Nike Neck Warmer Size Guide

This size guide covers the Nike Neck Warmer, available in three sizes — XXS/XS, S/M and L/XL. Sizing is based on head circumference, measured approximately 2 cm above the eyebrows at the point where the item will sit.

A Nike hat size reference is also included as a secondary guide.

How to Measure
  • 1
    Head Circumference Wrap a soft tape measure around your head approximately 2 cm above your eyebrows — this is the point where the neck warmer will sit. Keep the tape snug but not tight and note the measurement in cm or inches.

If on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.

Measurement XXS/XS S/M L/XL
Nike Hat Size 7–7 1/8 7 1/8–7 1/4 7 1/4–7 3/8
Head Circumference (cm) 56–57 cm 57–58 cm 58–59 cm

Head circumference is the primary sizing measurement. Nike hat size is a separate sizing scale used across Nike headwear and remains the same whether you are viewing cm or inches — the fractional values (7, 7 1/8 etc.) are not cm or inch measurements. Measure approximately 2 cm above your eyebrows. If between sizes, size down for a tighter fit or size up for a looser fit.

Fit Notes — Nike Neck Warmer
  • Size based on head circumference measured approximately 2 cm above the eyebrows. This is the point where the neck warmer sits on the head.
  • The Nike hat size row is a secondary reference only and uses Nike’s own hat size scale (7, 7 1/8, 7 1/4 etc.), which is separate from cm and inches. These fractional values are the same in both the cm and inches views — this is correct and not an error. Always use your head circumference to confirm the correct size.
  • If on the borderline between two sizes, size down for a tighter, more secure fit or size up for a looser, more comfortable fit depending on your preference.
  • The size ranges are close together (1 cm increments) — if your head circumference falls exactly on a boundary (e.g. 57 cm), personal fit preference determines which size to choose.

Frequently Asked Questions — Nike Neck Warmer

Measure around your head approximately 2 cm above your eyebrows using a soft tape measure. Match your head circumference to the size table above. If on the boundary between two sizes, choose the smaller size for a tighter fit or the larger for a looser fit.

Nike hat sizes are shown in the table as a secondary reference. They correspond to traditional hat sizing (7, 7 1/8, 7 1/4 etc.) which some customers may already know from other Nike headwear purchases. However, head circumference in cm or inches is the more reliable guide, as hat sizes can vary between brands.

Measure approximately 2 cm above your eyebrows, which is the point where the neck warmer will sit on your head. Keep the tape measure level all the way around and snug against the skin without compressing the hair. If you have thick hair, you may want to measure with your hair down as it would normally be worn.

The Nike Neck Warmer size ranges differ by just 1 cm per step. If your measurement falls clearly within one range, that size is the right choice. If you are right on the boundary, it comes down to personal preference — size down for a snugger fit that stays more securely in place, or size up for a more relaxed, comfortable feel during activity.

Nike Neck Warmers are designed to be worn around the neck for warmth during running and outdoor activity. Some styles can be pulled up over the lower face or worn around the head depending on the design. Check the specific product description for details on how each style can be worn.

Machine wash on a gentle cycle at 30°C. Do not tumble dry — allow to air dry naturally. Do not iron or dry-clean. Follow the care label on your specific product to preserve the fabric and fit over time.
