For a smaller head, most caps are too big before they're anything else. The E-STRATA is Fractel's E-Series cap in blue & cream. A wider high-ponytail opening and quick-adjust rear cinch cord deliver a dialled fit on a smaller head, and PACE fabric keeps the build light and quick-drying through a hard session.
 
PACE fabric: a lightweight recycled-yarn knit that dries fast, so a soaked cap doesn't stay heavy for the rest of the run.
Pre-curved peak: sun protection with a low-profile, streamlined shape.
Wider high-ponytail opening with a quick-adjust rear cinch cord: sized for a smaller head, not just a smaller version of a bigger cap.
