Marmot created the Trestles Elite Eco series to prove sustainable design does not have to mean a drop in performance. Lightweight yet durable, the shell and lining are made with recycled polyester. Filled with HL-ElixR Eco synthetic insulation, the 100% recycled fibres provide maximum warmth, a soft feel, and high loft. Practical and comfortable, two zips – one full, one partial – aid access and allow the front to be folded down flat. With a three-season rating, the Trestles Elite Eco 20 Long sleeping bag is an excellent choice for UK backpacking adventures. Marmot Trestles Elite Eco 20 Long Sleeping Bag - Estate Blue/Classic Blue
