Engaging ColdGear technology within the UA Crew keeps the wearer warm whilst the compression element works to increase blood flow around key muscle areas. Implementing Under Armours’ proprietary warming technology, the Compression Crew makes best of ColdGear technology ensuring the wearer remains dully warm and dry. Through utilising an incredibly warm brushed fabric, the wearer is able to experience warmth generated from all extremities of the top. Add to that UAs’ signature moisture transport system and the top soon relieves the wearer of excess moisture. The 4-way stretch fabrication employed by UA allows the wearer to achieve an unencumbered range of motion. Whilst a flat-lock seam construction prevents potential irritation through defeating chafing, with anti-odour technology completing the piece, quelling the spread of odour-carrying bacteria.
