Handle Broke in 1 month

1st 3 weeks with this bottle was great. It kept the water cool and the was easy carry. Then I notice one day there was a crack in the handle and before long it fell off. I threw out the paperwork prior to reading the warranty.

Does not hold up after a year of use

The lid leaks, you have to turn it past the point where it secures and even then it leaks.

Great jug, but the silicon seal is moldy

Similar to other reviewers, no amount of scrubbing will get the silicon seal clean. Sadly, I am probably going to throw it away.

Good bottle but cap breaks too easily

My son has had 2 of these water bottles and in both instances the cap has broken from falling off his baseball dugout bench. The metal clip on the first mouthpiece closure broke off and now the bottle constantly leaks. His brand new one fell the 2 ft from the bench onto a dirt floor and the entire clear plastic closure broke off and the thick plastic of the cap cracked. My son wants another but unless I can get just a replacement cap, I’ll go with a different brand. I’ve given Under Armour 2 chances already.


Is there a way to get a replacement piece. Seems like this is an issue with a lot of people.

Under Armour 64oz water bottle

This water bottle has to be the worst I've purchased. Used it one day for football practice and accidentally tipped over and leaked all over my mom's truck, smells like mold now.

Moldy lid - no replacement

Great product. But. The lid has this silicon stopper that has molded and won’t clean and I can’t find a replacement


My daughter begged me for this jug for travel ball but is now regretting it. The bottle leaks bad due to the seal. I went and exchanged it and the new jug has same issue. After talking to some of the other moms on her team they all have had the same issue with the same style jugs. I feel these are not worth the money we paid for them.


This bottle is very big and holds cold and hot drinks very Well.

Cap breaks easily

You’d think after the first one broke easily that I wouldn’t buy a second one but I did. Unfortunately, this thermos only last 3 months before the plastic lid broke. Wish I could just buy replacement lids.
