With its streamlined mummy shape, high-quality
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 7 °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 late spring to early autumn!
The Spark Women's 7C/45F 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 7C/45F Down bag is a high-performance, lightweight and technical sleeping bag!
