Therm-a-Rest Questar

The 20° F rating is the 'limit' temperature, meaning it is designed to keep you from becoming hypothermic at that temperature. For most people, the comfort rating of 32° F is a more realistic guide for a restful night's sleep without feeling cold.

The Questar features a W.A.R.M. fit, which is slightly wider than a traditional mummy bag to accommodate side sleeping and shifting positions without feeling like you are being constricted.

These connectors are elastic straps on the underside of the bag that slide over your sleeping pad. They keep your bag centered on the pad throughout the night, preventing you from rolling off onto the cold ground.

The bag uses Nikwax Hydrophobic Down, which is treated to absorb less water and dry faster than untreated down. While it performs better in damp conditions, it is still down, so you should still take standard precautions to keep your sleep system dry.

The Toe-asis is an insulated, ergonomic foot pocket at the bottom of the bag. It is designed to trap heat specifically around your feet, which are often the first part of the body to get cold.

Yes, it includes an integrated draft collar. This helps seal in your body heat and prevents cold air from entering the bag when you move or shift during the night.
