              My boyfriend drinks coffee all day while working in a variety of places, often outside. A glass insulated thermos is too likely to be broken in his rough and tumble life style. He really likes this one.

              I really like it that this thermos holds 40 ounces of liquid, both hot and cold. I used it for ice water on hot days, and hot coffee on cold days. For coffee, I also bought the optional Hydro Flask Wide-mouth Flip Lid. Everything works great.

                    I work outside and love cold water, but hate buying and using plastic bottles. Bought stainless steel bottle to break that cycle but it wasn't insulated so the water got warm fast. Bought the Hydro Flask and it is great for this, put a couple scoops of ice in it and it will keep water ice cold all day, sitting in the heat of my car! Actually had to figure out the right mix, because I would run out of water and just have ice and it wouldn't melt! Love it, use it every day. Only thing I added is their flip cap, which makes it a lot easier to drink out of.

                      Keeps water cold for long time, even in a hot car. I work outside, don't want to buy plastic bottles, so I turned to stainless steel bottles and filling up at home. Single walled bottles are ok, but don't keep water cold. This works well. I added their flip top lid and now can drink out of it without issue.

                      Keeps my ice water cool all day. The ice stays frozen from morning to night. The bottle is durable and is just the right size. The textured finish looks and feels great.

                        Th cap is hardly insulated at all and the heat leaks out in a few hours through the cap.
                        The heat can easily be felt on the plastic cap.
                        In about 2 hour, very hot water becomes just warm.

                        This is simply the best water bottle ever. It keeps things cold all day, even when the bottle sits in the sun! My only small complaint is that the bottle's size makes it a little awkward fitting in holders designed for 32oz. bottles; but that's being picky. This bottle it overall great!

                        Just a simple insulated water that does what it is supposed to do. Keeps things cold and does not sweat so no water mess inside your bag.

                            A:

                            The Hydro Flask 40 oz Widemouth Insulated Stainless Steel Bottle insulation is comparable to the Stanley thermos. the mouth is more narrow in the Hydro flask so it will let less heat out marginally speaking.
