When you're making an epic ascent or trek, you want a sleeping bag that will keep you comfortable when the temperatures really start to drop. 

Marmot has taken their best-selling Trestles Elite Sleeping Bag series and made their most sustainable sleeping bags ever, without sacrificing up-mountain performance or durability. 

The Trestles Elite Eco 0 Sleeping Bag is an environmentally friendly update which features Marmot Upcycle® PFC-free and recycled shell, lining, and fill. HL-ElixR™Eco Micro synthetic insulation uses a unique blend of three fibers for maximum warmth, soft handfeel, and high loft. 

Wave construction on top and a blanket construction on the bottom provide optimal warmth and comfort. An anatomically 3D footbox and a fold-down secondary zipper offer ventilation and easy access for this mummy sleeping bag. 

The Trestles Elite Series has been designed for treks where every ounce counts, so Marmot kept the lightweight and easy compressibility of the original.
