What is Compression Clothing?
There are a few different technologies available in our Compression Clothing shop, but the basis behind them all is that muscles are designed to work in a linear fashion, up and down, left to right and so on. But, when we participate in sport, they move around a lot more through knocks and vibration, losing some energy in the process. Compression Clothing keeps the muscle in its best position to ensure more of the energy the muscle expells is in the right direction.
I dare say olympic swimsuits do it, I'm dubious whether Aldi gear does.
Still it might be a cheap base layer.
