A unique take on a traditional carving ski — take it anywhere. Easy to ski, yet has no top end.


The Z-90 really is a unique ski and fits in-between categories that most people think of. It has the shape of a traditional carver with a 15m radius, yet at 90mm underfoot, its wide enough to duck off trails, power through crust & crud and even surf powder. It’s easy to ski casually but rips when you lay it over — there’s no top end.


Waist:90mm waist


Radius:16m (180cm), 15m (174cm), 14m (165cm), 14m (157cm)

Lengths:191, 184, 178, 169, 160cm

Weight:1,950g/ski (180cm), 1,900g/ski (174cm), 1,850g/ski (165cm), 1,775g/ski (157cm)


Technology:8 inlays of HDT™ (13-15% core volume)

Core: Canadian Maple with HDT™ inlays

Reinforcement: Two full sheets of Titinal metal, carbon fiber and tri-axial fiberglass

  • 90mm waist
    We combined a traditional carver shape and wider waist to make a super capable all-around ski that rips on groomers.
  • Non-Newtonian
    We embed channels of a non-newtonian polymer that literally adapts to snow conditions and ski style. When exposed to higher speeds and vibrations, the polymer hardens actively damping the ski. It sounds too good to be true, right?


We embed channels of a non-newtonian polymer called HDT™ into every ski we make. When exposed to vibrations, the polymer hardens actively damping the ski. It literally adapts to snow conditions and ski style. It’s the first of its kind, sounds too good to be true, right?!

Best skis and incredible service

These skis are incredible. The z-77’s are unbelievably light, stable and quiet yet not overly stiff. After skiing them for a few days I ordered a pair of the endurance too. The customer service is equally incredible. Quick to answer any questions and very quick getting me the skis. My friends probably think I’m on commission I’ve been talking the up so much.

They live up to the hype

I now have about 15 days on my new Z Line skis and they have significantly exceeded my expectations. They are the perfect New England ski. They are great carvers on groomers, holding a line , whether -quick turns along the side of a trail, or wide turns, without sliding as the trail is skied off in the afternoon. It is easy to get them around on the bumps, and they really excel in holding an edge on the bullet proof bumps we encounter after a thaw/ rain/ freeze cycle. They are versatile, skiing equally well in the woods and groomed and ungroomed terrain. They are a pleasure to ski.

First turn was amazing....but it kept getting better!

The Z-90 is the best, most versatile, and most fun ski I have ever skied. Clean carves, energy from turn to turn, easy to vary turn shape, handles all conditions from AM soft snow to icy patches to afternoon crud. The HDT really works....ski them faster and feel the damping effect; ski them slowly and the ski turns easily with a big sweet spot. So much fun!!! The Z-90 has made my other skis obsolete.......now I just want to try an Endurance or Citadel!


Z-90 in 90mm, 180cm Great Ski

Very impressive and the HDT does work. The most interesting is the fact the faster you go the more stable it gets. Just laughed going down the hill at how stable it gets the harder you push it. Never had a ski like this in the 35 years + of skiing. Short to long carves, does it all. Well done, ordering the Citadel to replace my aging Soul 7's.

174 Z-line

Skied my new 174 Z line Renouns this weekend. Loved them, and I can't say that about a ski very often! Typically, if it hasn't been a volkl o a stockli, I'll ski a new ski once and either sell them or give them to a friend. I'm keeping these bad boys - super playful and can arc a turn on super firm snow! Smiled all day! Glad I found you guys! John

Proud to be part of the RENOUN family

After using borrowed equipment for much of the winter, I screwed up my courage and bought the Z90s and a pair arrived a few weeks ago. I have been able to use them and oh - what a difference. They are not skis they are rockets, and the more you drive into them the more they deliver for you. In the past several weeks there has been everything from solid ice to frozen granular and powder and wet mashed potatoes and these Renoun  skis have handled all of it. But the most remarkable time was two weeks ago on solid white ice -  in which case of the carving characteristics were absolutely stunning. The combination of the smoothness of the anti-vibration and the ski cut slices across ice with complete control and stability at whatever speed you want to go with. In the softer stuff there’s wonderful float and maneuverability through bumps, taking me through terrain  that I would never have taken on myself. I try to keep up with a pretty fast crowd at wildcat and they are exceptional skiers – it was an amazing moment after a few runs on the new Z90s - one of those great skiers leaned over to me on the chairlift and said “I don’t know what’s in those skis Bob but you’re skiing has been transformed- You have confidence and speed. We’re all really proud of you”. Thank you so much.  I am proud to be part of this family of the Renoun skis that you have created.

What you invented is a miracle

I didn’t believe what you were promising :))) Gentlemen, CONGRATULATIONS. My first day out was incredible. Worst conditions ever : heavy wet snow, not groomed. Your equipment made it possible. TY I want a lilifetime discount starting with my second pair :))) I am dead serious. What you did/ invented/ developed is a miracle. I am 49 110 kg . Today was foggy, +6", wet tough snow and there was not even one groomed track. People just don t ski at the end of March in Romania because you usually don t have snow at this time of the year. I was having second thoughts even trying. But i did. I am amazed. I had a wonderful time because it was easy. You have a fan at the other side of the world. Sincerely, Adrian from Romania

Better than the Volkl XTM's!

I had a pair of Volkl XTM’s and these are so much better in so many ways. They really are stable and stiff on hard packed groomers, and light and flexible in bumps and powder. We had a fair bit of powder in Whistler so I really put them to the test and they performed really, really well. Thanks again!


Truly amazed

I am truly amazed. I have had them in 10” of snow to full on ice and everything in between, icy hard packed w/granular on top. I have tried to find ‘some surface’ that they don’t behave.. HAS NOT HAPPENED I love them!!! They are the elusive 1 ski quiver.


Super responsive, super stable, virtually no chatter on the ice!

I bought a pair of Z90’s in late November and finally got to ski on them this past Friday. When I bought them I thought, “Hey, these sound cool and I’ll get to support a fellow Clarkson alum with his new business. Worst case scenario, they’ll be just like regular skis and I’ll at least have a new pair that will do better in powdery conditions than my current Rossis.” Man, was I surprised. They were freakin’ great. I skied Winter Park, CO with a buddy of mine, and the conditions were all over the place. Powder, crud, crusty snow, a bit of ice here and there, etc. The Z90’s were solid up and down the mountain — super responsive, super stable, virtually no chatter on the crusty stuff. It was my first day of the season and I looked like a pro instead of some schmo on his first day with new gear. Verdict: I love them, they’re the best skis I’ve ever had.

Favorite skis to ride front side

I have been riding these skis the last 3 seasons. Before I had these skis I would use my touring set up on the front side...well f that noise. These are most stable and playful skis I have ever been on. Imagine ripping down the mountain, groomers, ice, chop and never finding a speed that was too fast - that is what riding these is like. Endless fun. It's easy to get lost in clever marketing and top sheets but these skis are the real deal. I can't imagine having a more fun ski than these.

Hands down the best I have Skied.

First the customer service and time Cyrus and company have given has been awesome. Ordering online can be kinda of scary but they make it so easy and answered every question I had. I am a heavy dude( 265lbs ) , over the last several years of skiing had real sorness each day after a day on the moutain. The only thing that I changed this year was the Ski's. Not an expert by any means but , the z90's went where I wanted them to go and did what I wanted them to do. Mostly skiied Groomers and some hard pack , nothing Fresh in Colo over xmas, they really held that edge . But what was there was great and The z90's handled everything I could throw at them. They did not feel heavy or like prior skis I have used , I am using Look Pivot 14 on them and they balance nicely . I cant wait to ski these again next month-

They make me a better skier

While the skis do not make me taller, younger or better looking (according to my wife) they do make me a much better skier. I LOVE them. They hold on ice and hard pack better and turn more easily than any ski I have ever tried. And they are just plain FUN. Thank you.


Exceeds my expectation

Cyrus, I've been waiting to get more time in various conditions before responding. Looks like I will get them in about a foot of new this weekend. I've skied them at Copper, Winter Park, and Mary Jane. WOW am I happy. Seriously happy. I posted a pic on Epic were I skied on icy hard pack with about 1/2" of snow on top. I couldn't believe they held so well. A 90mm ski. They were amazing. They are exceeding my expectations as an all mountain front side biased ski. For me, they kill in 5"-7" of crud/chop. Groomed? Leaves me smiling ear to ear. Easy to get on edge. Smooth in various turn radius. Thank you Cyrus! I could go on and on but you get the idea. I'm an extremely happy customer.


Something magical

My husband bought a pair of Z-90's in March and absolutely loves them. He actually completely exhausted himself the first day that he got on them because he was having way too much fun with g-forces. He said the difference in feel between the Z-90 and his Kästle FX 84's was not even close. And I could notice the difference in his skiing. You've created something magical. He's now selling the Kästles. :-)


Like Nothing I've Ever Skied Before

I demoed a pair at Stratton on a day that was perfect to judge these skis. There were piles of loose powder, sheets of ice and some carvable soft snow mixed in. The response from these things was incredible. Just at the second you expect chatter, they smooth out. When pushed for some serious speed, they were super stable. I have not stopped talking about this pair of skis since that day over a month ago. When I meet you on the Stratton gondola, you'll know it's me when I bend your ear about that time I demoed the Renoun skis.
