## Before you buy

- Season and temperature descriptions are contradictory: the details list 3 Seasons and 20°C – Comfort Limit, 10°C – Comfort, 5°C – Extreme, while other copy describes comfort between 10°C and 0°C and use down to -5°C. The title also says 4 Season, and the product is described as both envelope-shaped and mummy-shaped. Treat the temperature performance and cut as unconfirmed, and check the selected listing before relying on either for cold-weather camping. The listing also alternates between water-resistant and waterproof descriptions.

## A good fit for

- Campers wanting a single-person bag for spring, summer or autumn, subject to the unresolved temperature claims.
- Buyers who value a carry bag, accessory pockets and a compressible design.

## Less suited to

- People choosing a sleeping bag specifically for dependable winter use or a verified low-temperature rating.
- Buyers who need confirmed mummy-shaped fit, waterproof performance or a precise comfort rating.

## Customer feedback

Customer feedback reports positive impressions of quality and value, with a mention of use for camping. The overall ratings lean positive, though lower ratings are also present and the available information does not explain why. This feedback may help buyers considering general camping use, but it does not confirm the disputed temperature claims or seasonal suitability.
- Positive themes: Customers describe the bag as good quality.
- Positive themes: Customers consider it good value for money.

## Frequently asked questions

### What temperature range is this sleeping bag rated for?
The details list 10°C as comfort, 20°C as comfort limit and 5°C as extreme, while other listing copy gives a 10°C to 0°C comfort range and claims use down to -5°C. These claims conflict, so do not rely on a single rating without confirmation.

The title mentions both 3 season and 4 season, but the detailed specification lists 3 Seasons. The description supports spring, summer and autumn use, while winter suitability is not established.
### What is it made from and how much does it weigh?
The listing specifies polyester, 250GSM hollow-fibre fill and a weight of 1.3 Kilograms.
