For a super lighweight top that has maximum breathability and allows freedom of movement for a wide range of activities then the Beta Tank is ideal. Perfectly suited to warm weather and more intense activities. 

Marmot says:

On an early morning climb, hike, or run, and the heat’s already making it hard going? That’s when the lightweight Women’s Beta Tank Top comes in handy. Quick-drying, moisture-wicking AirExchange fabric offers exceptional breathability and keeps you comfortable even if you break out in a sweat. Its sleeveless style won’t weigh you down or interfere with mobility, and the mesh racerback detail blends in with your sports bra.

Marmot's Womens Beta Tank is a super lightweight design that uses the AirExchange fabric, allowing increased ventilation, giving you a more breathable and comfortable tank top. This top is perfect for hot weather and outdoor activities where you'll heat up. The fabric has a good amount of stretch for free movement, has some UPF protection for sunny days, it wicks moisture well and dries quickly so it can keep you going for longer without becoming uncomfortable. The tank design allows maximum breathability and range of movement on top of what the fabric does and the inclusion of the racerback style is a welcome touch.  

As with many Marmot items this top is manufactured with bluesign approved fabrics to minimise negative environmental impacts from textile production.
