US’ Proof, the leading feminine wellness company in the US, has announced its official expansion into the teen aisle to help new menstruators feel comfortable, confident and protected against leaks all cycle long. The Proof Teen line offers reusable, sustainable, and affordable period undies in extended teen and tween sizes and new colours and styles.

Every pair of underwear in Proof's Teen line has the brand's signature triple-patented Leak-Loc technology built in for superior leak proof protection that's discreetly hidden in layers so thin, they feel like a regular pair of undies. Teens can live their life to the fullest feeling protected through long school days and busy after school activities; Proof Teen's moisture-wicking and antimicrobial fibres will keep them feeling dry, while helping to fight odours all day, the company said in a press release.

The new re-usable line of underwear also provides teens with a more sustainable solution to period care. With 20 billion pads and tampons ending up in North American landfills each year that take 800 years to decompose, making the switch to Proof's teen line is a no-brainer for the next generation of young women.

Proof's teen line comes with absorbencies that range from super light (holds up to one panty liner), to moderate (holds up to three regular tampons) to super heavy (holds up to five regular tampons) in three new colourways including aqua, purple and tie-dye, in addition to their classic black colourway.

“We are thrilled to unveil our line of sustainable teen underwear that offers adorable new styles and unbeatable protection to help make every girl's time of the month stress-free. Proof Teen has super-absorbent undies for every phase of her flow to make stain anxiety a thing of the past. From first periods at sleepovers to surprise spotting in band practice or heavy periods that start in the middle of Algebra, we've got her covered,” Jodi Caden, CEO and co-founder of Proof, said.
