We love the the Thermarest Questar HD sleeping bag. It might not be the lightest bag that we sell or have the highest fill power down compared to some bags but it has loads of great features that you will definitely appreciate. Clearly lots of thought has gone into the design of this bag by Thermarest and it shows.

Thermarest says:

Three Season Comfort in a Feature Packed Hydrophobic Down Bag This is the feature-packed down bag you’ve always wanted.

We’ve loaded this bag with the comfort-enhancing hallmarks Therm-a-Rest bags are known for, such as our SynergyLink Connectors, which integrate the bag with a mattress, and our ThermaCapture Seams that trap your radiant body heat. Stuffed with water-resistant 650 Fill Nikwax Hydrophobic Down, and sporting integrated Quilt and Blanket Loops for sleep system customization, the three-season Questar is ready for your next backcountry adventure.

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

Nikwax Hydrophobic Down

Used in all Therm-a-Rest 3 and 4-season sleeping bags. Nikwax Hydrophobic Down absorbs 40% less moisture than untreated down. This keeps you warmer over a greater range of conditions, and allows it to dry and restore performance faster. And since all water-resistant down treatments wash out over time, Nikwax Hydrophobic Down is specially formulated to be easily retreated at home using Nikwax DownWash and DownProof, ensuring the long-term water-resistance performance of your bag.

In addition, unlike other treated down, Nikwax® Hydrophobic Down is a water-based formula that’s Flourocarbon-free (a.k.a. PFO’s, PFOA’s or PFC’s) and safe for you and the environment. We found this a particularly compelling reason to go with Nikwax, as questions are increasingly raised about the long-term effects of these chemicals and their persistence in our bodies and the environment.

Toe-asis Foot Warmer

The patent-pending Toe-asis Foot Warmer helps to rapidly warm cold feet, offering a baffled pocket of insulation in the footbox of our Women’s down and synthetic sleeping bags. Just slide your feet in for maximum warmth. Leave them out and you’ll still benefit from an extra layer of insulation in the foot of your sleeping bag.

Zoned Insulation

Zoned Insulation puts loft where you need it most – on top of you where it traps rising heat. Beneath you we use less fill, where your mattress already insulates you, and the value of lofted insulation is already minimized by compression. This is possible because our sleeping bags integrate with your mattress, keeping it properly oriented to maximize warmth and save weight.

SynergyLink Connectors

The key to our System Solution is our patent-pending SynergyLink Connectors. Integrating mattress and bag, they make sure you stay on your mattress while you roll freely for the best nights rest possible. Two elastic bands create a snug fit around any mattress up to 25 inches (63.5 cm) wide, keeping your bag centered and eliminating problems with sliding off your mattress or getting your bag twisted around you.

Sleeping Bags

Applied to the backside of the inner lining material of our sleeping bags, ThermaCapture not only boosts warmth without the added weight or bulk of additional fill material, creating a lighter overall bag, but it also lets you warm-up faster – a real plus on a cold night

We love the the Thermarest Questar HD sleeping bag. It might not be the lightest bag that we sell or have the highest fill power down compared to some bags but it has loads of great features that you will definitely appreciate. Clearly lots of thought has gone into the design of this bag by Thermarest and it shows.

The bag is filled with 540g 650 fill power Nikwax treated hydrophobic down. This results in a bag that plumps up easily with loads of loft from the down. You can be confident this bag will have no problem achieving it's stated comfort limits.

Those who suffer from cold feet will love the internal down filled foot warming pocket. The footbox is already well filled with down but you can slip you feet inside this down filled pocket for even more warmth!

For side sleepers and restless sleepers, the SynergyLink system will be very popular. There are removable elasticated straps that you can fit to the bag which hold the bag to your sleeping mat. No more waking up with the sleeping bag twisted around you, falling off the mat or finding the zip has disappeared underneath you. They have been well positioned so when in use the bag doesn't feel constricted at all.

The bag comes with a compression stuff bag which will reduce the pack size by around 50% from the quoted 23 x 36 cm to more like 23 x 20cm.
