The Golden4 is the first Gradient glider where we have used Everlast, a double-coated
Porcher material. Everlast was developed by Gradient in co-operation with Porcher Sport,
and this exclusive material provides gliders with long-term stability and durability.
Inside, the inner working of the profile is a result of Gradient’s sports class glider development.
Using the latest software means the tension of the profile could be increased without
compromise. These improvements have allowed the Gradient team to tune the whole wing
without compromising safety.
Small, simple details make this glider complete. Gradient has paid attention to details too,
including: new low-drag micro attachment points on the wing tips; clearing holes on the wing
tips; split A-risers with special karabiners; and a new rucksack, inner bag and riser bag.
