Cooling BackPack

The world's first cooling pack designed for outdoor adventures in a changing climate.

NASA-inspired technology in a backpack

HONU is a personal cooling system that lowers your body temperature when outdoor temperatures hit 90-degrees or above. Maintain performance, extend your duration, and increase comfort.

A new breed of outdoor climate gear

We’ve spent the past decade developing ThermoCore® Active Cooling technology in collaboration with the United States Military for enhanced cooling gear in extreme environments

ThermoCore® Active Cooling Technology

Liquid cooling is used by NASA Astronauts and Formula 1 Race Car Drivers – ThermoCore® was adapted for personal outdoor use.

4-Hour Duration

The HONU pack uses ice or gel packs to store cold in the pack’s water reservoir for up to 4 hours. Easy recharge in 10 seconds or less!

Extreme Environments

Tested and refined by professional triathletes and avid outdoor athletes in Hawaii’s hottest and most demanding environments.

Cool gear
for hot environments

19°N is on the leading edge of a new wave in climate enhancement equipment

The World is getting Hot

2021 is already setting heat records and 100-degree heat days are becoming more frequent every year. From the “Heat Dome” over the pacific northwest to temperature records being shattered across the US, the earth’s climate is entering a new phase where small increases in global temperatures greatly increase the likelihood of big jumps in extreme heat. Get ready.

Is this the best we can do?

When we looked at current solutions to stay cool outside we found zero good options. What the heck it’s 2021…It’s going to take more than a sun hat, a bottle of water, and a wicking t-shirt to survive outside.

A new breed of outdoor gear

ThermoCore® was designed to maximize the extraction of metabolic body heat and work in conjunction with the human physiology of thermoregulation. 

The improved heat transfer capabilities of ThermoCore® enable a paradigm shift in active cooling technology as previous technologies were limited by rigid and bulky tubes that required significantly more cooling power which made a portable cooling pack impossible to create.

Honu delivers 3-4 hours of cooling

ThermoCore® Active Cooling Technology

Patent pending technology that supercharges cooling your body 

H2O Powered

The Honu pack circulates ice cold water through over 60′ of ThermoCore® tubing across the body

Quick Recharge

Easily recharge your cooling reservoir in 10 seconds or less

SureFit Design

Minimize bounce and increase breathability and comfort

Lightweight

Made of high quality, lightweight, and durable materials

Rechargeable Power System

Uses a small rechargeable lithium-ion battery that can also be used to charge other electronic devices

About ThermoCore® Active Cooling Technology

The patent pending ThermoCore®  technology uses a novel, thermally-conductive polymer material with incredibly high heat transfer properties. The tubing has been biomapped to the human body – optimizing spacing and placement of tubes to maximize heat extraction.

Over 10 Years in Development

The ThermoCore® Active Cooling Technology powering the Honu pack has been more than a decade in the making. Extensive research, development, and military spec testing was conducted to develop a highly durable thermally conductive tubing that is able to operate in extreme environments.

FAQs

The Honu pack uses ice and gel packs to create ice cold water that is circulated throughout the pack to keep you cool when it’s hot outside. Easily recharge your cooling reservoir in 10 seconds or less with a fresh ice or gel pack.

The Honu’s cooling lasts approximately 3-4 hours when filled with 3 liters of ice or phase change ice packs. You can easily adjust the cooling duration as needed for whatever adventure you’re planning!

To recharge cooling, simply add more ice or swap out your ice pack for a fresh one. This can be done in 10 seconds or less with one hand.

On the leading edge of a new wave in climate enhancement equipment, the Honu Cooling Pack is the world’s first active cooling active cooling pack designed specifically for outdoor adventures – from mountain biking, hiking, to just staying active outside. 

The patent pending ThermoCore® technology uses a novel, thermally-conductive polymer material with high heat transfer properties that uses optimized spacing and placement of cooling tubes to maximize heat extraction from the wearer’s body. ThermoCore® is lightweight, flexible, durable, and most importantly offers up to 50% better thermal conductivity compared with PVC or Tygon. The improved heat transfer capabilities of ThermoCore® enable a paradigm shift in active cooling technology as previous technologies were limited by rigid and bulky tubes that required significantly more cooling power and made a portable cooling pack impossible to create.

The idea for the Honu Cooling Pack was conceived in Honolulu, Hawaii, an idyllic setting with a worldwide reputation for remarkable year-round outdoor recreation opportunities as well as a historic proximity to key US military operations. The ThermoCore® Active Cooling Technology was originally developed for the U.S. Army and U.S. Navy to lower core thermal temperatures in extreme environments.

The ThermoCore® Active Cooling Technology powering the Honu pack has been more than 6 years in the making. Extensive research, development, and military spec testing was conducted to develop a highly durable thermally conductive tubing that is able to operate in extreme environments. Made to support up to a half-day of high-exertion activity, the Honu’s active cooling system was tested and refined by feedback from professional triathletes and avid hikers in Hawaii’s hottest and most demanding environments. In controlled laboratory testing, the Honu achieved twice the heat extraction of other wearable cooling products.
