I received this free from Influenster and Gatorade in return for my honest review. I did my research and used it a lot. I wanted to see if it would hold up to every day use, and it does. This bottle is made from stainless steel with dent resistant material. It keeps your drinks cold, especially water, which I switched off with actually using Gatorade too. This is very easy to clean to make sure your water doesn't taste like the last drinks you had. The cap stays on strong even through bumps and the occasional drop when I went biking with it. This is the true sports of all kinds bottle. I even had my kids try it out in between classes, and they noticed they drank more with having this. I will be purchasing a few more of these. The great thing, too, is the spout on the bottle when drinking is surprisingly comfortable on the lips, which allows some good drinks in, and the inside really makes the water flow out smooth. I also love that it's 22oz's but doesn't seem that big, so you end up getting in a good amount during the day with continued use. Go on and shake things up and buy up these bottles cause no worries, their leak proof, and BPA free
