Requested this item for my grandson going into his first year of full days at school. These were bigger than expected which is good. Love the locking lids to keep from spilling however wish they were spill proof with the lid open as well. Cute designs and love that they are sweat proof. Great quality and overall happy.

These bottles seem pretty solid and time will tell after being used for about a month with my 7 and 8 year olds. They've dropped them many times and a few scuffs only. Zak is a known brand for reason. These vottles are perfect size for the age and plenty of room to keep them hydrated while at school. It says 3+ but they seem a bit big for a 3 y/o in my opinion. These are meant for cold liquids only. They keep drinks cold for half day at room temp in my application. Perfect for back to school.

The 20oz Minecraft Zak duo packs were a great product for kids who are on the go. These containers are a great size for backpacks and holds close to the 20 oz of water. The lock features were a great surprise to assist in accidentally spillage. Currently, there have been no spills. The character images are vibrant with rubber bottoms that act as aound absorbers. Overall, a great start of the school year product!

Wow, wow, wow! These stainless steel water bottle set is the real deal. My son is in love with the Spider-Man one. Super easy to clean up and it even has a carry handle on it making easy for my son to grab. Love that it has a lock feature to prevent it from opening accidentally and spilling water everywhere. Definitely recommend.

These Zak cups are SO cute and sturdy. They’re going to be great for my daughter for school and traveling. The lid is great, it can be easily locked and unlocked so that there’s no spills at all. It definitely keeps drinks cold for a while! The fact that it’s a straw system too is something my daughter loves. I would definitely recommend these. We got the Hello Kitty designs and they’re adorable!

Zak! design stainless steel water bottle pack is great for children of all ages. First, the bottles are much larger than most of the children’s bottles - 20 oz. It’s especially helpful for older kids and for hot days. Second, the bottles keep water cold all day. We went to a rather hot day at a fair (85 + F), and the water was still crisp and cool after several hours in the sun. Third, the handle is very useful for carrying the bottle around as well as a locking mechanism on the lid that makes it spill proof. Overall, these bottles are very well designed to provide all day hydration and have cool designs that kids like.

The Hello Kitty water bottles set stands out with its vivid, eye-catching designs. Each bottle features bright, cheerful colors and adorable Hello Kitty graphics which I love as a collector. The high-quality, bottles ensures durability and resilience, making the bottles ideal for daily use. The vibrant colors are not only attractive but also resistant to fading, even with frequent washing. The sturdy construction means these bottles can withstand drops and rough handling. This set combines aesthetic appeal with practical durability, making it a stylish and reliable choice for Hello Kitty fans.

These water bottles are great! Fun designs that aren’t babyish but are still the character he wanted. And 20oz is a great amount of water for my 1st grader. The stainless steel keeps the water cold all day and there still ice in there. We love these, totally worth it!

My son loves these water bottles. He is a big fan of sonic so we ordered him sonic bottles. They are so well made and easy to carry around. They have kept the water cold for a while even in this hot summer heat. The lock on the top really help keeping his backpack dry so it does not accidentally open in his bag.

My son really enjoyed the Minecraft water bottle! He's obsessed this is the first time he's actually keeping up with the bottle! taking care of it, his Minecraft obsession doesn't hurt and he hasn't lost it yet!! lol I love the spill proof lid since he is kind of a clutz at times prevents me from having wet backpacks at the end of the day it's easy to use lock and unlock my child picked it up quick it's the little touches for me like the silicone rubber at the bottom I have glass on my table so it's perfect preventing accidents my only con is it's not rated for hot liquids but I think that's just because of the design of the lid. The double insulation did keep drinks cold all day though that's always a plus
