Sea to Summit Spark Down Sleeping Bag 7C - Regular Beluga

Product Description

The Spark 7C is designed for those who count every gram but still demand high-level performance. Whether you are trekking through high-altitude terrain or embarking on a long-distance cycling tour, this ultralight gear ensures you stay agile. The minimalist design is focused on efficiency, allowing you to pack more into your days and carry less on your back. The mummy shape is tailored to follow the contours of your body, ensuring that heat is trapped close to you, while the ergonomic hood can be adjusted to seal in warmth during cooler spells. It is the perfect choice for high-intensity trips where mobility and restful sleep are equally important. The core of this sleeping bag is the premium 850+ Loft goose down, which provides exceptional insulation for its weight. To ensure performance in humid conditions, the down is treated with an Ultra-Dry Down finish, which prevents the feathers from clumping when exposed to moisture. This means the bag retains its loft and warmth even in damp environments or when condensation builds up inside your shelter. The shell and lining are constructed from a 10-denier nylon fabric, which is incredibly light and highly breathable, helping to regulate your body temperature throughout the night. Technical precision is further enhanced by the sewn-through baffle construction, which keeps the weight at an absolute minimum for summer and warm-climate use. The half-length YKK zipper is equipped with a snag-free plow, ensuring smooth operation every time you get in or out. The 10D shell also features a PFC-free DWR treatment, which sheds light moisture and wind. This combination of high-end materials and thoughtful engineering results in a pack volume of just 2 liters, making it one of the most compact sleeping systems available for outdoor enthusiasts.
