Therm-a-Rest Boost 650 Down Sleeping Bag 20F/-6C Regular (183 cm) - Morning Blue

The Therm-a-Rest Boost 650 Down Sleeping Bag is a lightweight, packable 3-season bag designed for backpackers and campers who demand warmth without bulk. Featuring 650 fill Nikwax Hydrophobic Down and a box baffled construction, this bag provides excellent insulation even in damp conditions. The Regular size fits users up to 183 cm (72 in) and offers a comfortable shoulder girth of 147 cm (58 in).

Advantages

Nikwax Hydrophobic Down treatment repels moisture and dries faster than untreated down. The SynergyLink™ Connectors integrate with sleeping pads for enhanced stability and warmth. Zoned Insulation places more fill where you need it most, while the draft collar seals in heat. The included stuff sack compresses the bag to a compact 28 x 15 cm (11 x 6 in) for easy packing.

Suitable for

• Backpacking and hiking trips in spring, summer, and fall
• Camping in temperatures down to -6°C (20°F)
• Sleepers who prefer a mummy-style bag with a roomy footbox
