The TETON Sports Deer Hunter -35 Degree Sleeping Bag is designed for very cold conditions, making it a solid choice for camping, hunting, or any outdoor activity in freezing weather.

Zippers on both sides allow easy entry and ventilation control.

Given its weight and size, this sleeping bag is better suited for car camping or hunting trips rather than long backpacking hikes. It is backed by a limited lifetime warranty and responsive customer support, providing added peace of mind.
