G'day Tony,

It super common for the storage sack to be an afterthought by sleeping bag manufacturers, and this is especially so with entry level or budget friendly gear.
The storage bag has an expansion gusset that needs to be removed after first use.  Even though this can be torn off, we recommend using scissors.  If you are mindful with stuffing it back in the bag, and doing it little by little to get as much air out of it as possible, you shouldn't have any issues.
It is possible the bag will have to be replaced at some stage - even on my OZtent sleeping bags, the storage sack lasted a few months.

G'day Freebird,

These sleeping bags do not feature draw-in hoods. 

G'day Anthony,

The Kingsford -3°C sleeping bag would be the closest match to this one. While the Hybrid is slightly smaller, it features a thicker fill and is fairly similar in the other specs. It's generally recommended to choose a sleeping bag with a rating a few degrees lower than your intended temperature. With this bag, you can expect to stay comfortably warm until around 0°C to be on the safe side. If you want extra insulation, consider adding a sleeping bag liner to the mix. 

G'day Jennifer,

I've just given Coleman a call and they have let me know that Hybrid is the name of the range and isn't a different type of bag to the others. This Hybrid range has been designed in 3 different comfort ratings for colder conditions.
