What’s the key to a good day? A good night’s sleep! And what’s a must-have in your period underwear collection? A reliable sleep model! With a four out of five drop absorbency, it offers reliable protection on heavy flow days.
This new model is made from natural fabric and features a completely unique, innovative absorbent layer SAYUpro, developed in collaboration with the Technical University of Liberec. The functional layer channels liquid lengthwise, which improves absorbency while keeping the pad pleasantly soft and comfortable.
LENZING™ Modal is a natural material that is more environmentally friendly than cotton. Due to its softness and properties, it is also known as artificial silk. It is very light, airy and also wicks away sweat.
Due to the natural origin of the material, slight variance may occur in the fabric. They do not affect the function or durability of the panties.
The bands will shrink slightly after washing, so take this into account when trying on new, unwashed panties. When choosing the size we recommend to follow the measurements in our size chart, in case of any doubts please contact us via the contact form.
We've improved the classic cut based on your requests: the more sculpted panties, edged with softer bands, provide comfort even for wider thighs. The functional pad, with a touch layer made from the finest merino wool, is extended at the front for comfortable sleeping on stomach, while the back extends all the way to the top edge.
The cut is universal. You can wear it sitting on your hips, which will be appreciated by women who prefer a lower waistband. A classic fit will then suit those who prefer medium-high waist underwear.
