Arm Guard Fit & Sizing Guide

Arm guards protect the forearms from gate impact and are an essential piece of ski racing safety equipment. A proper fit improves comfort, coverage, and confidence during training and competition. While most commonly used in slalom, many advanced racers also wear arm guards in giant slalom.

How to Size Arm Guards

Most ski racing arm guards are offered in two general size ranges: Junior and Adult. Sizing is usually based on forearm length rather than precise age or height. Brand measurements can vary, but junior arm guards are commonly shorter for younger racers, while adult arm guards provide longer coverage for larger junior, FIS, Masters, and adult racers.

To measure, bend the arm slightly and measure from the wrist to just past the elbow. The arm guard should cover the forearm without extending into the glove cuff.

General Arm Guard Size Recommendations

Arm Guard Size Common Length Range Recommended For
Junior 9–11 in / 23–28 cm Most younger junior racers, typically U8–U14
Adult 11–13.5 in / 28–34 cm Larger juniors, U16, FIS, Masters, and adult racers
Race Place Tip: If a racer falls between sizes, we generally recommend sizing up. Most ski racing arm guards can be trimmed to length using a fine-tooth saw or rotary cutting tool. This allows racers to achieve full forearm coverage while customizing the length to avoid interference with the wrist, glove cuff, or pole grip.

How Arm Guards Should Fit

A properly fitted arm guard should stay securely in place throughout training and racing while allowing complete freedom of movement. The guard should sit comfortably against the forearm without excessive pressure, gaps, or rotation.

  • Coverage should extend from the elbow toward the wrist.
  • The elbow should move freely.
  • The wrist should remain unrestricted when gripping ski poles.
  • The guard should not interfere with glove cuffs or pole straps.
  • Straps should hold the guard securely without cutting off circulation.
  • The guard should not rotate or slide during gate contact.

Common Arm Guard Fit Mistakes

  • Choosing a guard that is too long and interferes with wrist movement or glove fit.
  • Using loose straps that allow the guard to rotate during gate contact.
  • Selecting a guard that leaves too much of the forearm exposed.
  • Overtightening straps, causing discomfort or restricted circulation.
  • Keeping a junior guard after the racer has outgrown the coverage area.

Race Place Fit Notes

  • Arm guards are most common in slalom, where racers regularly cross-block gates.
  • Many high-level U16, FIS, collegiate, Masters, and adult racers also wear arm guards in giant slalom for added protection from gate contact.
  • Most plastic race arm guards can be cut to length, making it easier to customize fit when a racer falls between junior and adult sizes.
  • Many racers wear arm guards over a speed suit or training layer.
  • Fit preferences vary, but coverage and stability are more important than maximum length.
  • Replace arm guards if cracks, broken straps, or excessive wear reduce protection.
