VIEW AS:
The Hispar 500 sleeping bag and the Hispar jacket are both high mountain lightweights that make a great team for peaks around 7000m like Aconcagua. The jacket is rated at -30°C (-22°F) for your ascent. Wear it inside the wide-cut bag at night (along with the trousers and socks) and you'll boost the bag rating all the way to -35°C.
