Twist, invert, plank to your heart's content. The Sirsasana Headband will keep your bangs out of your face so you can concentrate on Downward Dog, not dripping sweat. Made of soft Merino wool, this headband is pretty enough to wear out of the studio. Also offered in Bold Prints. Simple and classic Merino headband. Finely tuned 18.5 micron New Zealand Merino at 195g/m2. Ibex designed this fabric from the need of a weight in-between their Woolies at 150g/m2 and their Zepher at 230g/m2. The weight of the fabric resembles that of a high quality t-shirt. It works well worn next to skin as a baselayer or on it's own. 100% Merino Wool.
