Black+Blum wanted to create a minimal bottle design that celebrated the features of drinking water from glass. They were able to achieve a spout design that was a pleasure to drink from. The stainless steel top and paracord loop give the design a utilitarian feel and the silicone sleeve provides reassuring grip and protection to offset the fragility of the glass. The end result is a pure, no nonsense design that will age well and can become your everyday bottle that you will enjoy using for a lifetime. The thread is on the inside of the bottle so the outer lip is smooth and gives a better drinking experience. It is strong, hard wearing, taste neutral, and it means that no plastic comes into contact with the water.- BPA-free- 100 % leak proof- Thread on inside of the bottle neck for smooth drinking- High quality Stainless steel lid- Paracord carry loop- Handwash recommended- Freezer safe
