On its own, no. IMS is for external, hard cell plate carrier hydration only. However, using our IMS Pro in conjunction with our ICEPLATE EXO Carrier will allow you to receive cooling and heating benefits in addition to hydration.  That being said, if you happen to have a plate carrier with MOLLE attachment capabilities on the INTERIOR then you can use the IMS Pro alone for cooling and heating. If the MOLLE attachment is on the exterior, then it will simply function as the world’s thinnest, flattest, and strongest hard cell hydration solution for plate carriers.
