Smart design coupled with high performance makes our Hydra range of stainless steel water bottles winners.

The copper coating inside the bottles further helps to retain and maintain the temperature of water 10 hours hot or cold and prevents moisture from forming on the exterior so your bottle does not get slippery.

Review: Very poor quality, water does not stay hot as described….
Review: I recently purchased this amazing water bottle for my kids, and I couldn't be happier with my purchase. After a doctor recommended that my children drink warm water, I went on a hunt for the perfect bottle that would be easy for them to hold. I stumbled upon this gem, and it has exceeded all my expectations. First and foremost, the bottle's design is absolutely fantastic for little hands. It has a perfect grip, allowing my kids to hold it securely without any spills or accidents. The size is just right, with a capacity of 300ml, making it easy for them to carry it around wherever they go. Another great aspect of this bottle is its leak-proof design. I no longer have to worry about spills or leaks in my children's backpacks or lunch bags. The secure lid ensures that the water stays safely inside, providing peace of mind for me as a parent. In conclusion, I highly recommend this water bottle for children. Its user-friendly design, perfect size, durability, temperature retention, and leak-proof features make it an outstanding choice. If you are searching for a reliable and convenient bottle for your little ones, look no further. This bottle has truly been a game-changer for my kids, and I'm confident it will be for yours too.
