ThinkFast Vent Tank

About this find

The ThinkFast Vent Tank from Outdoor Voices is made for workouts that make you sweat. Its breathable mesh back panel lets air in and supports free movement, and the ThinkFast Vent fabric is engineered with cooling technology to handle sweat. It is made for high-sweat recreation like running, training, spinning, and pickup games.

The fabric is sweat-wicking, quick-drying, and cooling. The fabric content is listed as 66% recycled polyester, 29% lyocell, and 5% elastane, and also as 70% polyester, 25% lyocell, and 5% elastane, so the blend can vary by version. The elastane adds stretch, and the relaxed fit keeps the tank from clinging. It works well on its own for a run, a gym circuit, or a spin class.

If you like a longer workout, pair it with lightweight shorts or joggers for an easy, breathable outfit. Because the mesh sits on the back, think about wearing it where that airflow matters most, like hot-weather training or indoor classes.

Care is simple. Machine wash cold and lay flat to dry. Do not bleach, iron, or dry clean it. Laying it flat to dry is the one step worth following every time, since it is the only drying method the care instructions allow.
