DRILITE ® Loft 30 D – resistant to water and wind
DRILITE ® Loft 30 D is a strong and light waterproof surface material with PU coating. It is highly breathable and resistant to water and wind.

The feathers are thus protected from moisture, thus also from losing their heat-insulating properties. Thanks to its water resistance and low weight, the feathers maintain a high loft for maximum thermal insulation in any conditions.- Light material - 55 g/m 2.
- Highly breathable.
- Wind resistant.

The best goose down on the market - 800+ fill

This destroys the mites and the environment for their life, which is especially appreciated by allergy sufferers. The feathers retain their important fatness and loft, are easily packable, have high insulation and low weight.

300 g of the highest quality goose feathers 800 cuin
- Each chamber and its shape is precisely designed for its purpose and maximum insulation. In addition , the exact amount of feathers, which are filled into each chamber separately, is calculated per gram. K7 JACKET is filled with the highest quality goose down 90/10 with a filling of 800 cuin. In total, the jacket contains 300 g, which is enough to provide excellent thermal comfort in really extreme conditions.
3D chambers without cold seams
- Most lower end down jackets have the seams between the chambers stitched through. Sú to tzv. studené švy. Heat then escapes more easily through them. With the K7 JACKET, this problem is solved with the help of 3D chambers, which reduce heat leakage to the all-important minimum.
Really warm hood - Full Dome HC Hood + EXL
- Fully adjustable hood, compatible with a helmet and protected from the inside by a waterproof DRILITE ® Loft membrane. The feathers stay dry even if snow falls into your hood. Most heat escapes through the head, so it must be perfectly protected. That's why this hood, used mainly for expedition down jackets, has 3D chambers, which prevents heat from escaping through the seams. A high collar and stretch seams on the inside of the hood were also designed for this, which help to wrap the head perfectly and do not let any heat escape. The drawstrings of the hood are sewn into the channels so that they don't bother you in the wind.
- The jacket has a longer cut and the last chamber has a special shape that closes the space around the waist and minimizes heat loss. The lower hem can still be pulled down with the help of ingenious laces, the use of which is really intuitive.
