My wife has just joined the Ump fraternity (she had to to see me ) and as she is very petite needs smaller gear .
Honigs caps are too big .
Any suggestions where smaller sizes can be purchased and of course freighted over here (New Zealand )
Also she just passed her qualifying tournament as did my 21 year old son this weekend .
Their first tournament and both of them loved it .
Their eyes were opened to its not all beer and socialising and they found it was damned hard work .

You might check the ASA national site. They sell plain (non-logoed) blue hats as well as the official ASA ones.
