That's what I figured. The Blast shirt is one of the oldest shirts, it came out 15-17 years ago or something like that.
So get on with finding proper size for a F6 single ply.
My suggestion is that you call the guys at Titan, give them your measurements, and ask for a size suggestion.
Then get back with that to this board, and we'll be able to help you (usually the manufacturers suggests a few sizes larger than what is optimal for competing).
Yeah...titan will help you.
as you progress you can by a smaller shirt that is much tighter and it will help add more weight.
a couple pointers...
-Breathe to your stomach before lowering the bar.
-Simply control the bar on the way down, don't go too fast. let the bar follow the groove.
-Always have a lift off to keep your shoulders planted firm on the bench.
-Squeeze the bar with your hands as hard as you can and attempt to tear the bar in half on the way up. this actually helps quite a bit.
-Pause each rep at the bottom with the shirt on. have your spotter say "press" and "rack" just like in a meet.
-Focus on were the bar is going, don't just press, make sure it goes up in a straight line.
-Wear a small belt to keep the shirt from moving when you setup your arch.
-Always read the rulebook for the FED you are going to compete in, some are more technical.
Use these to help get the shirt on.

Good luck!
