Set includes (6) leak-proof containers [ (2) 1 cup containers and (4) 2 cup containers], a Patented Jaxx Shaker Cup, a Pocket Vitamin Pack and a large ice pack all inside an insulated bag, the insulated "FitPak" fits right into the side of the Duffel bag that can house your gym clothes, extra snacks, and sneakers! The insulated meal prep bag has a grey PEVA lining that is easy to clean and PVC free, both bags have a full zipper closure. The included leak proof portion control containers can hold a whole days worth of food, pack protein rich chicken and nuts in some and servings of fruits and veggies in the others and they will all stay chilled all day with the included non-toxic ice pack! And don't forget your daily shake or protein drink! The 28 oz. Jaxx Shaker Cup breaks up protein powders and mixes with the powerful patented Jaxx agitator, the agitator is heavier than most due to the metal weight in the middle of the "Jaxx", so it works harder at mixing up your favorite drinks and shakes!
