Designed to fit into your lifestyle, TOM Organic heavy flow period briefs look and feel like regular underwear. A tried and tested leak proof design, black in colour and with flat seaming for a seam free streamlined look. TOM Organic mid rise period underwear has been designed with a unique 4 layer leak free system that uses the natural properties of organic cotton fabric to wick away moisture, absorb menstrual fluid and protect against stains and leaks. This midi period briefs absorb up to three regular tampons' worth of fluid. Perfect to wear overnight, on heavy flow days or as back up layer of protection for a cup or tampon. At TOM Organic, people and the planet are their top priority; which is why they've been making world class organic pads and tampons, free from toxins and synthetics, since 2009. They created this reusable range so you can now have the freedom to choose the best period product to suit your lifestyle.

This reusable period brief is a mid-rise style which sits a couple of centimetres below your belly button, giving you the coverage and security you need when you have your period. Because the period brief is designed to prevent leakage, you may find they have a slightly “snug” fit compared to regular underwear, but TOM Organic soft elastic will keep you both comfy and dry. Based on feedback, TOM recommends sizing up to ensure the leg holes of the brief aren’t too tight (e.g. if you generally wear a size 12, it is recommended purchasing a size 14). Use th size chart for help in finding the right size for your period undies. Note that the hip is measured 20 cm below the waist (i.e. around the largest part of your bottom). The waist is measured around the base of your belly button. If you’re measuring between two sizes, we recommend choosing the larger size (e.g. if your waist is measuring for a size L, and your hips a size XL, purchase the XL). See image for measurements.
