Looking for underwear during your time of the month? Enter THINX. Depending on your flow, its undies can either replace single-use pads and tampons (hello, eco-friendly points) or act as a back-up for that just-in-case protection. Here on ASOS, we’ve got styles that look and feel like regular briefs, made with the brand’s signature four-layer technology – we’re talking super-absorbent fabric and odour-fighting lining – anything for period peace of mind, right?
