A7 Center Pole Bar Grip Shirt Review for Squatting

I just bought an A7 bar grip shirt and I have to say it is a game changer for my squats. I have always had trouble with the bar sliding down my back especially when I am wearing a smooth gym shirt. The silicone grip on the back of the A7 shirt really locks the bar in place.

I train at a commercial gym where they do not allow chalk on the bars so this was the perfect solution for me. I am curious if anyone has used the long sleeve version and if it is too hot for summer training. I find that the grip stays tacky even after multiple washes which is a relief.

Are there any other brands that make similar grip shirts? I have seen some cheaper ones on Amazon but I am worried the quality won't be as good. If you have tried the A7 shirts let me know what you think about the sizing because I found mine to be quite tight in the shoulders.
