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!

I got the Spider-man version of these bottles for my two boys ages 10 and 6. They are nicely made and look cool too. You get two 20 oz bottles which are a good size for older children. They have the flip top which has a small switch to lock it so it doesn’t just pop open on its own. They are also stainless steel which helps to keep their drink colder longer.

I've had these for 4 months and the release button stopped working. My husband and I can barely manage to release the spout, which means my daughter is unable to use it at school. Waste of money.

Spectacular cups. Nice size, doesn't leak (when top is closed/secured), really solid construction; they're really quite heavy. Kiddo loves 'em, and they seem like they'll keep the drink cool very well throughout the school day.

Super cute and adorable tumblers. They are perfect for my kids and keeps there water cold all day long. They have a twist cap which keep it air tight. Easy to clean and assemble perfect fit for backpack.

I got these water bottles for my kids. They love it. My kids are very picky about their water bottles. It’s hard to find one that they like. These are very easy to clean. And the material is super durable.

I was surprised at how large the bottles were and we’ve always had great luck with Zak products. I love the locking option on the lids and the silicone grip on the bottom of the bottle. Water stays cold and so far no leaks!

I finally have a water bottle for my kids that’s doesn’t make a mess. I use it when we fly and when we go to the park. It’s comes in very handy since I don’t have to worry about helping my kids drink from it . They can do it all by them selfs.

These are great so far for my elementary kiddo's school water bottle. Good capacity, fantastic insulation! Design work is done well, I think it will stay put for a while through use/washings, unlike most insulated tumblers we've had in the past.

Great Quality and Durable water bottles from Zak. The straw less, snap open spout is easy for my kids to use and drink from. The bottles are sturdy, the right height, and don't tip over easily. I would definitely purchase for all my kids.
