The First School Uniform That Includes Period underwear

The Period Uniform by Somos Martina is the first school uniform to include period underwear, so all Colombian students to attend school with comfort and dignity.

Any school uniform can become a period uniform by adding period underwear.

Challenging Stigma Through Uniforms

In Colombia, menstruation remains stigmatized, to the point that it’s not even discussed at home. As a result, many girls lack access to appropriate period products, causing them to regularly miss school. School uniforms are mandatory in Colombia and have long been used to promote equality and inclusion. The Period Uniform extends this principle to period care by adding period underwear to the official school uniform list.

The Best Option for Young Girls 

Period underwear is the best option for students and young girls because it is noninvasive, hypoallergenic, and feels like regular underwear. It provides up to twelve hours of protection without leaks or odors, keeping girls comfortable and confident at school. Reusable and durable, it is also the most affordable and sustainable choice over time, reducing monthly costs and waste while supporting better hygiene and focus.

Innovation That Comforts and Empowers

Somos Martina brings innovation to menstrual care with its reusable, sustainable period underwear, designed for comfort, protection, and affordability. The product’s triple-layer technology quickly absorbs moisture, locks in fluid, neutralizes odors, and prevents leaks while feeling just like regular underwear. Produced in Colombia under B Corp standards from organic, hypoallergenic, and vegan materials, each pair lasts up to three years, reducing waste, saving money, and supporting environmental responsibility and women's well-being.

Normalizing Periods, Avoiding Stigma

Instead of distributing period products through temporary, local programs that require separate logistics, the Period Uniform model builds on the existing school uniform system, making period care accessible by design. By including period underwear in the list of required school items, the initiative turns period care from an extra into the standard. As schools communicate these requirements to parents, the burden of initiating the conversation is lifted from the girls.

Works at Scale, Reduces Cost 

The Period Uniform initiative uses existing school uniform vendors and processes to distribute period underwear to students. Once established, this model works for every school without additional effort. For these participating schools, Somos Martina provides their period underwear ‘at cost’, resulting in a price comparable to regular underwear. This ensures that period protection is integrated into the uniform without becoming an extra financial burden.
