    Great product

    These are a great product. They keep diapers secure against your body and smooth out the lines so they are less noticable. I used them when I had to wear diapers for medical issues. They also work great if you have alergies to metal belt buckles. I don't need diapers anymore, but still use them as an undershirt that does not untuck when I need to wear a belt. So my stomach does not break out. It's a great product for keeping diapers secure or just for an everyday undershirt.

    Aboslutely the best!

    Posted by James M on 2020 May 26th

    I just want to say I have been looking for a body onesie to keep my diapers in place. I have tried many, but these by far are the best I have used. I followed the size charts exactly and am so grateful to finally have a onesie I can wear out and about on a daily basis. Either as an undershirt or as a T-shirt. These are a great choice. Thank you for a solid product, I am ordering more of these tomorrow. I do wish there were more colors available, like: Blue or brown and I am sure pink purple yellow and red would also be popular. Thank you again.

    Very good product . Like that it stretches and fits me good . Holds diaper in place and keeps from sagging when wet . Dislike that snaps are located to low . They could be a couple inches higher in the front .

    Great Bodysuit for any need

    Posted by Blue on 2019 Nov 20th

    I absolutely love this bodysuit! Its comfortable, functional, and great for more than just diapers. I love that its black and not see through. Helps preserve dignity if you have to waer diapers 24/7. I'v personally delt with incontinence issues for nearly 4 years. This body suit really helped early on when having to go out in public. All rearz products are top notch. It also helps with allergic reactions to cheap metals found in most belts. I am very allergic to certain metals, so most belt buckles break the skin out on my belly. Even though my need for diapers has improved from 24/7 to just at night, I still wear the black bodysuits when I have to wear a belt. So these are great for more than just incontinence needs. I highly recommend them.
