The Spark SpIII sleeping bag from Sea to Summit is a sleeping bag for extreme temperatures.
It is one of the best mountain bags of the brand. Within the Spark range, this bag has a temperature limit of -8ºC. If you plan to sleep in temperatures around -8ºC the Spark SpIII is a good choice.
The Spark SpIII sleeping bag has the best quality padding, a +850 feather, to which they have introduced the water repellent Ultra-Dry Down™. Thanks to this treatment, the humidity that the natural feather can accumulate is eliminated, since the feather is a very good insulator, but it does not repel humidity. It also protects from external moisture and condensation inside the sleeping bag. For your comfort, this bag is made of goose down. The filling is of the best quality, +850 goose down.
The good performance of these mountain mummy bags is based on a combination of excellent materials designed for your comfort, durability and optimization of weight and space. Additionally, the contoured mummy shape and vertical chest panels help prevent heat loss and allow us to provide efficient insulation. Add a hood to protect your head.
One of the lightest and most compact sleeping bags for high mountains.
To optimize weight as well as durability, this bag is made with ultralight finishes like 10D Nylon and a 7D lining. Because we know that every gram of weight matters, we want to make it as light as possible. This model does not weigh 750 grams, depending on its size; smaller or larger, based on your body measurements. Its fill weight also depends on the size.
The SparkIII compresses down to a size so small it will fit in the palm of your hand.
Like the rest of the range, it comes with a light storage and compression bag so you can squeeze the air out of it when you fold it to make it even smaller. The complete zipper of this bag is of high quality, from the YKK brand, the world's largest manufacturer of zippers synonymous with quality and reliability.
