Honu Active Cooling Pack

It's warm outside and getting hotter. Feel up to 20°F cooler with the Honu cooling backpack. Whether you're hiking in Hawaii or running in Florida, Honu has you covered. Originally developed in partnership with the US Army in desert environments and US Navy shipyard welders working in dangerously hot conditions, the Honu is ready to tackle all of your toughest and hottest work conditions.

How it works

The cooling pack is designed to actively remove heat from the wearer's body by circulating cool water through patented, thermally-conductive polymer tubing integrated throughout the pack. It leverages the body’s natural cooling biomechanics to reduce the experience of atmospheric temperatures by up to 20°F.

Industry-Leading Performance

Oceanit's advanced cooling garment delivers 3x the body heat extraction of market-leading cooling garments through through nano-material polymers with superior thermal conductivity, improved coolant circulation efficiency, and optimization of coolant temperatures/control to mitigate biological vasoconstriction.


The Honu uses ice or ice packs to deliver intense cooling power to users for up to four hours. Simply fill the included 3L bladder with up to 3L of ice or ice packs and turn on the included micropump to begin circulating water. To extend the length of cooling, simply empty the bladder and replace with new cooling media.
