Construction
EE relies on a unique U-shaped chamber construction in its quilts, which combines the best features of traditional horizontal and vertical chambers. Vertical chambers prevent down from shifting to the sides, which most often occurs when sleeping on your side. Horizontal chambers in the foot box maintain maximum loft and keep the down exactly where it's needed.
Between the individual chambers, there are vertical baffles that significantly reduce heat loss at the junction of two chambers compared to simpler sewn through constructions.
To save weight and improve packability, quilts are stripped of all unnecessary features. On its back side from the waist up, inefficiently used down is removed, which would be mostly compressed under your body and practically serve no purpose. To keep the opening on your back underneath you at all times, the quilt is attached to the sleeping pad using elastic straps. The quilt remains in a fixed position, and you can turn inside it. The quilt can be used with any type of sleeping pad (inflatable or foam). Additionally, the quilt does not have a hood; you can replace it with a hat or a hooded down jacket/sweatshirt.
