The small BPA-free wide-mouth bottle (160ml) is supplied with a very soft silicone teat in size S and cap. The bottle has also proven on the go so far has kept the bottle tightly. The bottle is very handy and compatible with Lansinoh breast pumps. The vacuum cleaner is much softer and more flexible than other silicone nipple, I know.
The only thing that bothers me personally on this bottle, the hissing noise generated while drinking. Although the valve with the so-called Air ventilation system reduces the swallowing of air, but everyone in the Philips Avent bottles noiseless vonstatten.
