This year WNDR Alpine introduced a new ski to their lineup, the Vital 100.

You can listen below to our GEAR:30 conversation with WNDR’s Matt Sterbenz, Pep Fujas, and Xan Marshland for the full story behind the Vital 100 (and all the new algae-derived materials it uses).

But to summarize, the Vital 100 is the lighter and narrower complement to WNDR’s Intention 110, with the 100 being targeted more at shallower / firmer conditions, technical terrain, and longer days in the backcountry.

We just got a pair of the Vital 100 and personally, I’m quite excited about it. In the category of ~100mm-wide touring skis, there aren’t a whole lot out there that seem really similar to the Vital 100, and I think that has the potential to be a good thing for certain skiers.

What WNDR Alpine says about the Vital 100

“The ALL-NEW Vital 100 is your ski for alpine conquests – a precision tool for situations where edge hold is paramount. Featuring our proprietary AlgalTech™ ski materials platform.

Impressively stable for its weight, this ski charges intuitively in any condition, while remaining easy to pivot for technical maneuverability. The secret of the Vital 100’s unique performance characteristics lies in the integration of advanced biobased materials, which allow it to punch above its weight class in any terrain.”

This seems like a sensible description, based on the Vital 100’s design elements that we’ll get into below. Like most brand’s 100mm-wide skis, WNDR Alpine is emphasizing both the Vital 100’s versatility and its edge hold on firmer conditions. And while we’re always wary when any brand claims that their lightweight backcountry skis “charge in any condition,” I think WNDR has reason to make the claim when comparing the Vital 100 to the rest of the touring-ski market.

As for their “AlgalTech” materials, that warrants some more explanation:

Construction & WNDR Alpine AlgalTech

Since they launched just a little over a year ago, WNDR Alpine set themselves apart from the rest of the competition by using materials derived from algae in their skis. In their first iteration of the Intention 110, this was in the form of Polyurethane stringers in the core that were created from oils made by microalgae, rather than fossil fuels.

WNDR Alpine's "Algal Core"

In their 20/21 lineup (Vital 100 & Intention 110), they’ve taken a few notable steps in terms of increasing the bio-based materials in their skis. The 20/21 Vital 100 and Intention 110 still feature a domestically sourced aspen wood core and those algal PU stringers, but they also now have liquid-poured, algal PU sidewalls.

In addition to being made from algae-derived oils, those PU sidewalls also reportedly bond to the wood core without any adhesive, and they also reduce waste since they can be poured into channels with little excess material needing to be trimmed away. (WNDR says they eliminate about 2 lbs / 907 g of waste per ski with their construction, relative to more traditional ski constructions.)

WNDR also started using a “bio-based resin” for the layup process. Dubbed “Super Sap” and produced by Entropy Resins, this resin has been used by some skateboard and surfboard companies, and it’s cool to see it entering the ski world.

So, what does that actually translate to when you’re out in the backcountry? Well, in addition to reducing the environmental impact of their skis, WNDR says their AlgalTech construction also improves their skis’ strength-to-weight ratio, torsional rigidity, and damping characteristics. I.e., they’re supposed to ski better than more traditional constructions.

Unique construction aside, let’s get into the more basic design elements of the Vital 100.

Shape / Rocker Profile

The Vital 100 looks pretty similar to the Intention 110, but with a few tweaks that you’d expect when comparing skis of these different widths.

First, just like the Intention 110, you can get the Vital 100 with a rocker / camber / rocker profile, or with a fully reverse-camber profile. Apart from custom skis, I can’t think of any current, stock skis on the market in this class that give you that option.

Right now we have the cambered version of the Vital 100, and unsurprisingly, it has slightly shallower tip and tail rocker lines than the cambered Intention 110. The Vital 100 also has slightly lower tip and tail splay than its wider sibling.

Compared to other touring skis in roughly the same class, the Vital 100 has a deeper tip rocker line and higher tail splay than most (e.g., K2 Wayback 96, Armada Tracer 98, G3 FINDr 102). While this has nothing to do with what WNDR is claiming about the Vital 100, its rocker profile does make me really curious about how playful it will feel, given that the Intention 110 was a ski that catered well to a more playful skiing style (while also working just fine when skied with a more directional approach).

As for shape, again, the Vital 100 looks pretty similar to the Intention 110, but the narrower ski features a bit less tip and tail taper. Give that WNDR is highlighting the Vital’s edge hold, that makes sense.

I really like the look of the Vital 100’s shape. It’s not super tapered, which makes me think it should carve and hold and edge pretty well. But it also has some taper and doesn’t look like a shape that will feel hooky in weird snow conditions (which you’ll often encounter over the course of a full, spring touring day). We shall see…

Flex Pattern

Here’s how we’d characterize the flex pattern of the 183 cm Vital 100:

Tips: 6
Shovels: 6-6.5
In Front of Toe Piece: 7-9.5
Underfoot: 10
Behind the Heel Piece: 10-8.5
Tails: 8-7

Overall, the 183 cm Vital 100’s flex pattern feels very similar to the 185 cm Intention 110. The most notable difference is that the Vital 100’s tips start slightly softer, and its flex doesn’t ramp up quite as quickly as you move from the shovels to the middle of the ski. But this ski is still very strong around the bindings, and I love that its tail isn’t drastically stiffer than its tips.

In the world of ~100mm-wide touring skis, it seems like most of them feature pretty directional flex patterns (i.e., soft tips and much stiffer tails). So, along with skis like the Line Vision 98 and Armada Tracer 98, this is another area where the Vital 100 stands out.

Overall, the Vital 100’s flex pattern feels pretty moderate — I wouldn’t call this ski particularly soft, and I also wouldn’t call it super burly.

Mount Point

Like the Intention 110, the Vital 100 has a recommended mount point that’s a bit closer to center compared to the rest of the market.

At -6.7 cm from true center, the Vital 100’s mount point is fairly in line with skis like the Moment Wildcat Tour 108, Line Vision 98, and Atomic Bent Chetler 100, and notably closer to center than some more traditional skis like the G3 FINDr 102, Blizzard Zero G 105, and Line Sick Day 104. That said, the Vital 100’s mount point is still farther back than most freestyle skis.

We found the Intention 110 to be versatile in terms of allowing you to ski it with a pretty forward stance, or a fairly centered one, and I’d expect the same of the Vital 100, given its similarities to the Intention 110.


WNDR Alpine makes skis for backcountry touring, so it makes sense that their skis are generally lighter than most inbounds-oriented options.

With that said, the Intention 110 and Vital 100 are not the lightest skis out there. In a rare occurrence, the measured weight for our pair of the 183 cm Vital 100 is within a gram of WNDR’s stated weight: 1840 grams per ski.

So, looking at touring skis like the Salomon MTN Explore 95, G3 FINDr 102, and Armada Tracer 98, the Vital 100 is notably heavier. If you want the absolute lightest ski in this class, the Vital 100 isn’t going to be for you.

But for those who want to ski hard on their ~100mm-wide touring skis — or who just appreciate a ski that doesn’t feel super chattery and harsh on firm snow — I think the Vital 100’s weight is going to be very appealing.

Its weight is fairly similar to the Line Sick Day 104, Atomic Bent Chetler 100, and Liberty Origin 96, all of which are skis that we think ski really, really well for their weight — to the point that we’re happy using them for laps in the resort.

We also found that the 19/20 Intention 110 offered an excellent stability-to-weight ratio, and all of this makes WNDR’s claims about the Vital 100 being about to “charge in any condition” more reasonable (at least when comparing it to the touring-ski market).

For reference, here are a number of our measured weights (per ski in grams) for some notable skis. Keep in mind the length differences to try to keep things apples-to-apples.

Some Questions / Things We’re Curious About

(1) Given its construction and light-but-not-super-light weight, just how stable and damp will the Vital 100 feel?

(2) On that note, since so many inbounds-oriented skis are so light these days, could the Vital 100 serve as a 50/50 or even dedicated inbounds ski for folks who prefer a lighter setup in the resort?

(3) Most touring skis in this width are pretty directional, traditional designs, so will the Vital 100’s more progressive mount point, round flex pattern, and / or deeper rocker lines make it work well for those who prefer something slightly more playful and / or forgiving?

(4) WNDR is highlighting the Vital 100’s performance in steep, technical terrain. So just how well will it perform there compared to the competition, and how versatile will it feel outside of that particular end-use?

Bottom Line (For Now)

I’m itching to get on the new WNDR Alpine Vital 100. Its moderate shape, rocker profile, and flex pattern all make me think that this could be an intuitive, versatile ski. Add on its unique, algal-derived construction and slightly more progressive mount point, and it definitely stands out in the current touring-ski market.

We will be getting the Vital 100 mounted and on snow as soon as we can, so stay tuned for updates this season.

  1. There unfortunately seems to be a pattern emerging of weight gain with their skis. Last year the Intenion 185cm was 1800g. This year it is 2kg and it’s skinny Vital brother at 183cm is still heavier at over 1800g. I may well have purchased one or both, but at these weights neither.

    • It’s honestly great to see you picking up on that trend. I can assure you this not overlooked in the design of the Vital and Intention. The extra weight (approx 150gr) is the result of replacing the paulownia over edge with aspen. This change can be accredited to 3 key considerations: 1. Paulownia is from China (at least thats where ours was coming from) and aspen is a local resource we have clear visibility to the harvesting, transportation impact whereas we have no clue how its harvested in China, and we ocean freight it over, truck and rail it from the coast to Utah – excessively carbon rich for our environmental consciousness, 2. We didn’t like how the paulownia was fracturing in 3pt bend tests. Every complete layup composition tested, at several areas along the ski, propagated at fracture line and at less force than we were able to achieve with aspen. The aspen withstood more force, and at failure, was always a clean, perpendicular fracture. 3. (and lastly for now) is that paulownia is an airy wood species, that sinks a lot of moisture, at varying levels. We could air the cores out, then come back the next day and moisture would move back in. Our new Algal Wall cast urethane sidewall we developed exceeds extruded plastics for this application but has a negative reaction to moisture (as does all urethanes). To get a super homogenous result, the facing wood needs to be dry and uniformly dense, as the process is moulded in liquid form. This process is superior in strength and less wasteful as we therefore eliminate any additional bondline adhesives and waste from profiling extruded plastics. I know thats a mouthful, and just speaks to how much thought, and development when into this change in weight. Personally I feel these are still (at 150gr) heavier, the lightest skis I’ve ever felt – and thats largely due to the fact our stiffness, and weight is centered underfoot, providing an unexpectedly light swingweight. Sure on the pack is where there is little argument, but unless you’re running the bungee-cord-over-the-shoulder-alta-patroller-sling and voile-strap-probe-to-the-shaft-ultraminilist-kit for your avy equipment, I’d bet we all have a extra pound or two we could live without so whats an extra 150grams in the end to get a better downhill experience. Thanks for keeping us honest!

      • Thank you for the detailed and thoughtful reply.

        I appreciate all the factors that went into that decision.

        I’m a fan of what you’re doing at WNDR and hope your innovations and mindset continue to spread across the Ski Industry.

        As for the Vital. My buddy Jack Stauss, has been singing its praises, and it is hard to not look at my current ~100mm setup and go all in on the upgrade to the Vital. Frankly the blend of tech and environmental consciousness will probably push me over the edge and I’ll have a pair (if supplies last) by the time spring touring season rolls around.

        Thanks again for the work you’re doing.

  2. I think of this very highly, as WNDR is more than correct with the fact that ski industry in general is everything else than green. With regards to resin systems, and many other things, the story is however a bit more complicated and differentiated than stated. Entropys Super Sap says “biobased”, which is – well, true and not true. The mixture is actually using 31% biobased materials, or the other way round is 69% petrol based. Which I think is a great start, but not exactly green. Then again digging deeper, our experience is that epoxys of course need to meet production/technical quality criteria, but also workplace safety concerns are important. Here again the story is a bit trickier than “green/not green” again. In epoxy, the primary health or workplace risk comes mostly from the hardener, and different additives added to achieve desired properties. Our experience is that phenolic fasteners, volatile solvents and certain amines are very critical; as such we use a mix that does not contain any of these groups. Entropy Super Sap contains Bisphenol-A, which is why we opted out of it in the first place. So maybe I get a bit nerdy on that stuff, but there’s so much to educate consumers about, and a lot of greenwashing in this industry, so I hope a differntiated perspective is valuable.

    • Thanks for the praise and perspective, and huge respect to what your team is doing across the pond!

      You’re absolutely right that the story is trickier than simply saying “green or not green.” It’s not a binary. Of course, we’ll always choose a 31% biobased resin over a 0% biobased one if we can verify internally that it hits the performance characteristics we desire. But we’re also excited for opportunity to improve. The path we’re on is one of iteration and refinement within the entire ski’s construction. Our own algae-derived materials are helping us move the needle on both ski performance and resource use simultaneously, and ultimately, that gives us a lot of hope for the future. Keep on nerding out and keep on innovating!

  3. I’m very much hoping you guys get a chance to try the reverse-camber version for a few test runs and give us a comparison. And to the reverse- camber Black Crowes Daemon, which seemed to me like one of the easiest skis I’ve ever been on…
