The Vertx Long Sleeve Full Guard Performance Shirt is constructed from VaporCore™ technology to provide unmatched moisture and heat management no matter the environment. This long sleeve shirt features a semi-compression fit that comfortably skims the body without squeezing and a longline hem that stays tucked in during every activity level. The raglan sleeves, underarm gussets and 4-way stretch ensures maximum mobility and coverage while on the move. On top of that, this semi-compression shirt easily layers under low-profile or overt pieces to increase performance in the field. Built for the Prepared Professional™, the Full Guard Performance Shirt is more than the average base layer you can depend on in any condition.
