Compared To

vs Zak straw cup

Zak cups are also popular but some parents find them harder to clean; Boon Swig is preferred for its silicone parts and simpler cleaning.

vs Munchkin 360 cup

Munchkin 360 is good for no-spill but doesn't teach straw drinking; Boon Swig specifically helps with straw skills.

Straw cup recommendation for 13-month-old
We use the Boon Swig straw cup and love it. It’s been leak-proof for us once we figured out how to put the valve in. My son took a few days to get the hang of it but now he drinks from it easily.

Perfect straw cup search
I’ve tried Boon Swig and Zak. Zak is a pain to clean. Boon is easier, all silicone, and my baby likes it. Doesn’t leak if you close the lid. Good for the diaper bag.

Plastic-free sippy/straw cup favorites
Boon Swig is great because the straw and pouch are 100% silicone, no plastic touches the drink. Dishwasher safe. I hand wash the valve though to make sure it lasts. Worth the money for peace of mind.

Best straw cup for 11-month-old
We have the Boon Swig. Love that it’s silicone and easy to clean. My 11mo took a week to learn the straw but now prefers it. No leaks for us. The mint color is cute.
