How to Choose Your Size
- Start with the chart that matches the product type: footwear, men’s apparel, women’s apparel, or youth apparel.
- Measure your body first, then compare your numbers to the chart instead of choosing only by your usual casual clothing size.
- For protective riding gear, consider the base layer or riding layer you plan to wear underneath.
- Check the product detail page for any fit notes, style-specific size guidance, or model-specific sizing information.
Measuring Tips
- Chest: Measure around the fullest part of the chest, keeping the tape level under the arms.
- Bust: Measure around the fullest part of the bust, keeping the tape horizontal.
- Waist: Measure around your natural waistline, near the navel.
- Hip: Measure around the fullest part of the hips, about 20 cm below the waistline.
- Inseam: Measure from the crotch down to the bottom of the leg.
- Height: Stand straight against a wall and measure from the floor to the top of the head.
Fit Notes and Between-Sizes Advice
If your measurements fall between two sizes, choose based on how you prefer the item to fit and how the product will be worn. For a closer performance fit, the smaller size may feel more secure. For added comfort, layering room, or a less restrictive feel, the larger size may be the better choice.
Boots, gloves, jackets, pants, suits, protectors, and casual apparel may fit differently by construction. Always review the product detail page before making your final size choice.
