SKINS A200 Youth Short Sleeve Compression Tops use scientifically proven engineered gradient compression to help ensure efficient oxygen delivery to your muscles, which can enhance the power in your chest & upper arms, so you can take your opponents head on – even if they're in the year above you.SKINS also wrap & support key muscle groups to reduce vibration & focus the direction of the muscles while you're out on the sports field. They help to re-circulate blood lactate, so any pain experienced when you’re active will be reduced. Details in the A200 Youth Short Sleeve Compression Tops include a stretch mesh panel for underarm ventilation & shoulder panels positioned to maximise freedom of movement. SKINS also provide 50+ UV protection & moisture management in both hot & cool conditions.
