Weight range: 8 to 40 lbs Age Range: 0 to 36 months Thirsties One Size All in One reusable diaper truly challenges the convenience and trim fit of a disposable diaper. This diaper offers absorbency, waterproof protection, and adjustability all rolled up into a stylish, comfortable and extremely effective cloth diaper. A built-in, three-layer microfiber terry soaker absorbs an amazing seven times its weight in liquid. The soaker is topped with our stay-dry microfleece which keeps your baby feeling dry. An additional layer of terry lies between the microfleece and TPU body of the diaper providing a last line of defense. The soaker is sewn in on one side (at the top of the diaper), which makes adding extra absorbent layers a cinch and tremendously decreases drying time...it’s the fastest drying diaper we’ve ever created! Closure in Snap or Hook and Loop Made in the USA.
