It has an outer layer of 304 stainless steel and an inner layer of 316 stainless steel, with a dome-shaped flip-top lid (One Touch Cap) that locks and opens easily with one hand. A Stage 2 straw kit is included.\u003c\/p\u003e\n\u003cp\u003eThe lid and handle are made of BPA-free plastic, and the straw is platinum silicone. Double-wall vacuum insulation keeps drinks hot or cold for up to 6 hours, and the '+' cut straw design helps prevent leaks whether the straw is attached for sitting up or removed for drinking lying down. All parts separate easily for cleaning and reassemble in a few seconds; the cup is not microwave safe, and the maker recommends replacing silicone parts every 2 to 3 months.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOuter layer of 304 stainless steel with an inner layer of 316 stainless steel\u003c\/li\u003e\n\u003cli\u003eBPA-free\u003c\/li\u003e\n\u003cli\u003eDouble-wall vacuum insulation keeps drinks hot or cold up to 6 hours\u003c\/li\u003e\n\u003cli\u003e360-degree handle for a secure grip\u003c\/li\u003e\n\u003cli\u003e'+' cut straw design helps prevent leaks\u003c\/li\u003e\n\u003cli\u003eCan be used with the straw attached for sitting up, or without it for drinking lying down\u003c\/li\u003e\n\u003cli\u003eDome-shaped flip-top lid (One Touch Cap) with a lock feature, easy to open one-handed\u003c\/li\u003e\n\u003cli\u003eLid and handle made of BPA-free plastic\u003c\/li\u003e\n\u003cli\u003eStraw made of platinum silicone\u003c\/li\u003e\n\u003cli\u003eParts separate easily for cleaning and reassemble in seconds\u003c\/li\u003e\n\u003cli\u003eIncludes a Stage 2 straw kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTrustScore\u003c\/h3\u003e\n\u003cp\u003eTrustScore is Birch's proprietary rating, from 0 to 100, built from 50+ signals that reflect what actually matters to parents — safety, materials, recalls, certifications and quality.
