WHY YOU’LL LOVE IT

From the creators of the original Heavy Flow Period Pants, WUKA Stretch™ Super Period Pants are built for very heavy flow. They absorb up to 60ml of period blood - the equivalent of 12 tampons or 8 pads - giving you maximum protection, comfort, and confidence on your heaviest days.

HOW IT WORKS

Made with a double-layer inner gusset and CoolMax™ technology for ultra-fast wicking and quick drying. Stretch™ Technology flexes to fit across 4 sizes in one pair, while the high waist design adds comfort and coverage. Seamless construction ensures no VPL and a smooth, flattering fit under clothes.

BEST FOR

Very heavy flow days, long shifts, sleeping, or postpartum recovery when you need extra coverage and security. Provides up to 12 hours of leak-proof wear.

Leak proof but not as comfy as WUKA organics

Only 3* because I've had WUKA organics for years and have loved them. I thought I'd try these. They aren't as stretchy as they say considering they're supposed to fit large too. I am a size 10/12 normally. Today I am bloated and they're uncomfortable 😣 I can feel the restriction on my stomach and very aware of them when I'm not usually with the others. stupidly bought 5 pairs and now I wish I stuck with the organics.

No leaks though, I just loved the original organic period pants, comfy, stretchy and proper cotton. Will be purchasing them again and again
