Thinx for All Hi-Waist Period Underwear 2-Pack - Holds 12 Tampons

Our review of the Thinx for All Hi-Waist Period Underwear focuses on people who want a reusable, higher-rise brief that replaces or backs up disposable products. The bottom line: these briefs are best for those who prioritize strong absorbency and a dry, odor-controlled feel throughout the day; the standout feature is the super-absorbent core that the brand says can hold up to 12 regular tampons' worth of flow, making them a solid choice for moderate to heavy days or as overnight protection. They are comfortable enough for everyday wear but run high on the waist compared with some shoppers' preferences.

Key Features

• All-day absorbency: The super-absorbent core is designed to hold up to 12 regular tampons' worth of flow, reducing the need for frequent changes.
• Leakproof design: Built-in LeakSafe barriers help prevent leaks for up to 12 hours, giving reliable protection during busy days.
• Moisture wicking: Fabric is engineered to keep you feeling fresh and dry while helping to control odor throughout wear.
• Reusable construction: These briefs are washable and reusable so they offer a sustainable alternative to disposable pads and tampons.
• FSA / HSA eligible: The product qualifies for FSA and HSA reimbursement as a feminine care item, which can offset the upfront cost.

Who It's For
