<p>A garment such as a sport shirt (1) has concealed ventilation channels (2), which provide a continuous air channel between permanent openings. In one embodiment, the channels (2) are flexible and non-intrusive and the openings are maintained by springy eyelets (3). The eyelets (3) and channels (2) are attached to the main fabric of the garment (1), providing a robust and a streamlined construction. Another embodiment incorporates active ventilation structures (30) within the channels (2), the structures having a natural vibration frequency matched to a motion frequency spectrum of the wearer. In a further embodiment, the ventilation channels (2) are made of shape memory polymer and change shape in response to changes in temperature.</p> |
