How Period Underwear Compares to Other Menstrual Products

Period Underwear vs Pads

Period underwear functions very similarly to pads in that both provide external protection worn in your underwear. The key difference is that period underwear is reusable, eliminating the waste and expense of disposable pads while offering comparable comfort and absorbency. For those who like the familiarity of pads but want a more sustainable option, period underwear is often the closest match. For skin safe, organic cotton cover pads check out Pixie Pads.

Period Underwear vs Tampons

Tampons are internal products that absorb menstrual flow and offer freedom of movement without visible bulk. However, some conventional tampons contain synthetic fibers, fragrances, and chemicals that may cause irritation or disrupt your natural balance. Period underwear, like Pixie’s, features a 100% organic cotton gusset and is free from harmful chemicals, making it a gentle, non-invasive option for those seeking comfort and safety. Both tampons and period underwear can be used alone or together depending on your flow and personal preference. Learn more about tampon safety from MD Anderson.

Period Underwear vs Menstrual Cups

Menstrual cups collect flow internally and are reusable, making them eco-friendly and cost-effective over time. They require some practice for insertion and cleaning but can hold more fluid, making them suitable for heavier flows or longer wear times. Period underwear provides external protection without insertion, which some people find easier and more comfortable. Many find using both together offers versatile protection.

Period Underwear vs Menstrual Discs

Menstrual discs are similar to cups but rest differently inside the vaginal canal and can offer leak protection during intercourse. Like cups, they require insertion and care. Period underwear can be worn alone for ease or paired with discs for added security, especially on heavy flow days or during physical activities. Your choice depends on comfort, lifestyle, and flow.
