    So far, So good!

    I was never full-on incontinent and at 7 weeks post surgery was lucky enough to be dealing only with minor dribbles and sneaky leaks. I started using the EverDry boxer briefs and couldn’t be happier. They are comfortable, have zero odor and contain my leaks 100%.

    MNTD X Knix EverDry Cotton Boxer Brief 5"

    they feel great just fit a little tight (2XL) a 3XL would likely be a better fit for me.

    Comfortable, but more absorption than needed.

    These are the high absorption version which is more than I needed, but the medium absorption was out of stock and you have to get on a wait list for those. I wanted to try them out now however because I was really tired of using the pads. I went with the heavy vs. the light absorption version because I didn't think the light was enough protection for me personally. These fit well (I'm a 34 waist and bought the large size), but because the absorbent pad is thicker it does cause it to be hotter down there than I would like. Still, I think they're way better than using the pads which also cause extra heat but also stick to areas they shouldn't. I did get on the wait list for the medium absorption version, and will give those a try once they're back in stock.

    Love this product , Love the exchange policy

    Thank you so much for the awesome product. My Adult special-needs son really likes them.. I also had a screwup in ordering and missed changing the size on one of underwear in my order. Your exchange policy is so fantastic and I thank you so very much for that. So does Aaron.

    Great ginch, great price.

    Great price for a superior pair of underwear. Post prostate surgery, these have allowed me to feel more natural and enjoy regular activities without bulky pads or diapers. I also can sleep all night in them knowing that if there happen to be any small mishaps, it’s not going to leak out.

    It’s nice to know that a Canadian Brand supports Canadians and produces such a good product and a fantastic price. Compared to the cost of pads or diapers, these will last a long time and are paid off in less than 25 wearings. I have 11 pair now for daytime and nighttime use, and will be buying more in the future so that I can make it through to the weekly laundry day.
