What Our Gearhead(R) Experts Are Saying: "I use this for protein shakes after workouts-the whisk actually works, it doesn't leak in my bag, and everything stays cold until I'm done."When training days stack up and recovery matters, the24oz Insulated Shaker Bottle keeps things simple. We use it for protein shakes, smoothies, and supplements-any mix that needs to stay cold and go down smooth.
