Hi.
I am trying to choose between this two down jackets.
https://www.phdesigns.co.uk/yukon-down-pullover-k-series?osCsid=80unhglgq5lagdm8ho32ov5c73
https://nunatakusa.com/skaha-ultralight/138-skaha-down-sweater-classic-version.html
Both are ultralight, have baffled box construction and just a short zipper (sweater-like)
PHD does not disclose the fill weight, so I can’t compare it.
PHD has 1000FP (EU standard), Nunatak 900FP
Nunatak Skaha has Ultrashell (40 gsm)
PHD Yukon has Pertex Quantum (28 gsm)
Both weight 350 grams but the difference of FP should mean that the Yukon should give more warmth for the same weight.
But the difference in shell should mean that the Skaha should give more warmth for the same weight.
Is Ultrashell better (more durable, more water resistant, more vapor diffusion?) than Pertex Quantum, in a way that this add of weight should mean something positive?
Which one would you go for?
thanks guys
Jose
