1000 3D Ultralight is a warm down sleeping bag designed for winter backpacking and mountaineering.
The insulation is hydrophobic 870+ Fill Power goose down (confirmed by the IDFL laboratory in Switzerland). The combination of high quality down and thin but durable 10den nylon makes the sleeping bag warm, lightweight and compact at the same time.
The 3D sewing technology provides reliable and even heat retention. It is based on a differential cut. The outer fabric of the sleeping bag is larger than the inner fabric. This design minimises the risk of cold spots in areas where tension can build up, such as the shoulders or elbows. The tension is generated exclusively on the inner fabric, so the down insulation doesn’t compress, preserves its maximum volume and continues to retain heat inside the sleeping bag.
There is a system of two insulated strips along the zip, which reliably protects against drafts.
The hydrophobic fabric and down impregnation keep the sleeping bag dry and efficient even in high humidity.
