Adjustable fit
The Boost 650 20F/-6C down sleeping bag from Therm-a-Rest gives you the flexibility to have either a little more space around you, or less space in a mummy shape to lose as little warmth as possible. And all with just a single 2-way zip in the centre! Plus, with the adjustable hood and draught collar, you have even more options for customising this sleeping bag to your needs. With its small pack size and water-repellent treatment, it is particularly suitable for trekking or bikepacking.
In addition, the two armholes, which can be opened and closed using a zip, are another unique feature. They allow you to read a book or play cards while keeping the Boost 650 20F/-6C down sleeping bag closed at the top. Alternatively, they can also serve as ventilation openings.
Good karma is a top priority
The outer and inner material is made from 100% recycled polyester. Moreover, the water-repellent DWR treatment of the outer material is PFAS-free, while the down insulation is RDS-certified and comes exclusively from animals that have been treated well.
