A new frontier in green development is the sleeping bag from recycled materials. This is probably a bit hard to track down as Marmot is not widely sold in Australia.
From the company: “The Marmot Eco Pro sleeping bag is a synthetic bag designed for sustained chilly, wet weather while backpacking, mountaineering and river rafting and is built using recycled fabric and insulation”.
It uses the Marmot UpCycle® technology, which aims, according to the company to “minimize our impact on the environment by using natural, organic, and recycled or discarded materials that would otherwise end up in landfills”.
“In our Eco Pro sleeping bag line, we use both an UpCycle® fabric as well as insulation. The fabric is made from recycled plastic soda bottles…hence the name “UpCycle”. When you recycle a plastic bottle, you get another plastic bottle; when we UpCycle® a plastic bottle, we get fabric, a greater value and a broader use. Our Eco Pro insulation contains 80% post consumer waste, and is a hollow core continuous filament”.
Temp Lower Limit: -3.6C
