DESCRIPTION
The Astro is engineered to deliver top-tier performance across the widest range of wing foil conditions.
From flatwater cruising and effortless transitions, swell rides and surf glides, all the way to the most radical airs and rotations – the Astro was born from and for these moments and this is where it truly thrives.
Performance and comfort, the same criteria, matter for professionals and beginners alike. As a beginner rider, the all new Astro is your all around go to. Getting you on the water for your first forays it makes progression effortless and will be with you through early transitions into seamless ones. As an intermediate rider, when you’re ready to step up to the next level and push harder, the Astro will be right there; taking you from flatwater adventures, into the swells to carve, ride and glide with joy. As an advanced rider, come time you have matured into busting out big airs, you will be right at home on the Astro. As a professional rider you will take its outstanding performance for granted, but truly appreciate the Astro’s comfort, letting you focus on execution of style and the reading of the elements.
Jason Diffin: “Some of the key components I consider when developing Performance and Comfort into our wings are:
Outline Aspect Ratio – The Astro is the result of finding a well balanced wingspan to strut length ratio for good power and good clearance of the wing tips from the water.
Overall Stiffness – The inflated LE sectional diameters have been tweaked and tuned to find the perfect diameter to support canopy and provide the required stiffness to support the wing frame.
Profile Depth and Placement – A radial load line layout provides an enhanced dynamic feel and stability.
Dynamic Twist – Frame stiffness and seam shaping combine to keep the canopy draft locked in the right place to create the proper twist and release on the trailing edge of the wing.”

CONSTRUCTION
Wing Designer Jason Diffin: “I have taken my deep roots in super light windsurf sail design and transferred that knowledge over to the wing design. This background has given me a unique understanding and perspective in approaching the wing design. I have focused some high end design improvements in areas I consider to be key to the end result. The LE and Strut material is ultra low stretch and reinforced rip stop Dacron which provides a perfect blend of stiffness, durability, flex and profile stabilization. Canopy Radial Load Line Layout for enhanced dynamic feel and stability. Chafe protection on the tips and tail prevent premature wear and tear during rigging and maneuvering on land. Reinforced seams have been put into chafe prone areas to ensure longer life and durability.

BOOM
The all new KT Foiling Seamless Boom System. A super lightweight, custom profiled boom. Providing a light and stiff feel and distinctive directional awareness in the hands. A continuous boom provides the most direct and unrestricted connection to your wing. Meaning you can push or pull from any point on the boom and the response is immediate. Sizes 3.5 and above come with a carbon boom. Sizes 3.0 and below come with an aluminum boom.

HANDLE
In addition to the boom, there is a Leading Edge surf handle. The placement has been tuned and defined to identify the perfect balance point allowing the wing to fly beautifully in neutral whilst swooping, gliding and surfing on foil.

VALVES
Simple lightweight B2 valves require no special nozzle, are easily serviced and most importantly feather light.

VISIBILITY
Trademark KT Foiling bright fluo color options prioritize visual impact, visibility and safety. Our fluorescent materials are the most recognizable colorways on the water. An important detail, when you are trying to spot a rider – loved one or offspring – from far away.
