What to know before buying

Listing details to confirm

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.
