The Robens Serac 300 -4°C down sleeping bag on the left offers the best warmth-to-weight ratio for most general outdoor activities thanks to its standard mummy shape and a choice of down fillings in a box wall construction. Thanks to the high-quality down filling, the sleeping bag is very compressible, allowing for a small pack size, and comes with a compression stuff sack and a mesh sack for optimal storage conditions on tour and at home.
