It depends! If you bought the IMS Combo, there's no need to purchase separate ICEPLATEs. Every IMS Combo comes equipped with an ICEPLATE Curve, Source90 Drink Tube, ICEPLATE MOLLE Sleeve, and freezer cap – ensuring you have everything you need right out of the box. If you just purchase the IMS you will need to purchase our ICEPLATEs separately. Even when you purchase the combo, we recommend you buy extra ICEPLATEs so you can have one in the IMS and another ready to go, ensuring you stay hydrated over a longer duration.
