Thanks before start design your logo I did R&D regarding "Squash apparel" and understood about Squash related logos. both logos I did has the "S" letter from Squash. "when hitting the ball against the front wall and returns in speed" that's the concept behind, but also its con-way the speed/human/community aspect. the logo can be use it textiles/ dark/light backgrounds without any problem. I hope the concepts will be related to your business where it's mainly con-way the message of Squash/Speed/human/community touch etc.
