What to know before buying

Listing details to confirm

Temperature details conflict: the specifications give 10°C comfort and 5°C extreme, while feature copy claims use between 10°C and 0°C and an extreme rating down to -5°C. The title also says 3-4 seasons, whereas specifications say 3 Seasons. Waterproof wording varies with water-resistant claims, and the stated weight range of 1.6kg–2.7kg conflicts with the listed 1.6 Kilograms. Check the selected listing and intended conditions before relying on these claims. The listed ratings describe a sleeping bag, not a guarantee of personal comfort.
