The Gym Keg64oz Stainless Steel Sports Water Bottle - Double-Wall Insulated Iron Flask - Leak-Proof Metal Sport Jug - 24 Hours Cold, 12 Hours Hot - Huge Thermal Bottle - 3.5x5.5x11-Inches, Black

LIGHT WEIGHT -This water bottle is exactly what I was searching for. It is super light weight. When empty you can barely tell the difference between it and an empty throwaway plastic water bottle.LOW PRICE -The price on it is fantastic for what it is. Now you have to be aware that since it is low cost the stainless steel was not cleaned well after manufacturing. You will need to soak it in a vinegar and soap solution (water, dish soap, and white vinegar) for about 10 - 30 minutes to help remove the oils and get rid of the metallic taste. Doing that and running it through the dishwasher will get rid of most of it. If it still has a metallic taste, just do that process another time. The metallic taste is not permanent. It just comes from some leftover iron particles present when they produce the stainless steel. Letting it dry out completely and stay dry for a day or two also helps rebuild the chromium oxide layer that protects the stainless steel.CONVENIENT STRAP / HANDLEThe strap is water resistant and a very nice way to carry the bottle. Make sure however that when you run it through the dishwasher that the strap is not hanging down on to the heating element in the dish washer. It will melt the part of the strap that touches the heating element.DURABLEThe water bottle is very durable for a light weight stainless steel water bottle. If you drive over it with a vehicle I am sure it will bend. Any water bottle would. You shouldn't expect anything else. The typical bangs and bumps will not affect it any more than possibly scratch the paint.NICE GRIPPY COATINGThe coating on it has a nice grippy feel similar to the feeling of a Silipint cup (silicone). It does not slip out of your hand as easily as a glossy finish would that most stainless steel bottle have.THE LID IS A STANDARD SIZE (EASILY REPLACED WITH A BETTER ONE)I am not a fan of the lid. The square mouth piece feels odd to me. It does function just fine but I ordered a different lid to replace it with off of Amazon. The opening is a standard size. Lids from my Camelback and Sendestar water bottles fit perfectly on it.

This water bottle is not insulated like it says---ice melts quickly and it sweats like crazy.

I've had this Gym Keg for a bit now and it still holds up. The only thing I notice is that if you put ice in there it might last for about an hour or two then melts but the liquids do remain cold. Definitely recommended for future purchases.

It uses a straw and it's required so you have all the problems associated with straws. It's also very thin metal so any temp transfers immediately to your hand. But it does hold 1.5 litters.

Bought 3 of these for my son because he drinks a ton of water at soccer. 2/3 were fine 1 did leak when sideways but I would buy again.
