    Comfortable Fit

    Great fit. Not bulky feeling at all. I measure my waist at 36” but wear a size 34” waist pant. Glad I went for the size large as I wasn’t sure. They feel a little snug, but that is OK as I’m sure they will loosen up with washes. I intend to only hand wash them as well. I will try the longer leg ones for my next order.

    Nice Fit

    I really like the fit of these trunks. The fabric is nice and I like how the crotch is made. Sadly for me, they don't hold up well for my leakage. I can get up to 2 hours before a change is needed. But, they were honest about the capacity. Knowing this, I'm tempted to buy some of the other colors.

    Great Product

    Comfortable and attractive fit and the keep-dry technology works great! I purchased L, but wish I could have tried XL to see if a better fit. Maybe next time ?

    Men's no lead underwear

    I bought 5 pairs of the 3 inch weeks ago and they have been so great I decided to buy 3 pairs of the 5 inch ones.

    All are very comfortable and I've had no embarrassing leaks.

    Like - don’t love

    I prefer trunks and was interested in the features. The first thing that drew me to these was that there is no logo on the waist band. I hate those. I also liked the gray color option. Having worn them on two days away from home in warm weather I did feel they were a bit heavy especially because of the pouch and I felt a bit too restricted compared to what I usually wear. I’m average sized so it’s not that, more pouch could fix the problem. However I do like the protection offered, I’m 70 and while I don’t suffer from leakage that time may not be far off and these provide insurance against embarrassing spots.
