Training Pants Done Right!

Our one‐size waterproof shell with removable stretchy side panels creates a comfortable fit, while the replaceable organic cotton pads let your little one learn by feeling wetness. Now your child can pull them up and down when it's time to go, or you can unsnap the side, making messy changes less messy.

Training on the Go?

Flip Disposable Inserts also work inside the Training Pant, so you can enjoy life on the go. Disposables can also be used in addition to the cotton pad to boost absorbency overnight.

First off, I am a HUGE BumGenius fan and have enough diapers for like 10 kids (snd I only have 1 so far), I have a serious problem. I think I would really LOVE the Flip Trainer if it fit my little guy. My 8 month old is potty training and taking his diapers on and off all day is a hassle since he is so wiggly. I'd love to be able to just pull them up and down, so I bought these but they are huge on him and if he pees, it'd come right out the side (he's about 17lbs, with very skinny legs). Cotton Babies, if you could please make a trainer for early potty users, that'd be amazing- it is something desperately needed in the EC community. In the meantime, we will stick to our BumGenius diapers and wait until he fits in the trainers!


We have been using these for about a year now. My son loves them! We use them during nap with a disposable liner and at night with a disposable liner and cotton pad. There hasn't been leaks so far. They seem to be pretty easy for him to pull up and down by himself. They only thing I wish, is that the liners stayed put a little better. They seems to bunch up in the middle or move around a little. They are a little bulky with the two inserts but my son doesn't seem to mind. Over all I would recommend these to anyone wanting to make the potty training transition!


I bought only the shell, because I diaper with the flip system and have almost 100 of those inserts not to mention some prefolds and flats. Everything seems to fit and work just fine inside the trainer shell. Even without the velcro everything stays in place ok. I bought this for my 7 year old daughter who still wets almost every night. She is just now becoming aware (after summer camp) that wearing a "diaper" at night is not cool. And I was long tired of pullups. Every training pant I tried either got disgusting, because the absorbent material was sewn to the waterproofing and grown up pee really gets it smelling foul, or was woefully inadequate when it came to absorbing and stopping leaks. I bought the lovelace pattern and she loved them. I bought the disposable inserts for her to take to camp and she is very relieved to have a "nighttime underwear" to take to camp. We've been using them a couple weeks. Note - we already don't allow liquids after dinner and she goes to the bathroom right before bed to minimize whatever mess may occur. So far - my flip microfiber inserts seem to do an ok job. Some nights I wish I had put a doubler in there, because some wetness has gotten on her pjs and sheet. But it is a small amount that can be easily managed. I have noticed that she seems to wet much less often. I don't know if the feel of it wakes her up or what. I haven't used the disposable one yet. My only complaint (which is really more of a beg) is that these BARELY fit her. PLEASE PLEASE make larger side panels Cottonbabies!! Otherwise I am going to have to brush up on my sewing skills, which aren't that good to begin with.


I have 3 covers and 10 inserts. The over all design is great and well constructed, except that you have to add the laundry taps on each time you have to wash them. Wish they were sewn into them so you don't loose them. These work great on my 3.5 yr old for bedtime. If he wets his insert at night then we just change out the insert and rinse the shell. Works great but we had to wait a while before they would work over night b/c the inserts don't absorb like a diaper would. If you have a heavy wetter you might need to add a insert. This is a great option if you don't want to buy expensive pull ups. These will last us for 3 kids so we are really saving money!


I admit, I used BG 4.0 and disposables before the Flip trainers; my success with Cotton Babies is what swayed me to order from them again. I was looking for a trainer that would work away from home and my little one treated disposable trainers like diapers. Initially, I would have rated Flip trainers 5 out 5, but yesterday, I noticed after washing them (and I follow directions exactly!) piling around the edges. I also wish the side panels matched the cover. However, the function of them is wonderful! I love the inserts (so soft against skin, no rash issues, and do not retain smells after washing- a problem I did have with microfiber inserts). I used these for when we're away from home and bedtime; no leaks or extra inserts needed for my little one. I just wish I had one or two more. Two is not enough! Four would be ideal.
