Mainstays Pro 24 oz Purple Stainless Steel Double Wall Water Bottle, Straw Top

Seems like solid construction and quality. Thought out design ensures that the entire mouthpiece stays protected but is still convenient, which was the main feature I was looking for. I like that it holds a lot but is still sleek enough to fit in a bag or cup holder. And the rubber/silicone gaskets are removable for cleaning so it shouldn't mold

Love these Mainstays 24 oz water bottles %26 have them in several colors, including the updated version in both black %26 white. They're practically indestructible (ask me how many times mine have been dropped) and they easily keep drinks cold for hours. I've even had ice last overnight (12 hours or more). I find the lid/straw design of the “updated” black %26 white versions a bit easier to drink from than the originals, but it's a very slight difference and largely just a matter of personal preference. In my opinion, you can't go wrong with any of these bottles and they're a great value for the price!
