Tranquillo is a German-based brand, using mostly organic cotton and EcoVero, in styles that always have comfort in mind. 

Tranquillo leggings are mid rise, and so soft!

Made of stretchy cotton jersey with an elastic waistband, they are a comfortable, snug fit.

Wear for chilling or being active - these work well as both loungewear or as bottoms with sweaters and shirts. 

Fit is true to size.
