As an authentic XC, the glider was designed to challenge and bring out the adventurer in you. Enjoy maximum performance in each flight. Be in charge by fully and precisely controlling a superb wing able to carry you to the four corners of the world.

Fly hundreds of kilometers under a fast two liner, stable at any speed, and designed for long routes. Easy to manage and understand, with an excellent sink rate or climb in thermals. Maximum performance for experienced pilots, but with an accessibility level never seen in its category.

Through its veins runs the DNA of a world champion, the Icepeak 6, and equipped with the best features and latest technological innovations found with today’s gliders.

Nitinol, to name one, is part of its internal structure, giving a uniform profile design to the wing while keeping the initial performance level intact but reducing the overall weight.

From the glider turning dreams to reality, the Peak 4 was then born. Intense, exciting, built for adventure, and with an insatiable appetite for kilometers, it has an enormous potential for endless exploration anywhere on the planet. Peak 4, the Cross Country spirited wing.

3D Leading Edge

Adding an extra seam to the leading edge on the span axis of the glider helps to shape a compact 3D profile and have better connections to the new 3DP front panel’s layout.

3D Pattern Cut Optimization

The latest glider generation requires a new pattern design and an optimized fabric cutting process based on a 3D technology.

Drag Reduction Structure

With the Drag reduction Structure technology, the trailing edge has been reinforced with small ribs that that makes this part of the glider flatter in order to spread the pressure out evenly. It means better air-flow and less drag on this important part of the glider.

RAM Air Intake

Evolution and constant improving in all our products is the essence of the DNA of Niviuk’s R&D team. Thanks to the new technologies created over recent years, we have conceived new and more evolved and higher performing gliders. In this context the RAM Air Intake technology should be pointed out.

Structured Leading Edge

The SLE provides more rigidity and stability along the span of leading edge but also allows full flexibility along the both the vertical and horizontal axis of each open cell. The SLE ensures ease of movement on the ground and high security in the air during turbulence and whilst flying at speed.

Structured Trailing Edge

The STE optimises the profile without deforming it. We can thus obtain less resistance and better performance.

Titanium Technology-

Constantly innovating, we always are on the hunt, looking for the latest and best materials to helps us design optimal products. For this reason, and after an extensive evaluation of its benefits and qualities, we decided to be the firsts manufacturer to use Nitinol in our glider line.
