Questar 0F/-18C Long sleeping bag

The Thermarest Questar 0F/-18C long extreme-cold sleeping bag offers the warmth of an extreme-cold down sleeping bag with the weight and compactness of a summer sleeping bag.

 

Exceptional comfort and light weight 

The Thermarest Questar 0F/-18C extreme-cold sleeping bag uses goose down with an impressive fill power of 650 Cuin.

This down has undergone a hydrophobic treatment developed in partnership with Nikwax, absorbing 90% less moisture than conventional down, retaining its loft much longer and drying 3 times faster. It is ideal for winter conditions. The down meets RDS animal welfare standards, and its treatment is free from PFCs (perfluorinated compounds).

The Questar 0F/-18C sleeping bag has removable SynergyLink connectors for attaching the sleeping bag to your mat. This keeps you securely tucked in without heat loss.

Insulation enhanced by construction and materials:

• In addition to the down, the seams are reinforced with an insulating material called ThermaCapture, which traps body heat inside the bag
• Ergonomic foot compartment to warm feet faster
• Zoned insulation: fill is distributed to reinforce areas that need the most warmth. 70% of the fill is on top and 30% underneath
• Shoulder draught collar to reduce body heat loss and prevent air escaping
• Hood drawcord
• Full-length protective zip flap

Finally, finishing details are also high quality:

• Anti-snag zip
• External zipped pocket

Supplied with a storage sack and compression sack.

We also offer the regular version of this sleeping bag: the Questar 0F/-18C regular sleeping bag
