What to know before buying

Listing details to confirm

The listing gives conflicting season descriptions, calling the bag both 3-4 seasons and 3 seasons. Its stated temperature range is -8°C-11°C/17.6-51.8°F, but the separate temperature-rating field says only “Comfort”. Weight is also inconsistent: details list 0.69 Kilograms while the feature text claims 565 grams. Confirm the selected variant’s actual specifications and temperature rating before relying on it for cold-weather trips. The title calls it waterproof, but no waterproof rating or supporting specification is provided.

The supplied evidence contains aggregate ratings but no customer-comment summary, so specific strengths, complaints and reasons for ratings cannot be attributed to customers. The overall rating distribution is mixed. For a buyer, this offers limited guidance on comfort or warmth, particularly because the listing itself gives conflicting season and weight details.

Frequently asked questions

What temperature is this sleeping bag rated for?

The listing states a temperature range of -8°C-11°C/17.6-51.8°F, but the separate temperature-rating field says “Comfort” without a numeric value. The season descriptions also conflict, so verify the rating for the selected version before cold-weather use.

How much does the sleeping bag weigh?

The details list 0.69 Kilograms, while a feature claim says 565 grams. The listing does not resolve the discrepancy, so confirm the weight for the selected version.

Can it be opened out or joined to another bag?

The listing describes a two-way zip that can open the bag as a quilt or connect two sleeping bags. Compatibility with a second bag is not specified.

Is a storage bag included?

Yes. Storage Bag is named in the included-components field.
