In short

The Thermarest Boost 650 32F/0C is a highly versatile sleeping bag designed for both backpacking and car camping, offering exceptional comfort and adaptability. Its semi-rectangular shape provides more internal space than traditional mummy bags, allowing for freedom of movement. The innovative WarmZip center zipper lets users transform the bag into a mummy shape, increasing thermal efficiency and warmth by up to 10°F/6°C. Arm holes allow for easy access, ventilation, and activities without leaving the bag, while two-way zippers offer further temperature control. 

The Boost 650 is lightweight and packable, featuring 650-fill hydrophobic down strategically placed for optimal warmth, and a shell and liner made from 100% recycled nylon. Standard Therm-a-Rest features such as a puffy draft collar, draft tube, cinchable hood, and YKK anti-snag zippers add to its comfort and usability. A PFAS-free DWR coating ensures weather resistance, making the Boost 650 ideal for varied outdoor conditions.
