FIS Race Ski Sizing Guidelines

FIS regulations change frequently, so it is best to consult with your coach or local ski expert before making a final purchase. Please see the current FIS Specifications for Competition Equipment and USSA/FIS Equipment Rules for specific age and circuit rules.

NON-FIS Race Ski Sizing Guidelines

There are varying opinions on how to best size skis, but the most accurate method to size race skis is based on the athlete's weight. The chart below recommends what size should work best for young athletes using one pair of skis for both events and athletes using Slalom (SL) and Giant Slalom (GS) specific skis. If an older athlete is using one pair for both events, it is best to choose an SL ski that is one size longer than the ideal SL length. A long SL ski will still work for SL and be very serviceable for GS. These are loose guidelines, and you should consult your local coach or ski expert for more specific recommendations.

Sizing Considerations:

  1. Consult FIS, USSA, and other level appropriate regulations.

  2. Racer's ability level and preference - more advanced skiers can generally handle longer length skis which can be more stable at higher speeds.
  3. Growth of the athlete - you may want to consider sizing up a little if you want to get multiple years out of a younger racer's skis, although most coaches agree that skiing on a slightly shorter ski the second year is preferable to skiing on a ski that is too long.
  4. Coach's recommendations.

Description & Features

The Atomic Redster S9 FIS J-RP is a slalom ski for junior events with Atomic’s Junior Race Interface. This high-performance ski is fast, agile, and perfect for taking your slalom game to the next level. With Dura Cap Sidewall construction and Power Woodcore, you’ve got a reliable combo of torsional rigidity and edge grip on the piste. It also has Atomic's World Cup, athlete-proven full-width Ultra TI Powered laminate with updated double bonding for added stability, torsional rigidity, and edge grip. The narrow waist almost puts your turns on autopilot. The shovel, tail, radius, and increased V-shape create a unique geometry for juniors that makes handling super sharp. When every hundredth of a second count, the Redster S9 FIS J-RP can take you from just slapping plastic to attacking every slalom course with conviction and confidence.

Please Note: The Junior Race Plate (J-RP3) is compatible with a max ski boot sole length of 315mm.

Technical Info


The sidewall runs from base to top sheet for controlled power transmission and great edge grip. The rounded shape of the Dura Cap Sidewall picks up fewer dents and dings – a fantastic durability feature.


A combination of hard ash and light poplar that’s stable and sporty for our high performance skis.


A titanium layer above and below the core creates supreme shock absorption, strong running stability and a high torsional flex.
