How warm is this bag for three-season camping?

The Nature Link bag has a comfort range roughly between 42°F and 55°F thanks to its 300g/㎡ imitation silk cotton fill and snug mummy profile that reduces dead air space. It’s suitable for late spring through early fall in temperate conditions, or for cooler nights on the trail when layered with a sleeping pad and base layers.

• Insulation: 300g/㎡ soft imitation silk cotton
• Temperature guidance: approximately 42–55°F comfort range
