The Seven Zero Compression Youth Jersey was designed to give athletes unmatched energy-saving support with cooler body temperatures. Part of a two-piece jersey unit, it is meant to be worn under Seven's Zero Over-Jersey, which will give you unmatched performance. The athletic compression fit holds muscles tight to reduce unnecessary muscle movement or shaking that could result in energy loss. Muscle compression also promotes blood and oxygen flow, which aids in quicker muscle recovery, allowing for muscles to work at a higher rate for more extended periods. The ultralightweight, moisture-wicking performance material construction pulls moisture away from the body to keep you cool and dry. It offers an ergonomic design for resistance-free mobility and superior comfort.  Matching items are also available.
