FAQ's

What is ICEFLASK® and why does it look like a radio?

ICEFLASK® is a multi-purpose wearable canteen designed to deliver hydration, cooling, and heating in a compact, mission-ready package. Its form factor matches the dimensions of a PRC-152 MBITR radio (3" x 10" x 2"), allowing it to fit into any NATO-152 pouch or wing holster. This design solves the "round peg, square hole" problem of traditional cylindrical bottles, allowing users to leverage unused space on their plate carrier for thermoregulation.

How do I use ICEFLASK®?

ICEFLASK® can be filled with water and frozen for conductive cooling or filled with hot water for conductive heating. Its radio-shaped profile allows it to be worn on the body or used as a stackable hydration source in coolers.

How do I clean my ICEFLASK®?

Cleaning is simple: use hot water and dish soap, or place it in a dishwasher. It is made from BPA-free, FDA-approved HDPE and is fully dishwasher safe. Always wash and sanitize thoroughly before first use.

Is ICECAP Gen 3 compatible with ICEFLASK®?
Cap Compatibility Guide showing ICECAP Gen 3, Valve Cap, and Closed Cap fitment for ICEPLATE® Gen 3, ICEPLATE® Curve, and ICEFLASK™

ICEFLASK® uses a universal 28-410 thread pattern shared with ICEPLATE® Gen 3 and common Coca-Cola/Dasani caps and accessories. While ICECAP Gen 3 fits on ICEFLASK®, use of ICECAP Gen 3 is not recommended because ICEFLASK® does not have a one-way valve.

For more information on ICEFLASK® and ICEPLATE® cap compatibility, please reference our Cap Compatibility chart.

How long does the cooling and heating last?

Cooling and heating duration are influenced by several factors including solar exposure, ambient temperature, and workload. In extreme conditions, testing has shown a range of 15-45 minutes for coolingand30-60 minutes for heating. To maximize performance, we recommend keeping units in a cooler until they are needed for deployment.

Can I paint or rattlecan my ICEFLASK®?

Yes, spray paint is an effective way to break up the visual signature of the unit for tactical environments. However, be aware that paint may degrade over time due to friction from holsters. We do not recommend painting units that will be used in coolers or in direct contact with food.

Is ICEFLASK® rated for CBRN use?

ICEFLASK® is not currently rated for independent CBRN use. It is designed for tactical military, law enforcement, and outdoor recreational activities.

Why use ICEFLASK® for humans and K9s?

ICEFLASK® serves as an environmental inoculation tool. For K9 handlers, it provides a compact way to help prevent heat exhaustion in working dogs. The ICEFLASK® K9 Holster extends the same proven thermoregulation benefits to canines that humans have utilized since 2016.

The ICEPLATE® Gen 3 is like a car battery and needs a ‘Chassis’ to be used to its full potential (sleeve, backpack, or vest). Whether you need cooling, heating, hydration, or a combination of the three, we have a range of vests and backpack ‘Chassis’ that optimize ICEPLATE® Gen 3's power.
