A very elegant bottle covered by a practical insulating pocket with a nylon loop. When I was offered this nice bottle to try it, I loved it right away. I then explored the characteristics of plastic bottles and saw the advantages to keep my drinking water in a glass bottle. This bottle is made of borosilicate glass, which, as I discovered, is commonly known as Pyrex. It is a dense glass, which opposes strong expansion and is, therefore, very safe for hot liquids. It is also very durable and do not break easily. The cap closes tightly, and the last little quarter turn really gives me confidence that nothing will leak.
According to the recommendation, have washed bottle and my wallet before first use. The water really tastes better. Once you get used to taste fresh, clean, it is very difficult to accept the new plastic. The nylon bag (mine is a beautiful dark blue) that fits perfectly, functions as protection, insulation and to allow a good grip. I also like the two washing tools that are included in the purchase. I love!
