I have the cloud cover, it's light, packs down well but it's not particularly warm with only 200g of filling. My other half bought the below bag from Decathlon and I'm pretty jealous. Packs down to the size of a 1l bottle and is a lot warmer than my cloud cover. With a down jacket on, I personally find it comfortable to around 2c. You also have pretty good warranty with Decathlon who seem to replace like for like with no questions asked.
