The HiZYNICE Zero Degree Extra Large Sleeping Bag is designed for adults who need reliable warmth and space in cold conditions. With a generous 90 by 39 inch size, it provides ample room for campers up to 6 feet 7 inches tall.

The extra room also means you can layer up inside if needed, without compromising comfort.
Warmth is a critical feature here, with temperature ratings clearly outlined. The bag is rated for extreme cold down to 0°F, with a limit of 15°F and a comfort rating around 30°F. This makes it suitable for winter camping or chilly nights in spring and fall.
A insulated draft tube runs alongside the full-length zipper, which is a key detail—it prevents body heat from escaping through that seam, so you stay warmer throughout the night. The shell’s waterproof coating also helps shield you from damp ground or light moisture.
Comfort is addressed with a soft 100% cotton flannel lining. This material feels gentle against your skin and adds to the cozy feel, unlike some synthetic linings that can feel clammy.

This synthetic fill is effective at trapping your body heat, making it a genuine four-season option for camping, hunting trips, or even as an emergency bag in your vehicle.
The insulation is also treated with Coleman’s FiberLock technology, which helps prevent it from shifting or clumping over time, so the warmth stays evenly distributed season after season. Comfort and durability are key in its construction. The bag features a soft, brushed flannel liner that feels cozy against your skin, a nice upgrade from colder-feeling nylon liners.

Down Sleeping Bag Buying Guide
For premium warmth-to-weight, consider a down sleeping bag. It’s the gold standard for backpackers and winter campers who need maximum insulation without the bulk. But not all down are created equal. This guide will help you pick the right one for your adventures.
Fill Power: The Warmth Efficiency Metric
This number (like 600, 800, or 900) measures the loft, or fluffiness, of the down. Higher fill power means more warmth with less weight. An 800-fill bag will pack smaller and be lighter than a 600-fill bag of the same temperature rating. It’s a key indicator of quality and performance.
Temperature Rating: Know Your Limits
Will you be in summer mountains or deep winter snow? Choose a bag rated at least 10°F lower than the coldest temps you expect. Remember, ratings are based on survival, not comfort. If you’re a cold sleeper, go for an even lower (warmer) rating. It’s better to be too warm than miserably cold.
Down Type: Ethical Considerations
Most down is a byproduct of the food industry. For guaranteed ethical sourcing, look for certifications like Responsible Down Standard (RDS) or Global Traceable Down Standard. This ensures the birds weren’t live-plucked or force-fed. It’s a small choice that makes a big difference for animal welfare.
Shell Fabric & Weather Resistance
A high-quality, lightweight shell fabric is crucial. Look for durable, water-resistant treatments. Down loses it’s insulating power when wet, so some bags use a hydrophobic down treatment that resists moisture. This can be a lifesaver in damp conditions, keeping you warmer for longer if things get soggy.
Frequently Asked Questions About Down Sleeping Bag
What is a down sleeping bag?
A down sleeping bag uses fluffy clusters from under a bird’s feathers for insulation. It’s known for being very warm for its weight and compressing small, making it a top choice for backpacking and cold weather camping.
What’s the difference between duck down and goose down?
Goose down generally has higher loft and better insulating power than duck down, but it’s often more expensive. Both are excellent, and high-quality duck down is a fantastic value. The fill power rating matters more than the bird type.
What does ‘fill power’ mean?
Fill power measures the loft or fluffiness of the down. A higher number (like 800) means the down traps more air and insulates better per ounce than a lower number (like 550). High fill power bags are warmer, lighter, and pack smaller, but thay cost more.
Are down sleeping bags good in wet weather?
This is their main weakness. Down loses its insulating ability when wet. Modern bags often have a water-resistant treatment on the down or a durable water-repellent (DWR) outer fabric to help, but you still need to keep it dry. For very damp trips, a synthetic bag might be a safer bet.
How do I choose the right temperature rating?
Think about the coldest temperatures you’ll likely camp in. A bag’s rating is it’s survival limit for most people. For comfort, choose a bag rated 10-15 degrees Fahrenheit colder than the expected low. If you sleep cold, go even warmer.
How should I clean and store my down bag?
Never use a regular detergent! Use a specific down wash or a very mild, non-detergent soap. Always follow the care label. For storage, never keep it compressed in its stuff sack. Hang it in a large closet or use the big storage sack it came with to maintain its loft.
Is a down sleeping bag worth the investment?
If you prioritize warmth-to-weight ratio and pack size, yes. For frequent backpackers or winter campers, the performance is hard to beat. For casual car camping or use in consistently damp environments, a synthetic bag might be more practical and budget-friendly.
In Summary
For teh finest natural insulation, a high-fill goose down sleeping bag is a top choice. It offers an unmatched warmth-to-weight ratio, packing down small for your adventures. This means more room in your pack and less weight on your shoulders. The right bag will keep you cozy on cold nights, letting you rest well and wake up ready for the day.
Remember, the best down sleeping bag for you depends on your specific trips. Consider the temperature ratings and the bag’s fit. A good fit traps heat more efficiently. With proper care, a quality down sleeping bag can be a trusted companion for countless seasons, providing reliable warmth where you need it most.
