Review: Great water bottle for kids. Easy to open and holds a good amount - I got this Hydro Flask kids water bottle for school and it’s been great so far. It keeps water cold basically all day, which is a big plus, and the straw lid makes it super easy for kids to drink without spilling everywhere. It feels really sturdy too—definitely holds up to drops and being tossed around in a backpack. The size is just right for school, and it fits in most cup holders. Only small downside is it can be a little pricey, but the quality makes up for it. Overall, a solid, reliable bottle for everyday use.
Review: Invest in this one! Great for 2 and up - This is our favorite water bottle to date for our toddler and we have tried them all! Leakage: Let me preface by saying our little guy is 2.5. This is important because it advertises for 3 and up. The cup will leak if the straw portion of the cap is left open and the bottle is full and tips over, so if your child doesn’t quite understand to close the lid you may end in some frustration but he has been capable of remembering to shut it since 2. We loved our contigos that didn’t leak but the reason we switched was cleanliness. Cleanliness: this is where this water bottle in particular takes the cake. We have tried the plastic Contigo and the stainless steel Contigo, and while we loved each of those for different reasons in different seasons of his growth, it was impossible to keep the lid and mouthpiece completely clean and mold free. Nothing is more frustrating than using the tiniest of brushes and toothbrushes to try and clean a cap and nothing seems to work. This one is so simple and has minimal parts and crevices to clean. The straw is easily removed, the rubber ring is easy to remove, and the plastic mouthpiece is much easier to clean than the rubber ones. Hallelujah! The rubber on the bottom is easily removed to clean underneath. Durability: So far it has survived some falls from the dining table and countertops, sliding around on our wooden deck and we have no scratches or dents! I for sure thought he would have caused some damage by now but I’m very impressed with the strength of this bottle! The rubber bottom seems to make a difference Grip: East for little hands! Our son particularly likes to hold the loop that is on the cap, but the bottle is slim enough for little hands to easily hold it while drinking and the rubber on the bottom adds additional grip so it’s not sliding through hands and falling.
