The Walgreens brand of disposable youth underpants for bedwetting are very similar to the Tyco brand of disposable underwear - they may even be from the same manufacturer. The sizes run S/M up to 65lbs and then L/XL from 70lbs and up (usually 125). Like GoodNites, they come in two different packages, one for girls and one for boys. The Small/Medium underpants come in a package of 17, and the Large/Extra Large bedwetting pants are in a jumbo pack of 13.
The package of the underpants describe them as "underwear for overnight protection. Some of the points mentioned on the package are:
The Walgreens bedwetting underpants, or Sleep Pants, run very large - the L/XL size can easily fit a child or adult up to 200 lbs. The absorbant pad is relatively large (the inside of the pant has a blue liner), and the sides are extremely stretchy. Unlike many of the cheaper bedwetting products on the market, the padding in the front comes up fairly high , which is benefits boys.
If you are looking for a cost-effective bedwetting underpant, Walgreens Sleep Pants may be what you are looking for. At $9 a package, they are a great alternative to GoodNites, and they fit well.
The first picture below shows the boys packaging. The next photo shows the bedwetting underpant, and the third shows the Walgreens Sleep Pants brief compared to the latest GoodNites disposable underpant.

For a complete bed-wetting solution, we strongly recommend the use of a Malem bed-wetting alarm for night-time training.
