What equipment a girl needs depends very much on their age and what their coach desires they have. For example, many of our older girls will have their own bats and other gear, where our t-ballers and 8U players probably won't. A few things to be aware of:
Each player must have her own glove. We highly recommend gloves that are leather, not vinyl, as leather is more durable and better for fielding.
Each player must have her own NOCSAE approved batting helmet. USA Softball rules also require that helmets have a NOCSAE approved facemask affixed, as well.
Players should have their own cleats. Softball, baseball or soccer cleats are acceptable. No metal spikes (except 14U).
SDYS does provide age appropriate bats for T-Ball and 8U players, so they do not have to have their own. Older players who do not have their own bats typically can borrow one from a coach or a teammate. Approved bats can be found on the USA Softball Certified USA Softball Equipment webpage and will have an ASA Certification mark.
SDYS highly recommends fielding masks for all players 8U and older, especially pitchers and infielders.
SDYS recommends padded sliding shorts for 10U and older players.
Softball pants are provided for the Spring season, but should be provided for the Fall season.
The most common "parent purchased" equipment problem we see is that the bats or gloves the girls come out with are too big. Check with your sporting goods professional or a board member if you need some assistance, especially with bats, so that we don't ask them to save that shiny new bat for next season when they are a little bigger and stronger to handle it.
