    Super plus leakproof no show high rise

    Poor coverage across the bum. Feels like I'm getting a wedgie. I have purchased several other styles over the years and have been very happy and although I like the high protection in the front and back in this particular style, it's not a tight fit around the top of the leg and skimpy across the bum.

    No super leak proof

    Comfortable to wear BUT they are not very leak proof. I thought I could get away with thinner smaller pads, but apparently not.

    Great absorbency, but VERY different fit

    The Super Plus absorbency is excellent, and the front to back liner is a nice feature. It does make the underwear bulkier and heavier, though, so it gradually slides down. The fit is also quite different from the Moderate absorbency pair, even though they’re shown on the same page with the same size chart. In my photo, I’ve layered the two pairs (same size, same purchase date), and the Super Plus is clearly about an inch wider on each side and an inch shorter. Nowhere on the site is there any information about how high 'high rise' actually is, since both styles say they sit at your natural waist, and the coverage description isn’t enough to figure it out that the Super Plus sits lower.

    I have an apron belly and a flat butt, so I need a snug, high-rise fit. Because these aren’t as snug, the sides start leaking a little after a long day. To be fair, that’s very mild compared to how extreme my flow is. If you've always told yourself that you bleed more than the norm, I'm confirming these are for you, because that's my case too.

    However, all four of my new pairs are already slipping down under my belly during the night, after just two cycles. If you have a similar body shape, I’d recommend sizing down for a snugger fit. I’ve owned a few pairs from this brand before and they lasted 2 to 3 years, so I’m disappointed that these are already slipping so soon, especially at this price.

    Product is definitely heavy duty.

    But $44 is pretty steep for a pair of underwear so I will research other brands.

    Perfect protection

    I use them as added extra protection during a heavy menstrual cycle . They give reassurance without being to bulky and hot good support as well
