PHD are leaders in the field for making excellent weight-to-warmth ratio sleeping bags and sleeping systems. How much warmth you need at night is a personal thing although some races do specify a minimum weight/specification.
I tried out the PHD (PH Designs) Hispar 500 Down Sleeping Bag K Series during the Everest Trail Race where the recommended zone was -10 comfort. I wanted to sleep so warmth was a premium requirement for me.

Here is how it performed.
Conclusion
I was toasty warm every night, even on the coldest nights, so this bag obviously did its job. I found I was actually taking off layers during the night as my body warmed up and the bag retained that warmth.
The weight was also good for the amount of heat delivered.
The other thing that I thought was excellent was that the bag was dry in the morning. My tent mate had a different brand and although she was also warm her bag was soaking every day as her body heat caused condensation.
If you are going to be spending time in the cold, then the PHD range offers a lot of options and this bag was absolutely fit for purpose – in this case 7 nights at temperatures of up to -10C.
