This is the third set that we've bought and we love them. Definitely leak proof and keeps drinks cold with no sweating. If i had one complaint, the lids have cracked twice when dropped, but that has not stopped us from buying them again.

My water stays cold extremely long, sometimes the next day or two if there is any left in it. My husband takes his to work and says his water is ice cold even after sitting in a hot truck all day.

Larger than I anticipated, but great quality. Love the leak proof with lock and easy one hand open the lid. Plan on purchasing a couple more as gifts.

Quality materials, nice design, well made and very lightweight. Maximum size for bicycle carrier which is what I wanted. Easy to unscrew cap to fill and clean. Seems simple but I’ve been looking for this exact item for years.

Love love love it. !!!! It fits in cup holders, drinks stay cold, and cup does not sweat , oh and it has a lock on it also.I bought 4 of them. Gave 3 away! I just ordered 8 more!!!! Great gifts. I work in a warehouse.

First one I had my mom bought a 2-pak and we shared. I still have it and have carried it everywhere. It is my go-to water bottle. Love the easy open top. I can open it with just one hand when I am driving. Keeps ice a LONG time.

Great fliptop lids, keeps liquids hot or cold. Downside, mold on lid gasket, can't scrape it off or clean it off with anything. You also can't buy replacement parts, like the bottle gasket or the removable drink spout. You can verify this on their website, mold, since it won't let me upload a pic

These Zulu 26oz bottles are the best!!! I LOVE them. Bought them 4 years ago and worked in a super hot factory. It kept my water ice cold. Still use them Dailey. I always have one with me everywhere I go. Now buying some for someone else that loves my bottles.

These lids have a reputation for breaking and Zulu has non-existant customer service despite their lifetime warranty. They don't respond to their customer service email or the warranty form. Sam's Club came through with their great refund or replacement policy but I'd steer clear of these.

We really like these bottles. We've actually bought three sets of them. HOWEVER, the lids are a problem. Three times they have broken. One just failed and the other two broke when dropped about 2 feet out of the fridge door onto laminate floor. The bottles themselves are really sturdy and stay cold. The lids not so much.
