Spark SpII Regular [ST81233001] | SEA TO SUMMIT

Sea to Summit Spark SpII Regular (sleeping bag)

■Quote from manufacturer's description Spark is a series that pursues lightweight and compactness while providing excellent heat retention.
It can be used as an ultra-light liner, and its light weight makes it ideal for expeditions during harsh winter conditions.
Even if the usage scenario is very different, it firmly reflects the design concept of "being as light as possible while adapting to the climate."
The Spark Sp2 has the same silhouette as the SpI, but is filled with more down in key areas for improved heat retention.
Box-shaped vertical baffles are placed above the torso, allowing more down to be enclosed and improving insulation for the core of the body.
The lower part is a lightweight sewn horizontal baffle.
The half-length zipper has two sliders, allowing for excellent ventilation and ease of use.
In addition, the sizing of the previous model has been revised to provide more room in the shoulders and waist.
Ultra Dry Down is treated with a water-repellent coating to virtually eliminate moisture, which can have a detrimental effect on down.
It protects the down from water vapor in the outside air and prevents condensation inside.
By using Ultra Dry Down, the jacket can be used in harsh environments such as alpine climbing and adventure racing, where a difference of 1g is crucial.
