Fox Size Guide

Fox is a leading manufacturer of high-performance cycling and motorsports apparel, protective gear, and accessories. With over 40 years of heritage, Fox specialises in MTB (mountain bike) clothing, helmets, body protection, and lifestyle wear designed for athletes who demand technical performance and durability. The brand is renowned for its scientific approach to fit, offering tailored sizing across multiple categories including mens, womens, and kids ranges. Fox products are engineered for serious riders, whether competing downhill or enjoying trail rides, combining style with technical innovation. Their sizing philosophy prioritises comfort during active use, with generous allowances for layering and movement.

How to Measure

To find your perfect Fox size, take accurate body measurements in light clothing (avoid bulky jumpers). For the most precise fit, measure in the evening when your body is fully expanded from the day's activity.

  1. Chest: Measure horizontally around the fullest part of your chest, keeping the tape measure parallel to the ground. Breathe naturally and don't pull the tape tight.
  2. Waist: Locate your natural waist (the narrowest part of your torso, typically above the hip bone). Measure horizontally without sucking in, keeping the tape measure snug but not constrictive.
  3. Hips: Measure around the fullest part of your hips and bottom, keeping the tape measure level and parallel to the ground.
  4. Arm Length: For cycling jerseys and jackets, measure from the centre back neck, across the shoulder, and down to your wrist with your arm slightly bent.
  5. Inseam: For bottoms, measure from the top of your inner thigh (where seams typically sit) down to your ankle bone or desired length.
  6. Glove Size: Measure the length of your hand from the tip of your middle finger to the wrist crease, or measure the circumference around your palm just below the knuckles.
  7. Helmet Size: Measure the circumference of your head at the widest point, approximately one inch above your eyebrows, using a soft measuring tape.
