I read on the Lazy Genius FB page where people were recommending Owala bottles. I ordered the 32oz for my bday from Amazon, but the thing was WAY too big for my hand. Went to Sam's and they have the 2 pack of non-insulated bottles for $9.91. Got a couple sets for us, and we are all in love! The straw feature is easy as is the gulping area. We drank so much water yesterday because these bottles are so awesome. I also orered the smaller insulated one with free shipping b/c we are plus members. Hope someone else enjoys them! https://www.samsclub.com/p/owala-fre...=plp_product_4
