Comments about Slumberjack Slumberjack Optimus System Multi-temperature Sleeping Bag and Bivy:
Nine pounds is a lot of weight. I'm not a minimalist, but I do try to keep my gear as light as possible. You can do much better weightwise, and have more room by buying a lightweight tent from brands such as REI, Sierra designs, MSR, Big Agnes, and others...and just about any sleeping bag as well.
The price is right, but I think you will regret the weight.
