This is a review for the Walgreens Certainty diapers (officially known as Fitted Briefs), size medium. I purchased a 20 pack in November 2014.
Appearance, Size and Features
The diaper is plain white, with the only markings being two gold stripes down the center (the wetness indicator) which turn blue and fade when the diaper is wet, and a blue crosshatch pattern on the tapes. It has elastic leg cuffs but no standing leg gathers.
A stack of 3 diapers measured about 6.5 cm in height, so each diaper is about 2.2 cm (0.87 in) thick when folded. Not too thick to be noticeable in public, but still thick enough to make you feel nice and secure.
When outstretched, the diaper measures 29" (74 cm) in length, 21" (53 cm) in width at the wings, and 10" (25 cm) in width at the center. The length is this diaper's biggest issue in discretion, as it goes almost halfway up my back!
The diaper has velcro tapes, and they have a blue crosshatch pattern on them. You can readjust the tapes many times without them losing much strength.
The diaper has a cloth-like cover, so it is very quiet (almost silent under clothes). It still has a small crinkle which gets louder as it gets wetter.
The wings are made only of this cloth-like material, which worries me a bit for leakage issues, but I've yet to have any problems.
Performance and Fit
To test this diaper's capacity, I poured 100 mL of water into the front of the diaper I was wearing and then sat down for 30 seconds, repeating this process until it leaked. At the 800 mL mark, I noticed wetness beginning to gather around the edges. Small leaks formed between 1,000 mL and 1,400 mL. At 1,500 mL, the diaper leaked and I ended the test.
When wet, the diaper had swelled to about 4.5 cm (1.77 in), meaning it had about doubled in thickness. After I completed this test, I changed my diaper and wore the new one throughout my daily activities. I wet it normally and took it off after about 5 hours. It probably could have held more. The real test came that night when I wore one to bed. I had drank about 30 oz of liquid before I went to bed. I put the diaper on at around 10 PM and wet the diaper throughout the night. I woke up at about 4 AM needing to wet, so I stood up from bed to finish wetting and then waited a minute to let the diaper absorb. I then sat down on my bed and the diaper leaked, so I took it off (this was last night, I have two diapers ready for tonight so I can change if needed). The wetness indicator is actually a big help, and I would recommend changing once the whole indicator has turned blue, or shortly after. Even then, there is still padding left in the back if necessary. I would say that maximum capacity is about 850 mL (29 oz). The biggest issue with the diaper is clumping, which you can see if you open up the diaper after you've wet it. But, it isn't overly noticable when you are wearing the diaper. This diaper should also be able to hold a very large mess, but I've yet to do that in it.
Price and Final Thoughts
I bought a pack of 20 from Walgreens in November 2014 for $7.99. A 40 pack is also available for $16.99. That means that each diaper costs 40 cents. I think this is an amazing price for such a good diaper. It has great capacity, good tapes, okay leakguards and good odor control. It is thin enough to be discreet, yet thick enough to give you that wonderful secure feeling of a diaper. It isn't very crinkly at all, but the back is so high that it might be a problem for discretion (a onesie or a tucked in shirt could probably fix that though). I give it a 9/10 for amazing value and a surprisingly good product. I think this will become my go-to diaper.
