Adidas Neck Warmer Size Guide

This size guide covers the Adidas Neck Warmer, available in three sizes — One Size (OSFM), Small (S) and Large (L). Sizing is based on head circumference, measured just above the eyebrows. Most Adidas performance snoods feature a paracord and toggle adjuster at the back, allowing the fit to be fine-tuned after selecting your size. The high-stretch poly-spandex fabric blend also allows the neck warmer to be worn multiple ways — as a neck warmer, pulled up as a face mask, or worn slouchy around the ears as a winter headband.

How to Measure
  • 1
    Head Circumference Measure the circumference of your head just above your eyebrows using a soft tape measure, keeping the tape level and snug all the way around.

If between sizes, consider the fitting type: One Size (OSFM) has an adjustable toggle for fine-tuning, S is suited to smaller heads, and L provides a more generous fit.

Sizing Table — Adidas Neck Warmer

Large (L) 58–62 cm Generous fit for larger head circumferences

Head circumference is measured just above the eyebrows. One Size (OSFM) covers the widest range and features an adjustable toggle for fine-tuning. S and L are fixed-size options for those outside the standard range.

Fit Notes — Adidas Neck Warmer
  • Size based on head circumference measured just above the eyebrows. This is the point where the neck warmer sits when pulled up over the face or worn as a headband.
  • One Size (OSFM) covers the widest range (53–61 cm / 21–24") and features a paracord and toggle adjuster at the back. If the neck warmer feels slightly loose around the lower face, cinch the drawcord to seal out drafts and keep it in place during high-intensity runs.
  • Small (S) provides a snugger fit and is ideal for smaller heads or younger wearers with a circumference of 52–54 cm / 20.5–21.5".
  • Large (L) provides a more generous fit for larger head circumferences of 58–62 cm / 22.8–24.5".
  • The high-stretch poly-spandex fabric allows the neck warmer to be worn multiple ways — as a neck warmer, pulled up as a face mask against the cold, or worn slouchy around the ears as a winter headband.

Frequently Asked Questions — Adidas Neck Warmer

Measure around your head just above your eyebrows using a soft tape measure and match your measurement to the size table above. Most people will fit One Size (OSFM), which covers 53–61 cm and has an adjustable toggle for fine-tuning. S is suited to smaller heads (52–54 cm) and L to larger head circumferences (58–62 cm).

OSFM stands for One Size Fits Most. The Adidas Neck Warmer OSFM size is designed to fit a wide range of adult head circumferences (53–61 cm / 21–24") thanks to the high-stretch fabric and the integrated paracord and toggle adjuster which allows the fit to be cinched for a more secure seal.

Most Adidas performance snoods feature a paracord and toggle at the back of the neck warmer. If the garment feels slightly loose around the lower face during activity, pull the paracord ends through the toggle to cinch the opening smaller. This seals out cold air and prevents the neck warmer from slipping during high-intensity runs.

The high-stretch poly-spandex fabric allows the neck warmer to be worn in multiple configurations — as a traditional neck warmer sitting around the neck, pulled up over the nose and mouth as a face mask in very cold conditions, or worn loosely around the head with the fabric sitting over the ears as a winter headband.

Yes. The Adidas Neck Warmer is designed for running and high-intensity outdoor activity. The adjustable toggle helps keep it secure during movement, and the lightweight, stretchy fabric does not restrict breathing or neck movement during running. It is also suitable for cycling, walking, and general outdoor use in cold conditions.

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 stretch and shape of the fabric over time.
