Size & Fit

One size. Engineered to fit most.

Every BRIM Initiative cap is built on a single structured crown with an adjustable snapback closure, fitting head circumferences of 56–62 cm (22″–24.4″) — roughly US hat sizes 7 to 7 3/4. There is no size to choose. Choose the silhouette instead.

Flat brim · 6-panel

The Initiative

Crown height 4.75″ / 12.1 cm
Visor 2.75″ flat square
Stance Tall, full, bold

Sits high off the brow with a squared flat visor. The statement of the two.

The Vanguard

Crown height 4.25″ / 10.8 cm
Visor 2.7″ pre-curved
Stance Lower, classic

A familiar ballcap profile that sits just above the ears. The everyday of the two.

Both caps share the same head opening. The difference is crown height and visor shape — not circumference.

Fit range

Head circumference Inches US hat size
56–57 cm 22.0–22.4″ 7 – 7 1/8
58–59 cm 22.8–23.2″ 7 1/4 – 7 3/8
60–62 cm 23.6–24.4″ 7 1/2 – 7 3/4

Outside this range, the snapback will not close comfortably. If you measure 63 cm or above, reach out before ordering.

How to measure

  1. Wrap a soft tape around your head about a finger’s width above the ears, level across the forehead — where the cap will actually sit.
  2. Keep it snug, not tight. One finger should slide under the tape.
  3. No tape measure? Wrap a length of string, mark it, then lay it flat against a ruler.

Between two numbers? Round up. The snapback takes up the slack.
