2026 Rossignol Sender Free 100 and Dynastar M-Free 100 First Impressions and Comparison

It’s no secret that we’re fans of ~100 mm twin tips here at SkiEssentials.com, so this article and review is right up our alley. While one of these skis is entirely new, the other is a refinement and, we think, a huge upgrade over its predecessor. For 2026, Rossignol introduces their Sender Free 100, bringing the immensely popular Sender Free 110 into more of a park/all-mountain world while Dynastar implements the new Hybrid Core 2.0 and new length options into their M-Free 99, turning it into the all-new M-Free 100. While both skis are built from the sister companies of Rossignol and Dynastar, and both include the word “Free” in the name, and both state a 100 mm underfoot width, they ski, sound, and feel vastly different. While competitors in application, we found the Rossignol to have more of a park/freestyle theme to it while the Dynastar falls more squarely in the all-mountain/freeride segment.

From a construction standpoint, the Rossignol Sender Free 100 has a poplar core, Air Tip, and VAS vibration absorption system. We’re missing the Titanal Beam and Carbon Alloy Matrix in this ski but other than that, the skis are pretty much the same, just a dimension narrower overall. With this build, we get excellent energy, fantastic pop, wonderful mobility, and a lot of character. The more central mount point is totally obvious, and a certain nod to the park capacity and influence. It’s basically a mini version of the Freeride World Tour ski mixed with a park ski. Very interesting stuff here. We’re seeing stated weights of 2000 grams per ski in the 184, although we haven’t put one on our own scale as of this publication. It certainly feels lighter than 2kg, probably due to the Air Tip and the forward mount point. On the other side, the Dynastar M-Free 100 uses Hybrid Core 2.0 to power the ski and their Polyurethane layers along the sides to smoothen and lighten the process. So far, we’ve seen this Hyrbid Core 2.0 used in the M-Pro series and M-Cross, and as of last year, the M-Frees 108 and 112. This new 100 now gets the 2.0 treatment, and frankly it’s about time. By using three different layers in the wood core, Dynastar adds a ton of energy, grip, and power to the mix. Adding the PU along the sides smooths and quiets the ride. While the thought of plastic in a ski can be a bit disconcerting, it’s tough to look past the actual performance—this stuff works great in skis and delivers a signature feel and sound. Dynastar states a weight of 1800 grams per ski in the 185, although again, we have not put a ski on the scale. To us, the PU creates the stability to make this ski feel a bit heftier, and as a result, smoother although we do not find that it lacks mobility at all.

In terms of shaping, we’re seeing some very similar numbers. In the M-Free, the 185 hits 131/101/123 mm resulting in an 18-meter turn radius. Rossignol puts their dimensions at 131/100/121 in the 184, and to them, this lengthens that arc to a stated 20-meters. It’ll be interesting to see when we get both skis how they compare base to base to see if there’s really much of a difference at all. The taper shape and rocker profile are a bit more dramatic on the M-Free 100, with a longer taper shape and higher camber height. This camber makes the M-Free slightly more energetic in turns and with a more directional mount point, a smoother carver. A bit flatter, and with a more central mount, the Sender Free 100 is a park skiers dream, with a smooth and powerful feel mixed with twin tip creativity.

On snow, we are loving the new M-Free from a stability and power standpoint. The older M-Free 99 was a great ski, but the new construction takes it to the next level. Edge grip, carving power, and rebound are all increased, making this a formidable ski in a very popular category. This new ski can hold its own with some more famous competition, as we’d put it right up there with a Nordica Unleashed 98, Salomon QST 98 (and the new 100) or as a considerably more powerful Atomic Bent 100 or Armada ARV 100. It’s still going to fall short of heavier hitters like Black Crows Justis or Blizzard Rustler 10, but for no metal, this is a very impressive ski. On the flip side, you’re going to miss out on some park performance, as it’s not quite Line Chronic 101 or K2 Reckoner 102 in terms of playfulness, flex, and creativity, but that seems to be an acceptable trade for the blend of attributes that this ski possesses. The ski isn’t quite as capable in a park setting, although if it’s not a top-priority, you can certainly get away with park laps from time to time. It’s more that the ski really excels in an all-mountain and freeride format more so than it suffers in a pure park application. After a few runs, the most notable difference was in the on-trail carving power and smoothness of the M-Free 100 as a standout while the Sender Free 100 had more playful pop and freestyle energy. It’s amazing, we’ve found, that skis with such similar shapes and reasonably similar builds can feel so different.

The highlight of the new M-Free 100? It's upgraded propensity for on-trail carving.

Overall, it’s great to see two new 100 mm twin tips enter the market. The M-Free, for years, has seemed to be just an inch away from being great and totally awesome, and Dynastar has finally cleared that last hurdle. For Rossignol, the secret formula is in taking an existing winner in the Sender Free 110 and paring it down to accommodate a more creative and freestyle-oriented group. This is not to say that there’s no crossover here between the two, they are, after all, very similar and competitive skis with each other. With different sounds, feels, and applications, the two differentiate enough to warrant their existences and we’re happy for both.
