new! league of our own collection

  • 4 YEAR OLD APPROVED!

    my son has recently become very picky when it comes to what he wears. he only wants to wear what he calls, “fast clothes"... I am desperate to find cute options that fit his comfort needs and this hit the spot!

  • OUR GO-TO OUTFIT!

    not only is courtside hands down the best athletic wear for boys we have ever bought, but it has become our go-to outfit for when we want an easy choice that looks polished and nice. my 4 year old loves it as well and always feels so cool wearing it, so it’s a win-win! courtside has our hearts forever and ever.

  • BEST FABRIC, FIT AND STYLE!

    can’t get enough of courtside! Our favorite articles of clothing that wash beautifully (thankfully, because we wear them more than anything else these days!).

birdies & aces collection

a message from our founder

our founder, fueled by the frustration of limited options for boys’ clothing with strong meaning, set out to make a difference. she understood that when you look strong, you feel strong, and you act strong. that’s why courtside kids offers a collection that combines meaningful designs with high-quality materials, allowing boys to express their inner champions and conquer the world with confidence.
