Additional Information

• How much warmth does a Reactor Midweight add to a sleeping bag? The added warmth depends on how well the sleeping bag retains heat and how well the sleeping mat insulates. When paired with a quality bag and mat, a Reactor Midweight can add up to 6 °C / 11 °F.
• Which Reactor is the warmest? The Reactor Fleeceweight is the warmest option, followed by the Reactor Midweight, and then the Reactor Lightweight.
• Can a Reactor be machine washed and dried? Reactor liners can be machine washed without special soaps. Do not use fabric softeners. Air dry or machine dry on a cool to warm cycle without dryer sheets.
• Can a Reactor Midweight work as a stand-alone sleeping bag? In summer temperatures and still air conditions, a Reactor Midweight can function on its own for sleepers wearing long base layers. The fabric is not windproof.
