Great bottle. Without plasticizer because of Tritan (copolyester). Unlike many other bottles is thick and does not go by itself on. The opening is slightly larger than that of mineral water bottles and therefore easier to fill but still pleasant to drink from it. Speaking of mineral water: here in Austria will cost a 0.5l bottle brand mineral of about 50 cents to 20 bottles so you have the investment indoors and there is no waste. This 1L is version perhaps somewhat bulky, but it comes from a long time. Best Buy!
