The sea to summit spark sp i sleeping bag is light enough that it might just weigh less than your favourite down jacket.
Sea to summit spark spii down sleeping bag review.
The spark ii bag features vertical box baffles on the chest area to minimise movement of down optimising insulation where you need it most with.
The spark spii combines ultra dry down 850 loft premium goose down light gauge 3 ykk zip high performance 10d nylon shell and 7d lining fabrics and a contoured mummy shape for efficient insulation and superior performance.
We tested and assessed the 40 f version for this review.
The first thing we noticed was how light this thing is.
Sea to summit s spark spii down sleeping bag is a true minimalist bag that uses the lightest materials and highest quality responsibly sourced down to deliver an exceptionally high warmth to weight ratio when compared to other similarly rated bags.
All of our down is responsibly sourced rds certified and high loft with a permanent water repellent treatment.
There is a lot to like about the sea to summit spark spii 28 its 850 fill power goose down a total weight barely over a pound and an absolutely miniscule packed volume there is also plenty to dislike about the spark ii.
Higher loft means that less down can be used to achieve the same temperature rating important for performance sleeping bags.
The loft and down quality composition are independently tested by the international down and feather laboratory idfl a copy of the certification is supplied with every sea to summit sleeping bag.
The rds is a tool that is going to help shift the entire down and feather industry towards more humane animal rearing and handling practices.
The outer fabric is water resistant for protection from morning dew and rainfall.
