Quantum Bags all have the Quantum Expander, an ingenious way of adjusting the volume of your sleeping bag to respond to changing conditions.

Great bag
i use this sleeping bag sice 3 years, i used it in the Himalaya and for winter trips in the alps.
You can sleep outside without a bivy bag, the Conduit shell material is waterproof. I had no problems at temperatures down to - 28°C.
The quantum expander gives you extra space for comfortable sleeping or for changing the clothes inside the bag.
