UPS, save the underwear! This limited-edition series has a minor manufacturing variation: the gusset is slightly wider than our standard. However, this does not affect the quality or comfort, so we’ve decided to offer the underwear at a lower price of 42.50 €.
The natural LENZING™ Modal material and extended gusset provide a high level of comfort and a feeling of security (not only) while sleeping. The functional gusset, with a softest merino wool contact layer, is extended at the front for comfortable sleeping on your stomach, while at the back it reaches all the way to the edge. This means the underwear provides comfort and a feeling of security throughout the night, whether you sleep on your back, on your side, or frequently turn over in your sleep.
The SAYUpro functional layer, developed in collaboration with the Technical University of Liberec, directs fluid lengthwise, giving the gusset better absorbency while keeping it pleasantly soft.
The underwear is made from exceptionally soft natural LENZING™ Modal, which is lightweight, breathable, and gentle even on sensitive skin. It effectively wicks away sweat and, thanks to its softness, is sometimes referred to as artificial silk. Its softness and properties make the underwear extremely comfortable against the skin. Thanks to its closed-loop production process, its production is also more environmentally friendly than cotton.
Due to the natural origin of the material, minor variations may occur in the fabric. These have no effect on the functionality or durability of the underwear.
The elastic bands of the underwear shrink after washing, so please take this into account when trying on new, unwashed underwear. We recommend following the measurements in our size chart. If you are unsure, 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.
