The Skinny

The Boon Nursh is one of our favorite bottles with a ventless system that creates an air-free feeding experience, helping to prevent colic. We like that everything on the inside of the bottle is silicone, so harmful chemicals never have a chance to make it into the food. With a plastic outer shell, the Nursh gets the added benefit of a stable base and increased durability overall (unlike other silicone bodies). With many positives and very few downsides, this bottle earned a Top Pick award and a high rank in our review.

Our Analysis and Test Results

Boon started off making bath toys for little tots, but that quickly expanded into making everyday products for children of all ages. They are known for their modern and minimalistic, yet fun designs and that style shines through in the Nursh bottle. The easy-to-use and straightforward silicone drop-in system is one of the best we've seen.

We appreciate any product that makes an effort to be highly functional and easy to use while still being good for baby's health and the environment. The Boon Nursh does all of the above and more. Similar to the Comotomo, the body of this bottle is silicone, but the plastic outer shell gives it a more stable base and increased protection from being squished, the main cause of leaks in the Comotomo. The vacuum created by the collapsible silicone liner eliminates the need for a vent but still keeps out any colic, causing air bubbles. The wide nipple mound is modeled to be very breast-like, and even though the nipple is a bit stiffer than average, we think the design may help avoid nipple collapse, which is more common in a ventless system.

The Nursh has a total of four parts (not counting the nipple cover), but for cleaning, there are only two pieces, the liner, and the nipple. This makes it one of the easiest bottles of the bunch to wash, and the wide mouth opening means you don't even need a bottle brush. The liner is flexible enough that you can also turn it inside out if your hand is too large to fit inside.

Unlike the Comotomo, the Nursh has no plastic parts on the inside. The silicone nipple seals with the silicone liner and creates a toxin-free environment for baby's milk. The pouch is freezer safe, and can be boiled, sterilized, and microwaved, making it a good contender for breastmilk storage when used with a flat cap.


In a ventless system like this, we understand the need for such thin and pliable silicone for the liner; unfortunately, this makes the silicone feel fragile and susceptible to tears. With normal use, and the addition of the plastic outer shell, this shouldn't be a big problem, but it is something to keep in mind when cleaning. In any case, the relatively inexpensive replacement pouches are available for purchase and may be a good idea to keep on hand.

The volume markings on this bottle are shiny numbers etched into the matte background of the plastic shell that corresponds to lines on the silicone pouch. There is very little contrast, and the markings can be hard to read, especially when the bottle is full.

We love the Boon Nursh and think it a cool addition to the more traditional baby bottles we've seen. Silicone offers the lighter weight and greater durability that you find in plastic combined with greater eco and health benefits of glass, making it a bottle that gives you the best of both worlds. The breastlike nipple and simple cleanup process make it a favorite of parents and children alike.
