Style: High rise shorts with a medium length leg. Leak proof absorbency coverage from the front waistband to the back.

Facts: We do not use animal derived fabrics like Merino wool or crude oil derived synthetics like Microfiber, Nylon, Polyester or Polar fleece in our absorbency cores as these fabrics are associated to cause poor odour and rashes. 


Vitals are machine washable and can only be used in a dryer at low temperatures. Using a laundry bag when washing or drying in machines extends Vitals life further.

Step 1 - Rinse after use with cold water until water runs clear. The best time to change and rinse used pairs is in the shower.

Step 2 - You can choose to hand wash or machine wash your rinsed undies: Hand washing - wash immediately with a mild soap. Machine washing - pop rinsed period undies into a laundry mesh bag and machine wash at cold temperature.

Step 3 - Air dry later. 

Top Tip: On cold and wet days when air drying is not an option, you can dry washed undies on a heated towel rails or hang them by indirect heat. DO NOT use a fabric softeners, chemical bleach, iron or a tumble dryer at high temperatures (>40°C) as this can burn the leak proof layer and damage the natural fabrics of Vitals.

  1. Reduced waste: Vitals period underwear lasts 2-3 years, reducing 11,000 disposable menstrual products in a lifetime that take hundreds of years to decompose and end up in landfills, contributing to global waste crisis.
  2. Reduced carbon footprint: Vitals have a lower carbon footprint as they can be washed and reused for years, compared to the significant amounts of energy and resources required for disposable menstrual products.
  3. Reduced cost: A few pairs of reusable period underwear last for several years, resulting in significant cost savings in the long run, compared to the average person's annual expenditure on disposable menstrual products.
  4. Reduced exposure to harmful chemicals: Vitals are made from OEKO-TEX certified natural materials, reducing exposure to harmful chemicals such as chlorine, dioxin, and fragrances often found in disposable menstrual products that can be harmful to both the environment and our bodies.

Natural Materials
We choose unblended, pure natural fibres where we can. Our leakproof range consists of 100% natural absorbency gussets and 95% natural body contents. Our pure cotton range consists of 100% organic cotton and natural rubber derived from natural farming in South India. We do not use crude oil derived synthetic fabrics like nylon, polyester except for our trims which account to 5% of the total product volume and are offset with our synthetic neutrality scheme. All our fabrics are certified by OEKO TEX.
