Product Description

The ultimate comfort for your most sensitive days. Whether you’re managing a heavy period, postpartum recovery, or bladder leaks, the Super Leakproof® Dream Short™ offers a snug, supportive fit that stays in place all night. The high-rise waistband gently hugs your core, while the soft, breathable fabric ensures no-chafe comfort. Designed to replace bulky overnight pads, these period shorts offer a "no-bulk" solution for total peace of mind. Available in inclusive sizes XS to 4XL.

Comfort-First Fit

Boxer short style that hugs your body and stays in place as you sleep.

Worry-Free Protection

Designed with an extra-long liner and our patented 360 LeakSeal™, it helps lock in leaks from every angle, even if you toss and turn.

Heavy Absorbency

Absorbs 5.5 super tampons worth of liquid for overnight protection, heavy flow days, and light bladder leaks.

No-Show Style

Buttery-soft and smooth fabric gives a seamless look and feel. Disappears under clothes, even leggings.

    So far so good

    They fit PERFECTLY and are incredibly comfortable. The absorbent lining isn't the shape I was anticipating, but I have not had any problems so far.
