Dynafit SL 80 Ski


The days of mounting your old bindings on your kid’s old resort skis are a thing of the past. Maybe you convinced them to go touring with you on a setup that weighs 1/3 of their body weight, and maybe they even pretended to enjoy it. But now, thanks to the Dynafit SL 80, your kids have access to a proper backcountry ski that checks all the boxes: light, durable, fun, inexpensive, and offered in appropriate lengths. The micro sidewall that runs the length of the ski is good for durability, but it plays an even larger role in reducing chatter while simultaneously increasing grip. The tip notch makes sure that your groms learn to rip skins the proper way from the beginning while also protecting the core from head-on impacts. A generous amount of tip rocker paired with the perfect waist width ensure a fine balance between climbing confidence and descending prowess. Just as capable in the resort as in the backcountry, the Dynafit SL 80 is a confidence inspiring ripper that’s ready for anything.

  • Enough length options to get the perfect size or leave a little bit of space to grow into.
  • Tip notch allows for easy transitions in the backcountry, resort, or Tuesday night race.
  • Tip rocker, tail rocker, and a manageable flex.
  • Pairs perfectly with the ST Rotation 7.

Questions & Reviews

Question from Tjaard B
How do you compare these to the Hagan Boost Jr? How does the rocker profile compare? Pros or cons in the purpose made skins (for kid use, so easy hybrid glue a pro)?
Answer from Jeff
Tjaard, We have yet to get the new Boost Jr in, so I had to do some research. The Boost Jr has 220mm of tip rocker on the 135cm, he SL 80 has 240mm on the 139cm. So pretty similar. The Boost has more sidecut and a very short turning radius. I can't say how much difference any of that will affect kids having fun.
For skins ease of use is important. The only kid's specific skin we have is the Contour, which uses the less-sticky Hybrid glue. Also, they do not have a tail fix, which is easier to use as long as the end of skin stays clean and sticky. For older kids who may use them a lot, a tail fix may be better As always, Skimo carries a very full line of skin material and parts to custom make what will work best for your child.

Question from Eric S
Can you suggest the min/max weight for a person using the 158s? Looking for a replacement backcountry ski for my kid, but don't want him to grow out of them TOO soon. Bonus would be if they would suit his mom too, once he does grow out of them.

They are both excellent skiers.
Answer from TSB
Hey Eric, thanks for reaching out! I'd say the 158cm length as a touring ski is probably best suited to somebody between 115-135 lbs, although you could definitely stretch that window a bit if needed. If you wanted a "quiver of one" touring ski that would fit your son/daughter for a little longer and then transition over to being an adult ski for a smaller person, the Voile Hyper Vector comes in shorter lengths and a sweet mauve topsheet.

Question from Katie M
So I know these skis dont apply to this question, but I cant find the Womens Tour 88 on here so this is where I have landed. I am looking into buy a pure approach ski for super long approaches at altitude. Am I crazy for thinking that the Womens tour 88 would be perfect? I am toying with the idea of trying to put silvrettas on them and be able to ski in my mountaineering/ice climbing boots, (Please dont gasp at this idea like everyone else). If you think this is crazy please suggest something else, or just send some advice! Thanks!
Answer from Nate
Hi Katie, you definitely are not crazy. Colin Haley has been doing exactly what you propose for several years (along with other alpinists). My suggestion, if you are using them exclusively for approaches, would be to use a skimo race ski instead of a touring ski or kid's ski as you'll save substantial amounts of weight.

Feel free to email us at and we will be happy to continue the discussion and dial in your approach setup.
Answer from clarkboulder
Is it crazy to consider this ski in 158cm for my wife who is 5'4" and 112lbs? With a speed turn binding and Scarpa Alien boots? Will this ski just be too flimsy for her? I'd imagine not but not sure. Thanks
Answer from jbo
Hi Aaron, people seem to think they are crazy on this page! Don't worry, you're not. I got a pair for my wife of similar size :)
Answer from clarkboulder
Thanks! Oops I put my Q as an answer to Katie's Q. Oh well.
