Kid's Cup with Straw Lid

Silicone only

Recycled-steel cup with a stainless steel straw and silicone lid/flex-tip - no plastic in the drink path, unlike the older PP sippy cap.

Plastic-free verdict: Silicone only

The 10oz Kid's Cup is 90% post-consumer recycled 18/8 stainless steel, and the matching straw is stainless steel too, topped with a soft silicone flex tip. The Straw Lid itself is food-grade silicone. So with the straw lid, the entire drink path is steel + silicone - no plastic. Note the OTHER lid you can buy for this cup, the Classic Sippy Cap, is polypropylene; pick the silicone straw lid (or the silicone Sippy Lid) to keep it silicone-only.
