Spark

I spent months online (checking reviews and watching videos), planning how to stay warm at night during this trip. After much thought, I bought the Sea to Summit Spark SP1 sleeping bag, mainly for it´s weight and compressed volume. Although it´s filled with ultra-dry 850+ loft 90-10 down, I´m pretty sure it won´t be warm enough at Andes ‘high altitudes… but if necessary it can be paired with a liner and/or a vivisac (+ all the clothes I´m carrying).
