Our #GETBUCKEDUP logo is a fun add to your shaker bottle collection. We wanted to give you something different and useful. This is a Sport Shaker with 100% Leak Free Guarantee. Plus it is BPA Free and Dishwasher Safe! With our convenient handle its easy to attach to your backpack or just grab and go. It has a built in mixer so you will not have to worry about losing one of those shiny silver balls ever again. The lid has a extremely good seal so we know it will not pop open in your gym bag, lets face it we know nobody has time for that.
