I'm currently reviewing the Rab Mythic 200 (we're aiming to publish that in the next couple of weeks)
https://rab.equipment/uk/mythic-200
If you can stretch the budget it's a fantastic bag for warmth/weight/compactness...
Rab say it's "for use in warmer conditions where weight and packsize are crucial to success, such as long multi day routes or summer trekking"
I tend to sleep pretty warm, and for me Rab's figures for the Mythic 200 are pretty much bang on: comfort 6C, absolute lower comfort limit 1C.
