The 3D wave-like XO-AirChannelDUCT™ construction on the outside of the shoulder, arm area and sides of the shirt, helps disperse the pressure from a backpack or jacket over a wider surface area. The inside ducts act like a bridge creating maximum air flow, allowing sweat to be effectively ventilated by thermal dynamics in warm or cold weather. During rest and recovery periods, the inside ducts trap warm air released by the body, providing a layer of insulation that helps reduce the risk of post chill after your activity.

The front, back and sides of the shirt have built in XO-AirFlowSPHERES™ that enhance climate control. They allow sweat to spread rapidly over a large surface area and with constant air flow they help keep the body cooler for quick and effective venting. The constant air flow movement draws moisture away from the skin, keeping the athlete very comfortable. During rest and recovery periods, the inside sphere's trap warm air released by the body providing a layer of insulation that helps reduce the risk of post chill after your activity.

The 3D XO-SHIELD™ system provides you with sweat traps and inner and outer air flow channels on the back. These provide maximum ventilation and insulation to keep you comfortable and performing better. During activity, a thin layer of sweat forms on the skin and any excess sweat is absorbed by the sweat traps. Sweat is evaporated by the inner and outer air flow channels for a controlled and effective cooling. During rest and recovery periods, the inner air channel pockets trap warm air released by the body. They provide a layer of insulation that helps reduce the risk of post chill after your activity.

During rest and recovery periods, the inside sphere's trap warm air released by the body providing a layer of insulation that helps reduce the risk of post chill after your activity.

The front, back and sides of the shirt have built in XO-AirFlowSPHERES™ that enhance climate control. They allow sweat to spread rapidly over a large surface area and with constant air flow they help keep the body cooler for quick and effective venting. The constant air flow movement draws moisture away from the skin, keeping the athlete very comfortable. During rest and recovery periods, the inside sphere's trap warm air released by the body providing a layer of insulation that helps reduce the risk of post chill after your activity.

The 3D XO-HVAC System™ provides sweat traps under the arm allowing for sweat to be quickly drawn away from the skin to the surface for fast evaporation. The unique ventilation and circulation ducts under the arm carry excess moisture away from the skin and allow for fresh air to be exchanged quickly, enhancing thermal dynamics.
