Which size bags would fit my womens Helium...
Which size bags would fit my womens Helium and my mens Helium long membrain or are they both going to fit in the same size?
For any compression sack, size it the same as the the stuffed dimensions on the sack that came with your bag(s). I think for the Heliums that's about 6x12". For this STS comp sack, that works out to the Small. That said, my tendency is to accept a slightly larger diameter (but still the same finished length) in trade for not fighting stuffing and rolling the top of the sack every morning, so I always use one of my mediums for my Marmot 0*. Too much compression, too often, really damages down...just so you know.
