I am looking to upgrade my sleep system to be able to continue my trail running and wild camping adventures into the winter. It is a big investment for me so I really need to get it right first time.
I am currently using a Berghaus intrepid 1000 synthetic bag (Comfort 5deg, limit 0 deg) weight about 900g and Beghaus Peak Pro inflatable mat (insulated but without an R rating. Weight about 500g. For shelter I am using an Outdoor Research Helium Bivvy which I am sticking with as I am very happy with it.
I have found the bag and mat to have an excellent weight/price/warmth ratio. I can just get by to -2 deg by adding down socks and a down jacket. However, as they are the only ones I have ever used I do not know how much improvement I will get but y.
My questions are:
Mat – has anyone here used the Peak Pro and had the chance to compare it with a mat with an official R value. I am hoping to keep it but as I am looking to switch to a quilt it will become a more important part of my system. What I do not want to do is get a more expensive mat and find out that it is no better.
Quilt – I am currently looking at either a Cumulus 350 (comfort 2 limit -4 deg weight 600g) or 450 quilt (comfort -1 limit -7deg weight 710g). I am leaning towards the 350 as I think it would be more versatile (as well as a little lighter) I would use this for 3 seasons, supplementing with clothing as necessary and then buy an ultralight down bag for summer use.
I would really appreciate any comments, alternative suggestions or advice to help me make a decision. Thanks!
