No worries about leaks

I used the underwear on my heaviest flow day for a full work day and was never worried about leaks.

Love how absorbent it is - just wish the gusset was longer

What I love:

- these feel like and looks like normal underwear!

- very comfortable

- super absorbent

How these could’ve been better:

- I wish this had a longer gusset. Because it doesn’t I’m hesitant to wear this at night or on my super heavy days

Knix: please make these with a longer gusset. Only then will this be the most perfect period underwear ever!
