Design and Versions
The Ferrino Diablo sleeping bag boasts a sarcophagus design, ideal for expeditions. Its mummy shape minimizes heat loss and maximizes warmth.

This model comes in two versions: the 900 and the 10000. The key difference lies in their thermal capacity, weight, and packed size, although these variations aren't drastic.

Both versions share the same exceptional compressibility, a hallmark of goose down sleeping bags. This makes them perfect for backpacking and travel.
Weight, Size, and Packability
The 900 version weighs 860g, while the 10000 version weighs 130g more at 1060g. This roughly 200g difference is notable but manageable.

Packed size varies slightly. The 900 version measures 30cm x 35cm compressed, and the 10000 version is 33cm x 38cm when compressed.

Their compact sizes make them easy to fit into backpacks, even alongside other gear, a significant advantage for adventurers.
Materials and Fill Power
Both sleeping bags utilize high-quality 700 fill power goose down, known for its excellent warmth-to-weight ratio.

The 900 version has 400g of down, and the 10000 boasts 500g. The outer shell is made from 100% recyclable 20D ripstop nylon, offering both lightweight and durability.

The inner lining is made of 100% recyclable 40d polyester. This ensures both bags are sustainable and high-performing.
Temperature Ratings and Features
The 900 version has a comfort rating of -5°C to -22°C, while the 10000 offers a wider range of -9°C to -28°C.

Both bags feature a construction that minimizes heat loss, with strategically placed seams. The One-Touch opening system allows for easy one-handed access.

Additional features include an adjustable hood and (in the 10000 version) a collar for enhanced temperature regulation, plus an internal pocket for small essentials.
Conclusion and Recommendation
The Ferrino Diablo sleeping bags are exceptionally lightweight and compact, making them ideal for various adventures.

The high-quality down fill, durable materials, and thoughtful design features make them a premium choice for those needing warmth and comfort in cold conditions.
While the 10000 model offers superior warmth and a wider temperature rating, the 900 is a lighter option for those who prioritize weight savings. Both are excellent options; choose based on your specific needs and preferred temperature range.
