Boon Nursh Silicone Pouch Bottle
Silicone is a primary contact surface here — your food is in direct contact with it, not just a seal.
An air-free bottle where the milk only ever touches a food-grade silicone pouch and silicone nipple - the plastic shell it clips into never reaches the drink.
The verdict: Silicone only
The Nursh is built around a collapsible platinum food-grade silicone pouch that holds the milk, topped with a silicone nipple. The rigid outer shell the pouch sits inside is polypropylene, but by design the milk never touches it - only the silicone pouch and nipple. So the drink-contact path is entirely silicone, with the plastic kept out of the milk: a silicone-only rating. The trade-off is that this is silicone rather than glass or steel, and the soft pouch is a distinctive (love-it-or-not) feeding format.

Boon's Nursh replaces the rigid bottle wall with a soft, collapsible silicone pouch that sits inside a polypropylene shell. As the baby drinks, the pouch collapses instead of drawing in air, which is Boon's take on anti-colic feeding. Lightweight and shatterproof rather than glass or steel, it's a distinctive (love-it-or-not) feeding format that not every baby or parent takes to.
Pros
- Collapsible pouch is an air-free, anti-colic feeding design
- Lightweight and shatterproof, unlike glass
- Boon clearly documents the food-contact breakdown
Cons
- Silicone rather than a natural material or steel
- The pouch/shell format is distinctive and not every baby or parent takes to it
- Replacement silicone pouches are an ongoing cost
Notes
- Sizes: 4oz and 8oz; replacement silicone pouches sold separately
- Confirm you're using the silicone pouch, not feeding from the shell
