Meet Thinx Ultra-Soft Overnight Sleep-Shorts, a feminine solution designed for cozy confidence. The main fabric blends buttery-soft SUPIMA cotton with TENCEL Modal, delivering a gentle, breathable touch against the skin. This pairing aims to keep you comfortable from evening routines to late-night moments, so you can focus on what matters most.
Key fabric benefits
The Sleep-Shorts are designed for higher absorbency without bulk. They hold up to 12 regular tampons’ worth of flow, and the core can handle up to the equivalent of 3 regular pads. The built-in LeakSafe barrier aims to provide reliable protection for up to 12 hours, all while looking and feeling like regular underwear.
Performance highlights
In addition to protection, Thinx underwear focuses on staying fresh. The moisture-wicking design helps manage moisture and odor, contributing to a dry feel throughout the day or night. They can be worn as a total replacement for disposable period products or as a dependable backup to tampons or menstrual cups. The product is FSA/HSA-eligible, adding a practical dimension for budgeting period care.
Everyday benefits
Since 2013, Thinx has pursued sustainable solutions for menstruation and incontinence, aiming to foster comfort and community. This iteration emphasizes a cozy, inclusive fit and practical protection that suits real-life scenarios—whether you’re winding down with a book, commuting, or catching up on chores. Consider the Sleep-Shorts as a flexible part of your period wardrobe—an option that offers possibilities rather than guarantees, aligned with your rhythm and needs.
