Temperature Ratings

Be careful when choosing a sleeping bag. At present there is no standardized rating system.

• Eureka ratings are based on a combination of test results and taking into account environmental and physical effects.
• Our Comfort Rating is a range where most users would realize a good night’s sleep at the listed temperature. We recommend you make your selection based on the Comfort Rating temperature ratings.(Note women, older people, tend to require a sleeping bag even a few degrees warmer.)
• Our Extreme rating is a temperature where sleep would be uncomfortable but providing a measure of warmth.

Rteq insulating fibers have been selected for Eureka sleeping bags resulting in superior performance now, and years ahead.

• A 4 fibre blend combines ‘suspension’ fibres, creating and maintaining loft, with micro hollowfibers, for maximum heat retention. The end result is an insulation that will be both warm and durable.
• The finely tuned looming process enables Rteq insulation to be made in much thinner thicknesses than most other insulations. Rteq insulation is then layered to attain the desired warmth retention for a specific sleeping bag design, with the added benefits of excellent loft and the elimination of insulation shift.
• Multiple layering eliminates any cold spots that can occur in other looming processes.
