Review on 🌬️ Nalgene Kids On The Fly Water Bottle: Leak Proof, Durable, BPA & BPS Free, Carabiner Friendly - Reusable & Sustainable, 12oz by Jason Gopinath

I have 4 of these in large bottles. I wanted something smaller to take away and I love that they are sealed and leak proof if you close them properly and screw the lids on tight. I say that because the only time they have leaked is when I didn't tighten the caps for some reason. I have been using this type of bottle for many years. Lids are easy to clean. The little soft part covering the hole gets moldy and it would be great to have replacement parts for it rather than buying a whole new lid (because it's just more plastic in landfill and I find it wasteful on the part of the company). . But since I haven't found anything better yet, I'll just buy a new cap. However, I cringe a little when I have to throw the old one, which works great except for the soft part, in the trash because I think how wasteful that is on the company's part.
