大家给小学生都带啥样的water bottle去上学？

I'm looking for a re-usable water bottle for my elementary-aged kid to bring to school everyday in his lunch bag or school backpack. It has to be spill proof, no strong plastic smell, and the opening needs to be wide enough for cleaning. I havn't found a good one in local supermarkets under Sterilite or ZipLoc brands. I'm wondering if moms here have any good recommendations.

In the past, I have packed in my kid's backpack with store-bought items, such as, juice pouch/box and 8oz bottled water etc. I'd like to see what other options are out there.

Thanks!
