The Rabbit Ears 25 delivers warmth and packability for warm-weather camping. This guide explains who it fits, who should look elsewhere, and key trade-offs.
Quick answer
The Rabbit Ears 25 is a versatile, lightweight sleeping bag ideal for summer backpacking and warm-weather camping. It offers good warmth for its weight, but its 25°F rating means it's not for deep winter or for very cold sleepers.
Why 25°F matters for summer use
A 25°F temperature rating is a sweet spot for three-season camping. In summer, nights can dip into the 40s or 50s, especially at higher elevations. This bag provides enough insulation to keep you comfortable without overheating. However, it's not a true summer-only bag—it can handle cooler spring and fall nights too, making it more versatile than a 40°F or 50°F bag.
The trade-off is that on very hot, humid nights (above 70°F), you may find it too warm. If you camp exclusively in hot climates, a lighter bag or a quilt might be a better fit.
Down insulation: warmth vs. moisture
The Rabbit Ears 25 uses 600 fill down with a water-resistant coating made without intentionally added PFAS. Down offers excellent warmth-to-weight ratio, which is why this bag is a strong choice for backpackers. The water-resistant treatment helps protect against condensation or light splashes, but down still loses most of its insulating ability when wet.
If you expect rain, high humidity, or damp conditions, consider a synthetic bag instead. Synthetic insulation retains warmth when wet and dries faster, though it's heavier and bulkier for the same warmth.
How to decide if the Rabbit Ears 25 is right for you
- Check your typical low temperature: If your camping nights are consistently above 35°F, this bag will keep you comfortable. For nights below freezing, look for a 0°F or 15°F bag.
- Weigh pack weight vs. moisture risk: At under 2 lbs, this bag is a backpacking favorite. But if you camp in wet climates or expect rain, a synthetic bag is safer. Down is lighter; synthetic is more moisture-tolerant.
- Consider your sleeping style: The Rabbit Ears 25 has a mummy shape for efficiency. If you move a lot in your sleep or prefer more room, look for a rectangular bag or a quilt.
Product spotlight
- Rabbit Ears 25: Based on the top-selling Greystone, the Rabbit Ears 25 uses 600 fill down with baffled construction and a PFAS-free water-resistant coating. The baffled construction prevents down from shifting, so you get consistent warmth without cold spots—important for a bag you'll rely on in variable weather.
