Bought this a few years ago with the intention of using it to go mountaineering. I was hoping to climb Mount Blanc but, needless to say, that never happened. The bag is’as new’ and has never been slept in. It has been stored loosely in its large storage sack inside another holdall in the loft. Comes with Stuff sack and storage sack as per pictures. I borrowed these specifications from elsewhere on the internet. Remarkably light and compact, the Helium delivers impressive insulation. Use it as a three-plus season bag to substantially reduce your load while backpacking and mountaineering. Updated with our Down Defender treatment offering an extra level of moisture protection for sleeping bags exposed to wet environments.
