2XUElite MCS Compression Calf Guards

How do you clean these?

There ar not size chart, the sizes are the same than the regular user of 2XU? I'm small on the regular ones, thanks.

Do both sleeves have the logo on them, or is one black only and the logo only on the other sleeve?

Hi, there are better than 2xu compression calf guards (asin: b00591uo8s) ? they cost half of the price, thanks
