“Best cup I've purchased! I love that is does not leak and it is so handy to carry around with me. I'm thrilled about all of my hydrojug purchases, but I think this one is my favorite!”
One thing that may cause that is closing the straw too fast after drinking so the water gets stuck in the straw and come out. Try closing your straw slower and letting the water travel back down in the bottle. Let us know if the issue still persists and send us a video of the leak at service@thehydrojug.com In the video show your straw being up for 2-4 seconds then close the straw and flip the bottle.
“I ordered a cup for both my husband and I. Black for him and pink sand for me. Black came perfectly! Pink sand has scratches all the way through the paint. Customer service was very timely and sent me a new one right away.”
“I love it! I’ve had other similar bottles but this one wins for many reasons. It does not spill or leak, the straw folds down and up so easy, easy to clean, the soft base is so nice, the clear top is awesome. I just love it.”
