FAQ: Ultimate™ Midi Brief - Heavy

Midi brief period pants in soft, sustainable Tencel Modal for heavy flow. Breathable, comfy and leak-locking for up to 12 hours of protection.

How much do the Ultimate™ Midi Brief Heavy pants hold?
They hold 20 ml or more of flow, about 4 tampons or 3 pads, which is ideal for heavy period days and light leaks.
Do they fully replace pads and tampons on heavy flow days?
Yes, on heavy flow days they are designed to replace pads and tampons. If your flow is very heavy, change sooner or consider a higher absorbency style.
What are they made from and how do they feel against skin?
They are made from breathable Tencel Modal that feels soft and smooth, with a built-in absorbent gusset and moisture barrier that lock in leaks and help control odour.
Can I wear them for up to 12 hours or overnight?
They provide up to 12 hours of protection. Suitable for daytime or overnight on heavy flow, change sooner if you start to feel wet since everyone’s flow is different.
How do I wash and care for them?
Wash before first wear. After use, rinse in cold water until clear, then machine wash at 40°C without fabric conditioner and air dry. Do not tumble dry or soak for long periods.
How long will they last and how many pairs do I need?
With proper care they are reusable for up to 2 years. Most people find 5 to 7 pairs work well for a full cycle.
