FAQ: Ultimate™ Midi Brief

Midi brief period pants with super heavy absorbency that hold up to 60 ml. High gusset for full coverage, slim 3 mm pad, soft breathable TENCEL Modal, and up to 12 hours of protection.

How much do the Ultimate™ Midi Brief Super Heavy pants hold?
They hold up to 60 ml of flow, about 12 tampons or 8 pads, which is our highest level of absorbency.
Do they fully replace pads and tampons on my heaviest days?
Yes, they are designed to completely replace pads and tampons on very heavy days and nights. If your flow is extreme, change sooner based on comfort.
Are they suitable for overnight wear, postpartum bleeding, or moderate bladder leaks?
Yes, they are ideal for overnight wear, postpartum bleeding, and moderate bladder leaks, providing up to 12 hours of protection depending on your flow.
Will they feel bulky, and how thick is the absorbent pad?
They are not bulky. The built-in absorbent pad is around 3 mm thin, so they feel soft and flexible while delivering maximum protection.
What are they made from and how do they feel against skin?
They are made with sustainable TENCEL Modal that is breathable and about 3.5 times softer than cotton, for a smooth, gentle feel.
How do I wash and care for them, and how long will they last?
Wash before first wear. After use, rinse in cold water until clear, then machine wash at 40°C without fabric conditioner and air dry. With proper care they are reusable for up to 2 years.

Utimate Midi Brief Super Heavy

Bought these for my daughter - she has never had the Ultimate pants before, but has been using the basics for 2 years and the teens. The fit is comfortable, however, the padding stops short at the back of the pants unlike the basics and does not go all the way up, so not the best for night time use. She was pleased with the comfort and the absorbency, but after just one wash, the elastic around the waistband on all 3 pairs has already frayed.
