I need a deep winter system for a forthcoming trip and I am buying an outer bag to use with my existing sleeping bag
However I have two very similar sleeping bags, both are the same design and expedition cut; bags are my 2 J&H Ultras; one has 900FP down and the other has 650FP down
There is a 200 gram difference between the bags; one is 1050 grams using the 900FP the other using the 650FP is 1210
Both bags are the same age and about the same usage and have suffered about the same 10% loss of loft. I am taking one in to have it cleaned and topped up with an additional 100Grams of down this W/E
Intuition is telling me to get the bag with the lower FP down topped up with some new stuff and use that as the inner but I am having second thoughts
Is my intuition wrong?
