Phila 99ers / High School Varsity

As box lacrosse gains momentum in the US, Phila Box is powering the Phila 99ers, a full girls box program! The 99ers will focus on educating and serving players who want to improve their skills by playing a different version of lacrosse in the offseason while gaining the opportunity to learn from some of the best box lacrosse coaches in the world!


It's fast, it's physical, it's FUN!

Box lacrosse is played with a 30-second shot clock and smaller goals. You get far more touches and reps than in field lacrosse. These differences lead to better stick skills, creativity, quicker decision-making, and becoming the total lacrosse player. 

Expert coaching, an elite curriculum, and a best-in-class box experience is what you can expect with Phila Box. Our program is built around training while some are built around leagues or just game experience. In order to have success, you need ample training time to learn the proper techniques and strategy of the indoor game. Our mantra is we train more!


Player safety is something we take pride in at NXT. We provide athletic trainers at every practice as the game is faster and more physical than field lacrosse. We will gradually introduce equipment to the teams with the goal that by the end of the season, we are wearing full pads, helmets, and playing by official rules. Goalie equipment will be provided.

If you are interested in joining the team, register for a professional evaluation!

We look forward to providing a best-in-class box program this winter. 


Our high school team is perfect for the experienced field player ready to transition into the rink; or someone with prior box experience looking to take their game to the next level. The teams will attend 10 training sessions and 3-4 events.

  • 10 Training sessions at Steelyard Sports in King of Prussia, PA
  • Four tournaments: CT Box Championships (1/16), NXT Playday (1/29-PA), Dewlax Playday (2/11-NJ), Legacy Playday (2/18-Long Island)
  • Elite coaching from former NLL & Team USA coaches
  • Goalie coach
  • Phila Box jersey
  • You will play with “boys sticks” with deeper pockets, to enable more ball control on each touch.
  • A full value proposition and pricing will be available in conjunction with tryouts

Required Equipment 

"Boys" stick, helmet (included), gloves, chest protector, elbow pads, and mouthguard. Kidney pads are strongly recommended!
