Summit 兒童塑膠水壺（簡易翻蓋吸管）

I was pleasantly surprised how lightweight this bottle is for my preschooler to carry herself. The covered silicone spout hasn't leaked once in her backpack, even when she tosses it in sideways.

My kid drops this thing constantly and the Tritan plastic has zero scratches so far, which is a miracle. The covered silicone spout flips up easily for little hands, and I love that it only leaks when the lid's open—closed, it survives being thrown in a backpack.

The flip straw lid is genuinely leakproof when snapped shut, which saved my bag during a car ride. My only gripe is that it’s a bit bulky for small kid hands, but the lightweight Tritan plastic makes it easy for her to carry around all day.
