Marmot Helium MemBrain Sleeping Bag: Old Faithful
In a seven-month period I logged 100-plus days in the Helium in a wide variety of situations: spring snow storms on Mt. Rainier, trekking in India, bivouacs in the North Cascades and more than a few nights in the guide lounge and my VW van. Thinking back on all those trips I can’t recall a single instance where the Helium let me down in any way.
