    If you wear diapers away from home, a onesie is an indispensable part of your wardrobe, eradicating concerns about waistline diaper exposure. They also muffle crinkling and hold everything in place.

    Excellent quality and fabric

    These are the best. I highly recommend these. They do run large, I needed 1 size smaller than a normal t-shirt. Maybe 2 sizes as they stretch nicely.

    I’ve dealt with incontinence for over 6 years now. I start using cloth more and this really helps keep the diaper from sagging too much throughout the day

    Great Fit - Good Material - day or night

    Posted by Bob R on 2020 Jul 7th

    I usually shy away from any product that may have a child like appearance. But Reality sets in and necessity takes functionality is at the top of the list. If you wear diapers during the day, it is only a matter of time before that embarrassing moment hits you when you least expect it. Ve had my share of them over the years, and one of the most embarrassing moments was when I bent down to pick up my wallet I dropped while standing in line at the store. My diaper & plastic pants were in full view to everyone behind me in line. Whiteout going into details, I decided to start wearing a onesie to prevent a recurrence. I’ve tried them all. They are all similar in function, material, and looks. The most important thing to me is that the part of the onesie that is exposed looks like a standard T-Shirt and not something toddler-like. Most of the products available are good, nut the only one that fit all of my requirements was the REARZ’s Onesie. Great fit, good material, still looks good after many washings, and most importantly, it doesn’t have a toddler like looking neck. During the day, the look is number 1 Any thing that would make anyone give it a second look, is a “Hell No”. With that said, this is the best onesie is the best on the market. The extras are awesome fit and holds your diaper (cloth or Disposable) tight and vert comfortable. I also wear them at night (evert night) Just because I like them. You won’t go wrong with this Onesie. Bob
