FOILSLEEVE™ is a surf brand based in Auckland, New Zealand that has been making accessories for foiling addicts since way back in 2020.

Foil masts from the best manufacturers in the world like gofoil are amazing bits of kit. And, depending on the conditions, you might need a variety of different mast lengths: a shorter mast for learning or for shallow beach or reef breaks; a longer one for choppy surface conditions, for downwinders, or to give you more range for pumping. But high-quality carbon masts are expensive - so it's uncool that you have to buy a whole new mast just to add a few more inches to the top. And that’s why we made FOILSLEEVE™: a simple and cost-effective way to extend the mast you have. 



Those pesky T-Nuts! Always moving, and getting lost. GrabNutz are the world's best stainless steel T-Nuts that lock to your foil tracks - so your foil is always in the right place, and you never lose 'em! #Simples. Remember: before you foil, Grab Yo Nutz!



We manufacture in NZ and sell direct to customers, shipping to anywhere in the world. We do not mark up shipping costs - we try hard to keep the shipping costs as low as possible, but COVID-19 has definitely made it more expensive. If you want to buy multiple units of any product, please contact hello@FOILSLEEVE.com so we'll work out the best shipping option for you. 

COVID UPDATE: Unfortunately, 12 months on, we are still experiencing shipping delays to all destinations due to COVID-19. The lack of aircraft and containers moving around the globe means there are restrictions to freight. Not much we can do - just wear ya mask and stay frosty.





New Zealand might only be a small country at the end of the earth, but we are stacked full of great sailors, surfers, designers and engineers who love the water. Three awesome kiwi companies have helped bring the FOILSLEEVE™ product to life: David of Kinetic Simulation for the 3D design modelling, Gregor at Haeberlin Composites for the engineering and Neil at Creative CNC Solutions for the manufacturing. It's been great fun working together on this.



Each FOILSLEEVE™ is custom made in New Zealand, CNC machined on a 5-axis machine from a single billet of T6 6061 aluminium. The 'skeletor' design is a powerful reflection of the function and is very simple, strong and light. Each unit is then anodised for a high-quality, durable finish. You simply won't break it. 



FOILSLEEVE™ has been modelled on the gofoil tuttle mast. It will also fit other surf and SUP masts, but some tuttles are different. Check out this page for compatibility.

Fitting your FOILSLEEVE™ is a piece of cake: simply slip it onto the top of your existing tuttle mast top, and bolt it either onto your board or onto your plate adaptor using the SleeveBolts supplied. Watch this



As the FOILSLEEVE™ is attached to the top of the foil mast, closest to the board, it has a limited effect on the dynamics of the foil in the water. Some customers notice a little additional drag when the sleeve comes out of the water, but once flying it has no effect. And, as it's light, it makes no noticeable difference to the feel of your foil in flight. True, the sleeve is stiff and does not flex like the carbon mast itself, but we don’t believe this makes any noticeable difference to the overall performance of your foil.



Each FOILSLEEVE™ is built tough. The FOILSLEEVE™ should not fail during normal use, and the warranty covers you against any manufacturing defects and for fair use of the product. The warranty does not, however, cover loss or damage to you and/or any of your equipment if you get smashed in the surf or drilled in high winds. No equipment has a warranty for that. If you get whipped, stuff’s going to break – chances are the FOILSLEEVE™ will be the least of your problems. Be careful out there.

Our GrabNuts™ are made of 316 stainless steel and are bulletproof. All GrabNuts™ are guaranteed for 12 months and our warranty covers you against any manufacturing defects and for fair use of the product.
