Outside 2019 Ski Test: Real-World Data, Unfiltered Terrain, and Why This Year’s Results Changed How We Choose Skis

Outside Magazine’s 2019 Ski Test remains one of the most methodologically rigorous and transparent ski evaluations ever published. Conducted over 12 days across two contrasting Wyoming resorts—Jackson Hole Mountain Resort (elevation: 10,450 ft summit; vertical drop: 4,139 ft) and Grand Targhee Resort (elevation: 9,850 ft summit; vertical drop: 2,200 ft)—the test evaluated 147 skis from 32 brands, including Atomic, Blizzard, DPS, Kästle, Line, Nordica, Rossignol, Salomon, Volkl, and Armada. Each ski underwent standardized testing by 42 certified instructors and expert recreational skiers with verified FIS-level race backgrounds or 15+ years of backcountry guiding experience. Unlike consumer-driven reviews, Outside employed a dual-scoring system: objective data (measured via GPS-tracked turns, edge grip sensors, and flex profiling) and subjective scoring across six criteria—carving, float, stability, playfulness, versatility, and forgiveness—with each rated on a 1–10 scale. The result wasn’t just rankings—it was a functional taxonomy of modern ski design.

The Testing Ground: Why Jackson Hole and Grand Targhee?

Choosing terrain is as critical as choosing testers. Jackson Hole provided high-speed, variable-hardpack conditions on the lower mountain (Rendezvous Bowl’s groomed runs averaged 12°–18° pitch with snow density readings between 0.28–0.33 g/cm³), while its upper mountain delivered wind-scoured ice, boilerplate, and intermittent powder stashes averaging 12–24 inches of settled snow. Grand Targhee offered the counterpoint: consistent light-density powder (0.09–0.14 g/cm³), sustained tree skiing on pitches ranging from 16° to 32°, and low-angle glades where maneuverability and early-turn initiation mattered more than top-end speed.

This geographic duality exposed design weaknesses that single-resort tests miss. For example, the 2019 Kästle MX88 (163 cm) demonstrated exceptional edge hold on Jackson’s icy Corbet’s Couloir approach but buckled under torsional load during tight-radius turns in Targhee’s dense spruce forest—revealing its 22 mm sidecut radius limitation at slower speeds. Conversely, the Line Sick Day 94 (172 cm) excelled in Targhee’s trees but vibrated noticeably above 38 mph on Jackson’s open bowls due to its minimal metal laminate (single 0.3 mm Titanal layer).

Test Protocol: Beyond Subjective 'Feel'

Each ski was tested for a minimum of 4.2 hours per tester across both resorts. GPS units recorded turn radius, speed differential, and lateral acceleration. Edge grip was quantified using custom-mounted piezoelectric sensors embedded in boot soles that measured micro-slip events per turn—recorded as ‘slip count’ (SC). A SC value ≤ 0.8 per turn indicated elite edge control; values ≥ 2.4 signaled instability. Flex profiles were mapped using a 3-point bending rig calibrated to ±0.05 mm accuracy, generating stiffness curves from tip to tail at 5 cm intervals.

Testers wore identical Lange Comp 130 boots (last: 98 mm; forward lean: 14°) and mounted bindings to ISO 11088 standards with DIN settings fixed at 9.5 for all testers regardless of weight or ability—a deliberate choice to isolate ski behavior rather than equipment variability. No ski was allowed to be remounted mid-test. This eliminated ‘sweet spot’ bias and forced evaluation of true mounting compatibility.

Performance Categories & Real-World Implications

Outside segmented skis into 12 functional categories—not marketing labels. These included: Powder Chargers (waist width ≥ 115 mm), Frontside Carvers (waist ≤ 82 mm, sidecut radius ≤ 14 m), All-Mountain Mavericks (85–105 mm waist, multi-radius sidecut), and Touring Hybrids (weight ≤ 1,850 g per ski, ASTM F2912-22 certified for uphill efficiency). The categorization directly impacted scoring: a ski could not score highly in ‘Carving’ if its sidecut radius exceeded 16.5 m—even if testers loved it.

Top Performers by Metric

The 2019 test crowned the Blizzard Rustler 10 (182 cm) as the highest-scoring All-Mountain Maverick (average score: 9.1/10), praised for its balanced flex (tip: 52 N/mm, mid: 78 N/mm, tail: 64 N/mm) and symmetrical carbon-spine construction. Its 98 mm waist, 17.2 m sidecut radius, and 2.5 mm camber underfoot delivered predictable edge engagement without sacrificing soft-snow agility. In contrast, the Rossignol Experience 88 Ti (172 cm) topped Frontside Carvers with a 12.8 m sidecut radius and 1.8 mm camber point—achieving a blistering 0.42 SC average on icy groomers at Jackson, outperforming the Volkl Deacon 8 (170 cm) by 0.19 SC points despite identical stated dimensions.

For Powder Chargers, the DPS Wailer 112RP (184 cm) earned top marks not for width alone (112 mm underfoot), but for its progressive taper (tip-to-tail width ratio: 1.58) and 20° tip rocker—enabling effortless pivot in Targhee’s tight chutes while maintaining directional stability at speed. Its measured swing weight (227 g·cm²) was 14% lower than the comparable Black Crows Navis Free (184 cm), explaining its superior quickness in transition-heavy terrain.

Material Science Breakdown: What Actually Works

Composite construction dictated outcomes more than branding. The test revealed three material patterns with statistical significance (p < 0.01):

• Skids with dual Titanal layers ≥ 0.5 mm thick consistently scored ≥ 0.9 points higher in Stability than single-layer counterparts—regardless of waist width.
• Skis incorporating carbon fiber in the tip/tail (not just the core) reduced swing weight by an average of 18.3% versus fiberglass-only models of equivalent dimensions.
• Wood cores composed of >65% poplar (by volume) demonstrated 22% greater dampening at speeds >35 mph than ash-dominated cores—critical for Jackson’s high-speed descents.

The Nordica Enforcer 104 (179 cm) exemplified this: its 0.6 mm twin Titanal laminates, poplar-ash-paulownia hybrid core (72% poplar), and carbon-fiber-reinforced tips produced the lowest vibration amplitude (0.82 mm RMS) of any ski tested. Meanwhile, the Armada Tracer 98 (177 cm), with its single 0.3 mm Titanal sheet and 90% paulownia core, registered the highest measured chatter (2.14 mm RMS) on firm snow—despite receiving high subjective scores for ‘playfulness’.

Flex Profile Anomalies

One unexpected finding involved flex symmetry. While 87% of tested skis claimed ‘progressive’ flex, laser displacement mapping showed only 31% achieved true linear progression from tip to tail. The Salomon QST 99 (177 cm) had a measured flex curve deviation of +14% at the shovel—explaining its tendency to dive in deep powder despite its 99 mm waist. Conversely, the Atomic Vantage X 80 CTI (163 cm) exhibited near-perfect linearity (±2.3% deviation), contributing to its #1 ranking in Frontside Carving consistency across all 42 testers.

Binding Compatibility & Mounting Realities

Mounting position dramatically altered performance—and not always as advertised. Outside mandated factory-recommended mount points, but recorded how often testers spontaneously adjusted them. Of the 147 skis, 63% were remounted by at least one tester during the week. The most frequent adjustment? Moving bindings -1.5 cm forward on skis with ≥ 100 mm waists—an action that improved pivot initiation in trees by 31% (measured via turn initiation time: 0.42 s vs. 0.61 s at stock position) but degraded high-speed stability by 12% (increased slip count by 0.31 per turn).

The test also exposed binding-ski interface flaws. The Marker Griffon 13 ID (used on 82% of test skis) generated measurable pre-release events on the Volkl Mantra M5 (177 cm) when subjected to abrupt edge-set transitions—captured via high-speed motion capture at 1,200 fps. This occurred exclusively with the Mantra’s 2.2 mm camber profile and stiff tail (flex: 94 N/mm), suggesting camber height interacts critically with binding elasticity.

Weight vs. Performance: The Hard Numbers

Weight remained a persistent myth-buster. While lightweight touring skis like the Dynafit Blacklight Pro (172 cm, 1,480 g/ski) excelled in uphill efficiency (measured ascent time per 100m vertical: 42.1 s), they scored lowest in Stability (5.2/10) and Forgiveness (4.7/10). But crucially, weight did not correlate with ‘playfulness’. The heaviest ski tested—the Kästle FX106 (184 cm, 2,310 g/ski)—ranked #2 in Playfulness due to its ultra-low swing weight (231 g·cm²) and torsional softness (42 N/mm). Meanwhile, the lightest all-mountain ski—the Head Kore 93 (172 cm, 1,590 g/ski)—scored lowest in Carving (6.1/10) because its ultra-light paulownia core lacked the damping needed for clean edge hold.

A clear threshold emerged: skis weighing <1,700 g/ski consistently scored below 7.0 in Stability on firm snow unless they incorporated ≥ 0.4 mm of metal. The 2019 test confirmed that sub-1,700 g is viable for powder or touring—but demands material compensation elsewhere.

Market Impact & Lasting Revisions

The 2019 test triggered tangible industry shifts. Within 12 months, 17 brands revised their stated sidecut radii after Outside published raw GPS-derived turn radius data—proving many ‘17 m’ skis actually performed at 19.3–21.7 m in real-world arcs. Blizzard increased Titanal thickness in the Rustler 10’s 2020 iteration from 0.45 mm to 0.52 mm based on stability feedback. Rossignol re-engineered the Experience 88 Ti’s flex pattern after testers flagged inconsistent tip response—resulting in the 2020 model’s improved shovel stiffness (+11%) and reduced tail stiffness (-7%).

Most significantly, Outside discontinued ‘Best Overall’ awards after 2019. Their editorial team concluded that such labels obscured functional tradeoffs: a ski scoring 9.4 in Float but 5.1 in Carving isn’t ‘worse’ than one scoring 7.8 across all metrics—it serves different missions. Instead, they introduced ‘Mission Match Scores’, calculating compatibility percentages against user-defined priorities (e.g., ‘80% powder, 20% groomers’).

What Didn’t Work—and Why

Several hyped technologies underperformed. Carbon stringers marketed for ‘energy return’ showed no statistically significant improvement in rebound velocity (measured via force plate analysis) versus fiberglass equivalents. The ‘rockered tail’ design used on 23 skis—including the Line Supernatural 100—produced 19% more tail washout in tracked powder than traditional camber tails, increasing recovery time by 0.28 seconds per turn. And ‘variable flex’ claims proved misleading: only 4 of 32 skis advertising ‘adaptive flex’ showed measurable variation (<5% stiffness difference between slow and fast inputs) under lab-controlled loading.

The biggest disappointment was the widespread failure of ‘all-in-one’ marketing. Skis labeled ‘All-Mountain Freeride’ averaged 1.7 points lower in Forgiveness than dedicated All-Mountain models—suggesting design compromises eroded usability for intermediate skiers. The Faction Dictator 3.0 (184 cm), for instance, scored 8.9 in Stability but only 4.3 in Forgiveness, making it inaccessible to skiers below expert level despite its 96 mm waist.

Practical Takeaways for Skiers

Forget marketing narratives. Your ski choice hinges on three measurable factors: your typical terrain’s snow density, your average turn radius, and your preferred speed range. If you ski primarily at resorts with hardpack (density > 0.25 g/cm³), prioritize dual-metal construction and camber dominance. If you’re in the Rockies or Wasatch where powder averages 0.11–0.13 g/cm³, look for progressive taper (>1.55 ratio) and tip rocker ≥ 18°. And if your turns rarely exceed 25 mph, avoid skis with sidecut radii > 16 m—they’ll feel sluggish.

Also, match ski length to function—not height. At Jackson Hole, testers on 182 cm skis averaged 22% faster descent times on open bowls than those on 172 cm skis of identical model—yet in Targhee’s trees, the 172 cm group completed 37% more turns per run. There is no universal ‘right length’. There is only right length for your mission.

Finally, consider swing weight over total weight. A ski can weigh 2,100 g but have low swing weight (e.g., Kästle FX106: 231 g·cm²) and feel nimble. Another at 1,750 g may have high swing weight (e.g., Nordica Santa Ana 110: 298 g·cm²) and feel sluggish. Swing weight predicts maneuverability far better than grams alone.

2019’s Most Underrated Skis

Beyond the top rankings, several skis delivered exceptional value:

• Elan Ripstick 96 (174 cm): Scored 8.4 overall—highest among sub-$700 skis. Its Amphibio profile (asymmetric sidecut) yielded 12% tighter carved turns than symmetrical competitors.
• Head Wild Joy (163 cm): Top scorer for women (9.0/10) due to its 102 cm turning radius and 1.2 mm camber pocket—ideal for shorter-radius, high-edge-angle carving.
• Black Crows Corvus (180 cm): Though heavy (2,240 g), its 115 mm waist and 24° tip rocker made it the only ski scoring ≥ 8.5 in both Float and Stability—validating its ‘big-mountain’ positioning.

These skis succeeded not by chasing trends, but by solving specific problems: the Ripstick addressed affordability without sacrificing engineering, the Wild Joy optimized for anatomical leverage differences, and the Corvus refused to compromise on either float or control.

The Outside 2019 Ski Test endures because it treated skis as engineered tools—not lifestyle accessories. It proved that performance lives in millimeters of camber, grams of titanium, and degrees of taper—not in slogans. For skiers tired of guessing, the data remains actionable: use measured swing weight to assess agility, demand verified sidecut radius over marketing claims, and choose terrain-specific construction over universal promises. The mountains don’t care about brand heritage. They respond to physics—and the 2019 test mapped that physics with uncommon precision.

Skiers who studied the full dataset—especially the 28-page methodology appendix detailing sensor calibration protocols and inter-rater reliability coefficients (Cronbach’s α = 0.89 across all six scoring criteria)—reported 34% higher satisfaction with new ski purchases in the following season. That’s not anecdote. That’s evidence.

Testing conditions weren’t idealized. Temperatures ranged from -22°F to 28°F. Wind gusts hit 68 mph on Jackson’s tram summit. Snowfall varied from 0 inches to 18 inches overnight. Yet the data held. Because rigor isn’t about perfect conditions—it’s about controlled variables amid chaos. And that’s what makes the 2019 test a benchmark, not a snapshot.

When evaluating skis today, ask first: Was it tested across density gradients? Were flex profiles physically measured—not estimated? Did slip events get quantified, or just described? If the answer is vague, look elsewhere. The 2019 test set the standard—not for perfection, but for accountability.

No ski won ‘best in show’. But dozens earned respect—for doing exactly what their design promised, under pressure, in places where marketing evaporates and physics takes over.

The numbers don’t lie. And neither do the mountains.
