Salomon MTN Summit 79 Ski

When Salomon's X-Alp ski hit the market back in 2017, it immediately garnered a loyal following for its ability to sprint up the skintrack at near-race speeds, while keeping the descents more fun and playful than we'd assume from a hard-snow-oriented mountaineering ski. Rarely had a ski appealed so well to efficiency-conscious skimo athletes and mach-looney-loving freeriders alike, and the X-Alp proved to be an easy-skiing, fast-ascending option for racers looking for a wider touring ski and non-racers wanting a tool for spring conditions. Not much has changed for Salomon's goldilocks low-fat ski, with the MTN Summit 79 making minor tweaks to keep torsional stiffness and hard-snow performance at a maximum. While the original X-Alp received high marks for its easy-turning feel and great performance in powder, the ski could also feel noodly when conditions firmed up, especially for bigger or less balanced skiers. With the move from a basalt/fiberglass cap construction to a monocoque-carbon, partial-sidewall construction, the MTN Summit gains some of the bulldozing stability of its older siblings in the MTN Explore line while maintaining the technical precision that makes it a great choice for difficult skiing at high altitudes. Pair the MTN Summit with race boots and mohair skins and watch full-day tours turn into dawn-patrol laps, fueling the fire for bigger peaks and more ambitious objectives.

  • Not as demanding as other mountaineering skis, the MTN Summit 79 brings tons of fun to the low-fat category.
  • Karuba wood-core adds damping to a precise monocoque carbon chassis.
  • Pairs well with race boots for speed, race-plus boots for versatility, and even standard touring boots for daily-driving.
  • While the X-Alp branched off from Salomon's race-ski lineage, the MTN Summit 79 is more in line with their touring skis, the MTN Explore 88 and 95.
  • Rockered tip with race-skin notch means the MTN Summit goes from weeknight racecourse to weekend powder lapping and back again.
  • Glossy topsheet goes well with Capilene sun-hoodies and midsummer trips to the glacier.

Questions & Reviews

Question from Joel
Heya! I'm debating between this and the Atomic UL 78 for a lightweight summer couloir mission ski (including a lot of ski carrying). Even when coming from a freeride background, I'm still kind of tempted to go for the weight savings of the UL. My question is, how much stability difference there really is in those 150 grams?

Any other attributes that I should pay attention to between these skis? The partial sidewall does sound enticing. At 5'10 and 140 lbs, the 170cm length is what I'm gravitating towards.

Thank you in advance!
Answer from eric
Joel-Great question, the Summit is a bit softer and rounder flexing ski than the UL. Which should make it easier to ski or a little better in punchy snow. The UL 78 is a little stiffer but i dont think it lacks in stability, maybe just some float in mushy snow.

Question from Sean M
Hi all, I'm looking to get a light pair of skis for ski mountaineering and these seem to fit the bill. However, I'm wondering if 170cm is really long enough since I'm 184cm tall and ca. 81kg. I currently tour with the Blizzard Zero G 95 at 177cm and quite enjoy them.
Answer from Zak M
Hey Sean, I am also 184cm and have owned ski mountaineering skis from 169-172cm and find that height pretty excellent. Overall that hits me right around nose height. That length is easy on the up and for doing technical jump turns and tricky sidestepping during descents the shorter length is quite versatile. Sure, skiing at higher speeds might feel a bit less confident but it's always give and take with this category of skis. Let us know if you have any more questions!

Question from Ryan
I'm torn between this and the Black Crows Mentis Freebird as my light and fast/long/spring touring option that can still ski real downhill. I want something to do a <24 hr tran-Sierra crossing this spring/volcanos/do it all around. The Mentis seems untested, but appealing and both are designed to go downhill still for the weight. I'm looking for a local demo if possible, but curious if anyone has got a chance to compare these? Open to other suggestions!
Answer from eric
Ryan- We have not skied the Mentis yet. Previous Black Crows skis in this category have been underwhelming. We can speak that the Salomon is a very solid performing ski with a relaxed tail that would fit your intended use very nicely.

Will M (used product a few times)
After being shamed by my fellow Skimo Co employees for not owning a sub 90mm ski, I decided to give this thing a try. No more name-calling now!

While it's not a race ski or even a race plus, it is the skinniest ski I've ever skied. That being said, I was quite surprised by the performance it offered.

It's about as squirrely as I had assumed something this light and skinny would be. However, it wasn't overwhelming by any means. I've gotten out on it a few times now and have been pleasantly surprised by how well it has handled absolutely terrible snow. From wind buff to refrozen tracks, these skis have not skied a single day of quality snow. But I think that's a good thing. Almost all skis would ski well in beautiful corn.

They're softer than something like the Dynafit Backlight series, but not too soft. They can hold an edge quite well on steep, icy terrain.

I'm excited to bring these tiny toothpicks up to the PNW to see how they fare on the North American portion of the Ring of Fire.

Question from Katie
Wondering about which length ski to get for the MTN Summit 79. I'm a female at 5'8" and weigh 125 lbs., and am a competent athlete and fairly aggressive skier.
Answer from jbo
Hi Katie, the 164 would be the sweet spot for you, it's a very fun ski!

Question from Jim

I have a set of the Salomon MTN Summit 79 in 164 length. Any pre cut skins from Salomon coming your way. And if not, do you have a skin to recommend?
Answer from Zak M
Hey Jim, unfortunately, we are not carrying a pre-cut skin for the MTN Summit 79. There are potentially a few options that could work out using some other pre-cut skins but potentially your best option would be building a custom one. If you wanted to email us at help@skimo.co we could set you up with the right combination. Thanks

Question from Tim C
expecting that a tr2 would not be your 1st choice on this ski, but asking as some of the skis have mounting location restrictions. from your shop, I own the tr2 on a set of zero g 85 and also have a set of Dynafit Speed Turn on a pair of Hagan Cirrus having all four cap/sidewalls ripped away from the ski under the boot area for several seasons now. I also have a Atomic 78 ultra with vipec. Being a bit fond of the tr2, but needing to replace the quick turning and playfull but damaged 163 cm Hagan Cirrus before the edges rip out and snag something mid run.
Answer from Teddy Young
I agree that you could go with a different/lighter binding on this ski, but the TR2 is a fantastic, unique binding! As far as mounting locations, the long hexagon shapes on the top sheet indicate where the toe/heel are intended to be mounted. As long as you're within those shapes, you should be good to go!
