Avex Outdoor AVEX MixFit Elite+ 22oz Deep Sea Tritan w/Storage

Um... this this is great. I don't use the vitamin/container add on at all, but the rounded bottom makes mixing and cleaning a breeze. It's very high quality / tough, and the overall lid function is spot on: easy to drink from, no leaks, quick carry, stiff enough to stay open and not fall into your face. Fits in car cup holder. Ball is superior at mixing. Perfect size for post-workout or meal replacement. Tempted to buy another - something I do out of fear of the product no longer being around by the time I have to replace it... which will be a while on this one.
