Days Examined:


Renoun makes some fairly wild skis. Their Endurance 98 and Citadel 106 are each extraordinarily mild in comparison with different skis of their respective courses, and Renoun’s “Hyper Damping Technology” (aka, HDT) leads to an on-snow really feel that’s in contrast to something we’ve ever skied earlier than (particularly for skis which are as mild because the Endurance 98 and Citadel 106). For extra on the origin story of Renoun and HDT, take a look at our podcast with Renoun founder, Cyrus Schenck.

However Renoun’s narrower shapes, the Z-Line 77 and Z-Line 90, are a bit totally different than the model’s different fashions. And by that we imply that the Z-Line skis truly look fairly conventional on paper.

So what occurs once you put HDT right into a ski with a extra conventional form and development?

We spent a number of time on the Z-Line 90 this previous season to seek out out precisely that. So whereas we put collectively our full evaluation, have a look under to see the place the Z-Line 90 differs — and doesn’t differ — from the opposite skis in its class.

What Renoun says concerning the Z-Line:

“Distinctive for its innovative design, the Z-Line is your performance carving ski in every condition. A stunning meld of classic architecture and modern technology brings you unparalleled stability and control. In the past, the design of an on-piste ski left it landlocked on groomers. But with HDT™ in the core, we freed it up for any slope: early morning corduroy, trees, bumps and late day crud. With the Z-Line, we’ve engineered a carving ski that hyper connects you, your skis, and the snow. Make nimble transitions and effortless turns with incredible stability no matter what the mountain throws at you. This is skiing like never before.”

A pair issues about this description stand out:

(1) Renoun says the Z-Line 90 melds “classic architecture and modern technology.” And based mostly on the ski’s development and form, that appears fairly correct, although it is dependent upon the way you’re categorizing the Z-Line 90 (see our subsequent two sections).

(2) Renoun claims that the Z-Line 90 isn’t a ski that’s “landlocked on groomers,” however performs properly everywhere in the mountain, and in a greater variety of circumstances than typical carving skis, together with “early morning corduroy, trees, bumps and late day crud.”

And that’s not all they are saying concerning the Z-Line 90’s all-mountain chops: “If you find yourself on groomers slightly more than trees, bumps or pow, then this is your ski.” And, “the 90mm version handles everything on the mountain — trees, bumps, groomers, crud, light powder, you name it.” Lastly, Renoun says that the Z-Line 90 is greatest for many who, “ski the entire mountain, yet love the heart & soul of a carving ski.”

All of that replicate provides as much as a reasonably fascinating description, and a few huge claims. It’s fairly straightforward to make a superb carver. It’s additionally fairly straightforward to construct a 90mm-wide ski that works properly everywhere in the mountain. However we’ve been on few skis that deal with each of this stuff equally nicely. So is the Z-Line 90 actually the exception? That is one thing we’ll undoubtedly be weighing in on.


Renoun has packed plenty of tech into the Z-Line 90. It begins with a maple core, which is a heavier wooden than the Aspen used within the Renoun Endurance 98 and Citadel 106. Then they add each carbon fiber and two sheets of titanal the core of the Z-Line 90. After which Renoun finishes it off with eight of their signature HDT inlays.

Renoun Z-Line 90 — Core Development

All these development parts appear aimed towards offering a humid and secure really feel, which is sensible for a ski that’s supposed to supply “incredible stability no matter what the mountain throws at you.” It additionally signifies that the Z-Line 90 isn’t as extremely (ridiculously?) mild as the opposite skis in Renoun’s lineup (extra on that later).

Form / Rocker Profile

Renoun talks concerning the Z-Line 90’s “classic architecture,” and that’s a superb description, although it does rely a bit on the way you’re excited about and categorizing the Z-Line 90.

The Z-Line 90 seems rather a lot like a wider, conventional carving ski, with very broad ideas and tails, virtually no taper, and plenty of sidecut (16 m for the 180 cm model).

And the “hammerhead” tip form of the Z-Line 90 is a form that often does a fantastic job of pulling you right into a flip and offering strong edgehold.

However once more, Renoun additionally emphasizes the Z-Line 90’s all-mountain efficiency, and we’ve typically discovered that “hammerhead” ideas like these on the Z-Line 90 can really feel cumbersome when snowboarding off-piste in tight moguls, steeper chutes, and so on.

The Z-Line 90 additionally has numerous camber, virtually no tail rocker / tail splay, and a tip that has loads of tip splay however a really shallow tip rocker line.

Flex Sample

Hand flexing the Z-Line 90, right here’s how we’d characterize its flex sample:

Ideas: 7.5-Eight
Shovels: Eight.5-9
In Entrance of Toe Piece: 9-9.5
Underfoot: 9
Behind Heel Piece: 9-Eight.5
Tails: Eight.5-9.5

This can be a fairly robust, strong flex sample, and it’s fairly according to quite a few the skis on this class. The 18/19 HEAD Monster 88 is stiffer all through (it’s nonetheless one of many stiffest ~88 mm skis on the market), however the general variations in flex sample are fairly delicate between the Z-Line 90 and skis just like the HEAD Kore 93, Atomic Vantage 90 Ti, and Volkl Kendo.


At 90 mm underfoot, the Z-Line 90 matches into an fascinating slot — it’s wider than most devoted carvers, and within the ballpark of narrower all-mountain skis. So whereas the Z-Line 90’s form seems like that of a carving ski, its width places it into the identical class as some fairly versatile all-mountain skis just like the Blizzard Brahma, Folsom Spar 88, Volkl Kendo, and DPS Basis Cassiar 94.

And this raises the query: what do you actually achieve or lose by going with a wider ski that has a form that’s just like many narrower, piste-oriented carving skis?


The Renoun Endurance 98 and Citadel 106 are extraordinarily mild in comparison with different skis of their respective courses.

However the Z-Line 90 isn’t as loopy mild as the opposite skis in Renoun’s lineup. At round 1970 grams per ski for the 180 cm model, the Z-Line 90 falls proper across the center of the pack when it comes to weight when in comparison with different ~90mm-underfoot skis.

And we expect this weight makes good sense. The Z-Line 90 is a devoted resort ski, not a ski that you simply’ll use to set backcountry pores and skin tracks. So we expect holding a little bit of weight is an excellent concept because it helps skis deal with the tough circumstances typically encountered inbounds.

For reference, listed here are a couple of of our measured weights (per ski, in grams) for some notable skis. As all the time, remember the size variations to maintain issues apples-to-apples.

1585 & 1586 Head Kore 93, 180 cm (17/18, 18/19)
1790 & 1831 Salomon XDR 88, 186 cm (17/18, 18/19)
1839 & 1842 Black Crows Orb, 178.Three cm (17/18, 18/19)
1864 & 1882 Armada Invictus 89Ti, 187 cm (18/19)
1869 & 1894 Atomic Vantage 90 Ti, 184 cm (18/19)
1920 & 1940 Volkl Kendo, 177 cm (17/18, 18/19)
1931 & 1932 DPS Basis Cassiar 94, 185 cm (18/19)
1936 & 1954 Fischer Professional Mtn 86 Ti, 182 cm (17/18, 18/19)
1943 & 1968 Liberty VMT 92, 186 cm (18/19)
1959 & 1985 Renoun Z-Line 90, 180 cm (17/18, 18/19)
1996 & 2048 Head Monster 88, 177 cm (17/18)
1997 & 2001 Blizzard Brahma, 180 cm (17/18, 18/19)
2008 & 2015 Folsom Skis Spar 88, 182 cm (18/19)
2049 & 2065 Volkl Mantra M5, 177 cm (18/19)
2062 & 2063 Rossignol Expertise 94 Ti, 187 cm (18/19)
2077 & 2092 K2 Ikonic 84 Ti, 177 cm – weight consists of binding plates (17/18, 18/19)
2114 & 2133 Nordica Enforcer 93, 185 cm (17/18, 18/19)
2171 & 2176 Head Monster 88, 184 cm (18/19)


(1) Whereas the Z-Line 90’s form and rocker profile are just like a variety of devoted carvers, Renoun is claiming that the Z-Line 90 can even deal with off-piste circumstances. So is the Z-Line 90 extra versatile than its form may recommend?

(2) Plenty of 90mm-underfoot skis have dual-metal-laminate constructions just like the Z-Line 90, however none of them share the Z-Line 90’s HDT tech. So does the Z-Line 90 really feel considerably extra secure than different skis with comparable constructions and weights?

Backside Line (For Now)

Renoun calls the Z-Line 90 an all-mountain ski with the “heart and soul” of a carving ski. So whereas it initially seems to be fairly simple, it additionally options Renoun’s distinctive HDT, and Renoun is claiming that the Z-Line 90 can deal with circumstances everywhere in the mountain, not simply on-piste. So what’s the actual outcome?
