Kurobaa Bamboo Fitteds OS

Try-It Tester Sale:

Yooki is trying out these diapers with the idea that we might carry them as a standard product in the future.

We're working with Kurobaa to offer a great deal on these bamboo fitteds so that you can try these awesome diapers made with premium materials at a rock-bottom low price.


Kurobaa One-Size Bamboo Fitted Cloth Diaper (shell, soaker and booster included)

Fits approx. 10-35 lbs

Don't let the epic softness of this diaper fool you. This one-size cloth diaper is designed to provide your child with the ultimate wetness protection but does require a diaper cover such as wool or a waterproof cover of your choice.


Terry & Heavy Velour (shell & soaker): 70% viscose from bamboo / 28% organic cotton / 2% poly

OBF Booster: 70% viscose from bamboo / 30% organic cotton).

ALL fabrics are Oeko-tex certified.

These diapers are made from natural materials and will shrink up a little after several washes (and even more so if you opt to regularly tumble dry...see suggested care instructions below).


Each diaper includes:


THREE LAYERS: 2 layers of natural/un-dyed HEAVY bamboo velour inside (against baby) and 1 layer of bamboo terry as the outer layer (two variants have custom dyed terry).

The small, envelope-style waist flaps provide a snug fit without adding excess bulk. Two rows of waist snaps are designed to eliminate "crotch droop" and leg gaps. The diaper shell also has one set of rise snaps to extend the functionality of the diaper... On the smaller rise setting, these diapers will work well for younger babies too!


Long tapered soaker is made of THREE LAYERS: 2 HEAVY bamboo velour layers and 1 bamboo terry layer. The length of the soaker can be custom folded to suit the absorbency needs of the child.


And the best part? This diaper comes with a bonus 3-layer OBF booster. Use the booster to extend wear time during the day, or to use overnight.


Choose from 6 colors:
LOTUS (magenta outer, natural inner, white snaps)
MALIBU (turquoise outer, natural inner, white snaps)
WINTERMINT (white with dark green thread, teal snaps)
GRAPEFRUIT (white with pink thread, goldenrod snaps)
SOURBERRY (white with blue thread, lime green snaps)
SUGARPLUM (white with dark violet thread, light purple snaps) 


When using brand new, natural fiber diapers, it takes 4-5 washes for the fabric to begin reaching peak absorbency because the natural oils in the fibers need to be removed. We recommend warm to hot water washes with detergent to aid in the removal of the natural oils from fabrics. You can start to use them after one wash, but keep in mind, they will continue to increase in absorbency until you've washed them about 10 times.

Standard Care

We recommend limiting loads to approximately 15 OS diapers at a time in most standard washing machines to allow enough space for agitation and proper cleaning/rinsing of the diapers.

1. Run a prewash on regular cycle with no detergent to remove as urine salts and as much solid waste as possible. Cold water works just fine for this.

2. Run a heavy-duty wash on cold or warm water with detergent (we recommend against hot water to help extend the life of the elastics on fitteds diapers- hot water is okay for soakers/boosters/flats/wipes). Water temp and detergent needs will differ depending on water type and your washing machine. In general hard water supplies need more detergent. We recommend using 1 oz (2 Tbsp) Unicorn Beyond Clean per load in front load machines. To keep your diapers soft and fluffy, add a fabric softener that doesn't cause build-up and repelling issues. We recommend 1/2 to 1 oz of Unicorn Beyond Soft in every load or occasionally depending on your softening needs/preference.

3. Run an extra rinse cycle if necessary. For example, if you feel your rinse water from the first rinse is still producing bubbles or if you've had some issues with skin sensitivity after washing you may need this extra rinse depending on your water and machine type).

4. Hang Shells to dry to extend life of the elastics or tumble dry on low heat.

**These diapers are made with all natural fibers and do require a cover to be worn over them.
