Very soft, high quality pull ups, but quite expensive
Size: 3T-4T, Unit Count: 112
We really enjoy this brand of pull ups as they are the softest of all the pull ups and they have adjustable straps on each side of the pull up. Most brands just are pull ups with no bells and whistles, but these have Velcro straps on each side that allow you to adjust the size but more importantly for us, it allows us to change his pull up without having to take the pants fully off. This is really convenient when we’re in a hurry or out for the day. The absorbency is some of the best diapers I’ve ever used. I feel I’m a diaper connoisseur and have tried everything from expensive to cheaper generic brands and we continue to buy these because of the quality, the Velcro straps, and also because of the reduction in substances included in the product, which is quite important for us as my sons skin gets irritated easily. The one thing that’s a negative is that they are very expensive. Diapers in general are crazy expensive but these are more expensive than other brands. I usually buy these in bulk on Sam’s website but saw they were on sale and had a deal where you subscribe and get 25% off so I bought two big packs of 112 diapers and ended up spending around $82 for 224 diapers, which is a pretty good deal. I do wish they would sell these for cheaper and unfortunately don’t think I’ll be buying them from Amazon unless they have deals such as I described above. I do overall recommend them though as they are better than any other pull up brand we’ve ever used.

Gentle on skin, strong on progress
Size: 4T-5T, Unit Count: 60
These Pull-Ups are a win for both toddlers and tired parents. The Skin Essentials design feels ultra-soft and breathable—ideal for sensitive skin and long wear. I love that they’re dermatologist-approved and sized just right for 38–50 lbs, which adds comfort and confidence during potty training.
The cute prints add kid-friendly flair, and the sides are stretchy but easy for little hands to pull down themselves—big bonus for growing independence. With 60 pants per box, it’s a solid value for families going through this milestone, even with the slightly higher price tag.
At $39.09 and backed by Amazon’s Choice status and 4.7 stars across 600+ reviews, they’ve earned their spot in our routine. Bonus: over 1,000 purchases last month show we’re not the only ones loving them.
If you’re potty training and want gentle, effective help for sensitive skin, these Pull-Ups check all the boxes.

Soft and flexible
Size: 3T-4T, Unit Count: 16
My son suffers from sensitive skin and these new Pull-ups really reduce the red rash he gets on his hips from the diapering. They are easier for my son to pull up on his own. A high quality training diaper that doesn’t leak and is comfortable for hours.

Seem to run slightly larger
Size: 3T-4T, Unit Count: 112
These are cute and my son loves the Buzz picture on them. I buy multiple different pull ups, and these have been great however I do think they run slightly larger. The quality is great, we haven’t had any leaks, and my son loves to wear them. He can easily pull them up and down himself.

Soft and comfortable for sensitive skinned toddlers
Size: 2T-3T, Unit Count: 76
I’ve been using the Pull-Ups Boys' Skin Essentials Potty Training Pants for a few months now, and overall, they’ve been a great help during potty training. One of the best features is the velcro sides, which make on-the-go changes a breeze—especially when I need to leave my toddler’s shoes and pants on. It’s incredibly convenient and saves time.
The training pants are also very soft and comfortable, which is important for a toddler with sensitive skin. However, I did have to size up as my toddler quickly grew out of them. (wears a size 2t but he fits the 4t pullups better)
While these Pull-Ups have worked well for daytime use, I have experienced some issues with overnight leaking. This can be a bit of a hassle, so I’m still experimenting with different strategies to manage that. Overall, though, they’re a solid choice for potty training and are very comfortable for my toddler. Highly recommend for daytime use, though you might want to consider something else for overnight protection.
