Rebellious, fun, and enlightening, the PUNK tells you the truth about the air. Stay informed, make your own choices, fly the PUNK.
We are on a mission to put taste, control, and attitude back into gliders. The PUNK is a modern-day rebellion towards bland, tasteless paragliders. This new-age wing is an explosion of feel, controllability, and fun. It is a matter of respect. The PUNK will speak the cold hard truth about the conditions, giving you eyes wide-open safety and performance.
End propaganda. Become enlightened. Make your own choices. Fly the uncensored PUNK.
We are all punks. their subculture has shocked the established order and constraints of society. We break the rules of nature, disregard the norms, and have a hell of a time doing it. The High-B PUNK was designed to sink deep into that rebellious part of their brain and enlighten you of reality. Are you a pilot that wants to know the truth?The PUNK will expose it.
BGD has added a 'big ears' A riser which is also on a ½ ratio with the rest of the A lines. This facilitates easy use of big ears while helping speed and stability while on bar. The speed system is light and simple without reflex really helping glide at speed.
OPTIMIZED LINE LAYOUT
Over the years BGD has perfected their system of optimising the line layout of their wings. We use numerous equations, software, and the plain old guess-and-check method to build their line layouts. The result is simple: fewer lines making stronger, faster gliders.
MAXIMISED UNSUPPORTED CELLS
Optimised unsupported cell groups are designed to match the span-wise load distribution influenced by the line layout. Coupled with a strong internal structure, the line layouts that create more span-wise tension can support more unsupported cells. While maintaining a homogenous wing, this helps to minimise line consumption reducing drag thus improving performance.
BDG has maintained the strength and rigidity of the ribs while removing unnecessary material. This means less weight for no increase in cost or reduction in strength of the wing. The hole positioning and size depends on the loads taken locally by the sail, and it is thanks to recent developments in their software that it is now possible to accurately calculate this.
STRONG SHARK NOSE
An ultra-aggressive shark nose optimises stability at all speeds. Not all sharks are created equal and BGD’s shark noses are very aggressive, maximising the effects of the technology.
TRIPLE FINGER DIAGONALS
Across the whole chord of the profile, BGD has designed three-piece diagonal supports that pass through the holes in other ribs. They ensure structural integrity by avoiding cloth bias from the ribs and creating a more solid wing even when brake is applied. This is particularly important near the trailing edge since the profile is thin and the diagonal ribs are shallow supporting higher loads.
CORD CUT BILLOW (CCB)
Cord Cut Billow technology has been developed to improve the form friction, glider stability and overall performance of their paragliders. Two seams run chord-wise across the top panels of the leading edge to accommodate the panel ballooning that happens when the wing is inflated. Up to five centimetres of excess material is created on the sides of an inflated flat panel bending over a wing profile. Cord Cut Billow technology absorbs the material with a 3D panel resulting in fewer ripples and improved rib profile shape and stability.
BGD has added a Post-C band running along the top surface which seamlessly moves down to the bottom surface at the tip, connecting directly to the last line cascade. Instead of putting heavy plastic rods above the C lines BGD use this band to counter the common flip-up ripple caused when applying a little brake. The problem with paragliders is when a little brake is applied the cupping of the trailing edge creates lift which often buckles the profile near the Cs. BGD has solved this problem with the Post-C Band, an eloquent, lightweight, clean and volume reducing solution.
Progressive stability has been designed into all their gliders to help pilots feel turbulence and avoid it. This makes for safer and more comfortable flying.
EYES WIDE-OPEN SAFETY
Gliders that talk are safer. Safer gliders make pilots perform better. Better performing pilots fly further. Further flying pilots are happier pilots. Eyes Wide-open Safety produces happier pilots.

Controllable performance is what I call it. In the PUNK, I have added an extra level of control. Using our trademark “Bruce Goldsmith Handling” and “power steering” there is a kind of inner harmony in the glider that reacts better to pilot inputs.
“When I step off the launch with the PUNK overhead I feel comfortable and in-intimidated. The speed and performance is easier to control and understand.”
The PUNK passed certification tests very easily, and even flown above the top of the weight range, glider safety is not affected. We have decided to extend the certified weight ranges in four sizes of this wing, so you can load it up and still be within certification. The ideal weight ranges are shown in the Specs table.
The extended certified ranges, available on four sizes of Punk, are XS=50-70, S=60-95, M=75-100, ML=88-113.
Extended weight ranges are there for insurance reasons. They enable pilots to fly above the ideal weight range and still fly insured. They should not be considered at all when choosing your correct glider size.
