Looking for headstrap for insta360 ace pro 2

Was doing some research into a headband for my insta360 ace pro 2. I want to create some sort of POV adventure/sport content for my friends and I. I like sports like spikeball and volleyball. I have heard that the official strap sold by insta360 is pretty flimsy. I am wondering if anyone knows any solid alternatives? I know the helmet mounts are pretty good but wearing a helmet while playing volleyball tends to be frowned upon.
