Helium Bag Terrific
The Helium Sleeping Bag is a great lightweight sleeping bag. It was warm at 20F. It packs really small; down to bread loaf size. Its short zipper is plenty long enough and helps cut down on weight. It offers enough room inside and the hood and draft collar are comfortable. The loft is great. The 900-weight down is worth the price. Its insulation qualities are flawless. It is a wee bit difficult to stuff in the sack Marmot includes. I will upgrade to a better quality compression sack, but this is a very minor criticism. Marmot needs to include a better quality stuff sack for their great bags.
