The Oztent Redgum HotSpot Sleeping Bag is inspired by aerospace-grade sleep research to maximise your outdoor sleep comfort. The Redgum's generous size does not compromise the insulation, and the padding is specifically designed to support core muscle sections for those who sleep on their side and back. A comfortable sleeping temperature is different for everyone, and the Oztent Redgum HotSpot lets you adjust the warmth with five points of active heating. Simply insert the reusable HotSpot Pouches in the pockets of your choosing and have a wonderfully warm night's sleep! Two Redgums can be zipped together for co-sleeping, and one side can have a different temperature profile from the other, keeping you both comfortable.
