"The added layer in the pouch of these underwear is perfect. Catches all the extra dribbles and keeps it from showing through on pants. Nice supportive fit that doesn't ride up."

    Great underwear with mild incontinence control

    I originally ordered the size L based on my pant size but found out I needed the XL based on my actual waist measurement. They were very easy to exchange and shipping was free! The boxers are very comfortable and give me confidence that I won’t leak out. Love them! Great company!

    Great fit, they work well

    I have been wearing pads for two years after prostate surgery. Incontinence was not that bad but enough that I wanted some protection. This product so far has worked well. I’ve had them only a couple of weeks but can say they are a good quality product. Just wish the price was a lower.

    They get the job done!

    Comfy, well-made, and useful - I thought I would try one pair to see how I liked them. Ordered 7 more pairs today.

    Great for Travel

    Great for travel. Thin enough to wash and dry overnight, therefore, no need to bring large number of underwear, saving space & weight.
