[leadin]The last couple years have seen a major renaissance in sleeping bag design. Zippers have been ditched, and closures have changed across the board.[/leadin]
A new entry in the world of re-imagined sleeping bags is the Nozipp. This sleeping bag uses strong rare earth magnets as the closure device, allowing sleepers to open the bag easily and silently to adjust temperature or get out without making a ruckus.
Nozipp claims a remarkable temperature comfort range with these bags because it can be configured in three different “modes.” As a mummy, the brand claims comfort down to 15 degrees. By shifting the down outwards into “roomy” mode, the brand states the bag is good to around 50 degrees. With the bag open, it should be good to around 65 degrees.
