Thermarest Questar 0F/-18C Sleeping Bag

The new Thermarest Questar 0F/-18C is a cold-weather down filled sleeping bag with additional width to allow for movement in your sleep and to accommodate natural sleeping positions. It is EN temperature rated as ‘Comfort Limit -18° Celsius’ and is part of a range of Questar sleeping bags with three temperature ratings to choose from.

The Thermarest Questar -18°C is a dependable sleeping bag packed with features that make it a practical, warm and comfortable sleeping bag for UK hill walking & camping in winter or cold weather mountaineering.
The fit of the Questar has been perfected in the Thermarest on-site cold chamber to create the ‘W.A.R.M.’ fit that allows room for multiple sleep positions. Extra width in the shoulder and hip and a generous foot box accommodate movement in your sleep or allow you to curl up or stretch out as you might do at home.
If you prefer your sleeping bag to remain in a fix position so you can move inside it, rather than the bag moving with you, then you can use the  SynergyLink™ Connectors to connect your sleeping bag to your sleeping mat. Watch the video for more details.
The zoned insulation with box wall construction keeps the down fill where you need it most adding to your warmth and comfort, while making the most of the thermal properties of your sleeping mat.

The down filling is water-resistant 650 fill power Nikwax Hydrophobic Down certified by the Responsible Down Standard (RDS).

The Questar is offered in three sizes, and designed to fit both men and women.
