Better Than Competing Brands

Unlike many bulky sleeping bags sold in Australia, the Naturehike CW400 delivers premium down warmth in a lightweight package. Other brands in the same price range often use synthetic fill, which is heavier and less warm. Naturehike balances affordability, quality and performance, making it one of the best value down sleeping bags for Aussie adventurers.

Feeling Warm Enough? ❄️🌟

Now, let's answer some of the top questions you might have:

1. What seasons is the CW400 best for in Australia?
The CW400 is designed for all four seasons – spring, summer, autumn and winter. With a comfort rating of 5°C, a limit of 0°C, and an extreme rating of –11°C 🥶, it’ll keep you cosy on coastal camps, bush treks and even cooler alpine trips.

2. Is it suitable for winter camping in the Snowy Mountains?
The CW400 has an extreme rating down to –11°C, so it can handle very cold conditions. That said, for serious alpine winter camping in the Snowies (especially below 0°C), we’d recommend pairing it with a quality sleeping mat and thermal layers to stay comfortable and safe.

3. How small does it pack down?
The CW400 compresses into its included sack, making it easy to fit into a hiking pack.

4. Is the duck down ethically sourced?
Yes – Naturehike uses responsibly sourced white duck down.

5. Can I use it like a blanket?
Absolutely! Unzip fully and it becomes a quilt for indoor or outdoor use.

6. Is it waterproof?
The shell is water-resistant nylon, which repels light moisture and condensation – not fully waterproof.

7. What’s the difference between M and L sizes?
The L size is wider and longer, perfect if you’re taller or prefer more space.

8. How heavy is it?
M = 760g, L = 900g – ultralight for trekking.

9. Does it have a foot zip?
Yes – you can open the foot zip for ventilation on warm nights.

10. Is it machine washable?
It’s recommended to hand wash or use a professional down-cleaning service to maintain insulation quality.
