ICEFLASK® 16.9oz (500ml) Cooling, Heating & Hydration Canteen

ICEFLASK® is a 16.9 fl oz (500 ml) wearable canteen that combines hydration with conductive thermoregulation. Frozen, it delivers up to 23 watts of cooling; filled with hot water, it provides up to 17 watts of heating. The PRC-152 radio-shaped profile fits NATO -152 pouches and mounts to plate carriers using the ICEFLASK® Wing Holster or the ICEFLASK® MOLLE Holster.

• Wearable thermoregulation: Ergonomic, body-conforming shape designed to sit comfortably in radio pouches or holsters and deliver targeted cooling or heating while worn.
• Proven performance: Provides up to 23W conductive cooling when frozen and up to 17W heating with hot water; duration depends on ambient conditions and workload.
• Stackable & multipurpose: Stackable geometry makes ICEFLASK® ideal as reusable cooler blocks or compact heat sources for insulated bags and coolers.
• Robust, field-ready materials: Made in the USA from FDA-approved, BPA-free HDPE for long service life and dishwasher-safe cleaning.
• Precision fit & compatibility: Dimensions match PRC-152 MBITR form factor (3" x 10" x 2") and use a universal 28-410 thread pattern for common Coca-Cola/Dasani caps and accessories.
• Complete options: Available as single units or 7-pack and 18-pack sets; holsters are sold only with ICEFLASK® bottles.

ICEFLASK® is intended for tactical military, law enforcement and recreational use—camping, hiking, overlanding—providing reliable hydration and short-duration thermoregulation. Clean with hot, soapy water or a dishwasher before first use; ICEFLASK® is not rated for independent CBRN use and holsters must be used as instructed for correct retention.

ICEFLASK® Holsters are only sold with ICEFLASK®. ICEFLASK® Holsters are not sold individually/a la carte. Per our Return Policy, all ICEFLASK® canteen sales are final for health, safety, and insurance reasons. ICEFLASK® is only available in Ranger Green. No other colorways are planned.
