[pct-l] Dress Me Up & Pack Me Out - Sleeping Bag/System
Re:Sleeping Bag/System
So I got the Marmot Hydrogen (not the Helium). Helium generates much heat
from the fusion of 2 hydrogen atoms, so I am assuming this bag is warmer
than the Hydrogen. The hydrogen of course has less atomic weight than
helium. But my question is whether these Silnylon bag covers (which weigh
about 5 oz.) actually add significant warmth to the bags. Not from thernal
insulation, but from cutting heat loss to convective drafts. Anybody tried
these things?
