What to Compare Before Buying
- Head measurement: Compare your measurement with the relevant stated range rather than relying only on the one-size-fits-most wording.
- Ponytail position: The opening is low, so it is not suitable for a high ponytail.
- Helmet fit: If you plan to wear the cap under a helmet, check the fit with the exact helmet and gear you intend to use.
Compatibility, Size and Fit
The cap is described as elastic and suitable for most head shapes, but the stated ranges differ for men and women. Check which range applies to the cap you are considering. The description mentions wearing it under a bicycle helmet or ski gear; this does not establish fit with every helmet or item of gear.
Before You Decide
Check your head measurement against the relevant range, consider whether the low ponytail opening suits your hairstyle, and confirm the fit beneath any helmet or gear you plan to wear.
