in damp or wet conditions. The waterproof feature prevents water from seeping into the sleeping bag, while the breathable aspect allows moisture vapour to escape, preventing condensation buildup inside the bag.
What are its features?
The women’s mummy fit of the Sea to Summit Spark sleeping bag ensures optimal comfort by providing ample room at the hips while maintaining a snug fit around the shoulders and torso. This thoughtful design maximises warmth and comfort, allowing you to enjoy restful nights under the stars during your outdoor escapades.
Equipped with a primary zip featuring a 3/4 length #5 zipper, the Spark sleeping bag offers convenient access and ventilation options. The zip includes a zip-plow feature and two sliders, allowing for smooth operation and customisation of ventilation according to the user's preference. Whether you need to quickly regulate temperature or easily enter and exit the sleeping bag, the zip design ensures comfortable and hassle-free use.
The QuiltLock system further enhances the versatility and thermal performance of this Sea to Summit sleeping bag.
By securely attaching a quilt to the sleeping bag using snap locks located at the shoulder and foot end, the QuiltLock system transforms a three-season bag into a four-season solution.
The system provides added insulation and warmth, particularly in colder conditions, ensuring you can stay comfortable and protected from the elements.
This sleeping bag comes in a relaxed mummy fit. This design ensures high thermal efficiency while providing freedom of movement for a more comfortable sleep experience.
The combination of box wall baffles in the top half of the sleeping bag and sewn-through quilted construction in the lower half represents a great approach to insulation and comfort. In the top half, box wall baffles create individual chambers that maintain the loft of the down insulation, ensuring consistent warmth and minimising cold spots. This design is particularly effective in areas where insulation is crucial, such as around the torso and shoulders. Meanwhile, the sewn-through quilted construction in the lower half provides a lightweight and breathable solution, ideal for areas with less critical insulation needs. This thoughtful combination ensures that the sleeping bag offers optimal warmth and comfort throughout, catering to different insulation needs across the body and enhancing the overall sleeping experience in diverse outdoor conditions.
A double draft collar provides extra insulation and protection against cold drafts, ensuring a snug and cosy sleeping environment. Double draft collars enhance thermal efficiency by effectively sealing in body heat and preventing cold air from entering the sleeping bag. They work great in chilly conditions or during cold nights in the wilderness.
The Spark sleeping bag also has a technical hood, which features a soft-touch adjustment for personalised fit and an extra-deep design. It provides a snug and cosy feel and ensures that you can rest peacefully, protected from the elements and be ready to tackle the next day's adventures.
The incorporation of a single, down-filled draft tube along the top of all zippers prevents cold air from seeping through the zipper but also enhances insulation, ensuring optimal warmth retention throughout the night.
