Yes. They are designed for overnight wear, heavy flow, and postpartum bleeding. Many users also find them a comfortable option during heavy nights related to PCOS. They provide up to 12 hours of protection, but change sooner if you start to feel wet since everyone’s flow is different.

Comfortable and confidence-boosting!

I love these. I got a couple of heavy overnight pants to keep me ‘safe’ overnight, as I’m so uncomfortable in pads. I have used washable pads for years now, but nighttimes I still feel uncomfortable. I’m very heavy the first few days of my period, and these make me feel much more confident that I am not going to leak. I decided to try wearing one when I had to attend a family occasion when very heavy, so wore a pair of overnight WUKA pants and went ALL day without any leaks. They were so much more comfortable than wearing and having to change pads every hour. WUKA pants are honestly such a life-changer. I have since invested in a set of daytime heavy pants. Thank you WUKA!

Wow, they don't leak - they're amazing

Just tried the overnight briefs and they were really comfy, I was really worried I was going to leak, I kept checking 😁, but nope all fine. I'll probably get some lighter pairs for during the day. I've got 3 over night pairs at the mo. They wash well, and do take time to dry, but I washed them in rotation.

Great knickers, struggled to dry them

Didn’t leak at all in the knickers but they took around four days to dry after I hand washed them. I ended up needing to place them on a heated rack to fully dry them which I know is not recommended but didn’t know what else to do
