Great for Sensitive Skin
Size: Size 5, Unit Count: 128
I've tried other diapers and I keep coming back to Huggies as they are the only ones that don't cause irritation for my little one. Little one is 12kg and we use size 5. They are very roomy but still snug enough around the waist. I'm amazed at how absorbent and soft they are. Although there are "cheaper" diapers out there, they don't hold as much and aren't as comfortable.

Good, but not better than Pampers 360.
Size: Size 5, Unit Count: 100, Size: Size 5, Unit Count: 100
We use Pampers 360’s for our 18 month old, but we decided to try out Huggies 360’s to check if they were better
Huggies 360 differ from Pampers 360 in size. These Huggies are huge compared to Pampers, they fit true to size but are puffy and take up more space in the diaper bag and the diaper drawer.
My toddler prefers to run around wearing only a diaper. Huggies are less durable than Pampers, they will fray and pill more with the friction of surfaces.
They perform the same as the Pampers, we didn’t experience any leaks. They are also similar is softness to Pampers.
The elastic at the sides also seems tighter than Pampers.
The main reason we won’t be switching to Huggies 360 is that the absorbent panel in the front is wider and less flexible so more difficult to get into a comfortable position for my son’s anatomy.
They do function well as diapers, they just aren’t for us.

Good product overall
Size: 60 Count (Pack of 1)
Works really well, but only for a while. After about 3 or 4 weeks, it begins to stop working. Side effects-can leave you groggy if you don't get enough sleep. Helps you sleep better for a month or so. No odor. Good value for money, they don't cost a lot. Just melatonin and veggie caps. No other ingredients as far as I read

Works well I will continue buying them
Size: 60 Count (Pack of 1)
This melatonin gives me a good nights sleep. I thought it was 3 mg but it is not, my mistake! I take two of these because 3 mg doesn't do it for me. I sleep like a baby when I take these and wake up feeling rested.
