Heavy (Medication Induced)
I am on blood thinners, which causes my period to be 100 times heavier. I've struggled for the past year to find products that can keep up and, most importantly, not leak. I can only wear a super absorbent tampon with a thin pad liner for 30 or less minutes at a time because my flow is so heavy. i had to resort to gigantic heavy flow pads with a tampon during the day and super super large thick pad with double panties overnight. Even with that, i leak. Not to mention the bulky discomfort of the pads At first, i was skeptical because these actually looked and felt like regular underwear. i couldn't wrap my brain around how on earth this underwear would hold so much liquid. I love these period underwear. it has answered my prayers!!! i dont need to worry anymore about being out and about and leaking. i even wore them out one night dancing on one of my heavy days! i really can't believe this. I've bought 2 more since and even got some for my sister who is struggling with incontinence after having her baby. They are awesome! Sizing is interesting. I saw 1 reviews regarding sizing being too small so I got an xl and it fits non snug. ( im normally a large) my sister is way bigger than me and she said the xl was just fine! i think the material stretches fine and gives in the right places without cutting off circulation or making you feel uncomfortable. im 150 my sister is 200 both of us tall

Very discreet, looks and acts like every day undergarment. For light urge/dribble/leak. No pads needed. Washable, not bulky, undetectable under clothing. These provided the protection I needed and gave me the confidence to go about my normal daily activities. Highly recommended

Grandma's helper - Amen
I have sudden urges and will “dribble” small amounts en route to commode. This underwear garment provides the absorption, protection, and privacy I want. They look like regular panties. I wear the same pair sunrise till bedtime. I previously used a pantyliner, which doesn't absorb, maybe changing once a day, I didn't like the dampness against my skin. I never experience any feel of moisture using these briefs, there's no bulky feeling, no odor. I have washed at least 15 times, air drying, and they look, feel, and perform like they're new just out of the box. Fit is perfect and don't lose their shape. Still do my Kegels, combined with wearing this garment, and I'm happy.
