For my bucket list trip
And because I made a major mistake when ordering from Nunatak.
Trying to go as light as possible was a mistake.
I am in the final pre-planning stage now
I am thinking about how to keep condensation to a minimum while maximising heat retention
PHD use a large cowl over the head to help with this ... 8arfovblo2
I think it is a good idea; rather than a hood I am thinking of insulating the cowl but using a slightly less generous sizing.
I just bought some UL fabric from Simon as it is a much lower GSM than my EPIC but it is windproof and i don't think it would breathe well enough for this type of cowl covering.
Would anybody be willing to take WAG as the the best permeability value needed here?
I am emailing Simon to see if he has any data for the fabric I just bought too
