For purists who appreciate the understated beauty of transparent glass, we offer the NAAL glass water bottle in its most elemental form - without a sleeve. Crafted from premium borosilicate glass, this option celebrates the bottle’s intrinsic qualities of durability, clarity, and ecofriendliness. It serves as a transparent canvas that highlights the purity of the liquid it holds, inviting you to savor not just the taste but also the visual aspect of your beverage. 

For added personalization, you can select caps in various colors to suit your style, and there are also different sleeves available for the glass water bottle.
