Square fit only uses the best stretch fabrics available featuring Supplex and Lycra from Dupont. Allfabrics are treated with SWetOut™ a new and revolutionary Moisture Control Technology. Fabrics can also stretch up to 40% in size, so the numbers are approximated and will fit these measurements with a little bit more or less compression. We are moving out all stock and hope to have new styles soon. Please note that all sales are final and only store credit is available for returns.
