All-Star Most Comfortable Spankies

Hey, I am wondering if someone can help me out. For my college team we have to buy our own spankies and the ones I have been wearing the past few years have been so uncomfortable. It's like the leg hole is too tight, and squeezes until I am almost bleeding. Mind you, they are a size adult medium and it's not even the size really that's causing them, it's more of the material. I am looking for a pair of spankies that are more stretchy than the ones I have now, more like a sports bra, because these have hardly any give to them.

Can anyone recommend a pair to me that you feel are incredibly comfortable and stretch with your body, instead of being binding? Thanks in advance!
