Key Considerations When Choosing a 23ZERO Sleeping Bag

Environmental Conditions
Knowing the conditions you’ll be camping in is essential. Temperature range, humidity, altitude, and seasonal changes all influence how warm or cool you’ll feel at night.

Shelter Type & Heat Retention

Your choice of shelter plays a big role in how effective your sleeping bag will be. Swags and compact shelters retain warmth better by reducing the volume of air that needs heating. Larger tents, on the other hand, allow cold air to circulate more freely.

Body Size & Fit
The way your body fills the sleeping bag affects how well it holds heat. Smaller users may feel colder if there’s too much empty space inside the bag, while larger users naturally trap heat more efficiently. Selecting the right size helps eliminate cold air pockets. In the case of a double sleeping bag, two occupants sharing the same space will generate and retain warmth more effectively due to the combined body heat.

Energy Levels & Physical Condition
Your body’s ability to stay warm depends on more than just the gear. Low energy, hunger, or physical fatigue can reduce your natural heat output. A well-fed, rested camper will stay warmer and more comfortable through the night.

Layering & Clothing Choice
What you wear inside the bag matters. Layering thermal base clothing, warm socks, and a beanie can greatly improve warmth and help your sleeping bag perform across a broader range of conditions. Smart layering can often make the difference between a restless and restful night — especially in cold or changeable environments.
