aker "ISUKA" specialized in a sleeping bag for the mountain climbing
The down Schlafsack Air series that kept three beats that is light, and is small, and is warm
450X is the model that the applied range is the widest to be equivalent to the winter low mountain in autumn from spring.
I use white goose down of 800 Phil power of the highest quality. I set the height of the box on the chest side rather higher than the back side to utilize limited down effectively and fill down on a step part and the chest side that are sensitive to cold a little too much and am the design that thought about thermal insulation efficiency. Furthermore, the original "3D structure" that is not too wide without being too small sends a comfortable feeling of fitting and the heat retention that there is not of waste.
At the time when the temperature is low, "the draft tube" which I located inside of the work "shoulder warmer" of the scarf and a fastener prevents loss of the heat radiation and the invasion of the chill.
To an outer shell, I have super water-repellent performance with a few drops of the performance for a long term and I tear it up and strength, wear resistance are heat-resistant and use superior durable "nylon 66" and are setting to have you use it habitually much more comfortably.
Be superior to the durability at light weight, and the storage bag of the silicon material of two phases of structure that it is easy to receive is attached.
