Marmot created the Trestles Elite Eco series to prove sustainable design doesn’t 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. The Women's Trestles Elite Eco 20 sleeping bag has a female-specific cut, with extra insulation for optimal comfort. Three-season rated; it makes an excellent choice for UK backpacking adventures.
