What is the Better Sleep Guarantee?
All Therm-a-Rest sleeping bags and quilts are also covered by our Better Sleep Guarantee. When you wake up on a Therm-a-Rest sleeping bag or quilt, we're confident you'll wake up feeling better than ever. If you are not completely satisfied, return it within three months with the original receipt of purchase and we will give you a full refund- no questions asked.
Why are Therm-a-Rest® sleeping bags so great for side sleepers?
Therm-a-Rest® sleeping bags are designed to accommodate a wide range of sleep positions. Therm-a-Rest sleeping bags are designed with extra room in the torso to allow your shoulders, elbows and hips to move freely. At the head and foot the fit is closer, keeping you warm and decreasing overall weight. In addition, the placement of our SynergyLink connectors is optimized to keep the mattress secure while you roll, yet allow the head and foot of the bag to rotate 90-degrees in either direction, following you for maximum comfort and warmth.
Why should I consider using a Therm-a-Rest quilt?
Using a quilt can save you weight, allow for multiple sleep positions and versatility to your sleep system. To learn more by checking out our blogs on Backpacking With A Quilt and Understanding The Underestimated Camp Quilt.
What is eraLoft synthetic insulation?
Therm-a-Rest® sleeping bags use a unique synthetic insulation that incorporates the best characteristics of both short and long staple insulation. Our EraLoft™ synthetic insulation uses three distinct fibers to create a structure that is lightweight, compressible, warm and durable. The hollow fibers are highly resistant to water and provide warmth even when wet. The insulation is built into Therm-a-Rest® sleeping bags using shingle construction, a configuration that minimizes heat loss and provides the most efficient performance.
How warm is my sleeping bag and what is the EN/ISO Standard?
The new ISO standard has made a few updates to the previous EN rating system. All Therm-a-Rest sleeping bags have been adhering to the most updated standards and tested in our on-site cold chamber. For more info on the EN/ISO testing, head over to our blog.
Is your down ethically sourced?

Therm-a-Rest actively supports industry-wide efforts to ensure all down-filled products are made with the least harm possible. We are opposed to inhumane practices and actively work with peers across all industries to improve the treatment of geese. Our product development team plays an active role in the Outdoor Industry Association (OIA) and its Textile Exchange Materials Traceability Working Group (TEMTWG). Our team also serves on the TEMTWG Down Task Force, working to address key issues in the down and feather industry and manufacturing supply chain.

How should I store my sleeping bag?
Sleeping bags must be stored dry and loose (not compressed) in order to extend the life of the bag. All Therm-a-Rest® sleeping bags come with a compartmental storage sack. For long term storage, the sleeping bag should be stored with the sack fully extended. For short-term storage or when shipping, you can use the smaller draw cord loop in the center of the sack to create a tighter container that saves space.
How do I clean my Therm-a-Rest® sleeping bag?

Follow the care instructions below to help maintain the high quality and extend the life of your down or synthetic Therm-a-Rest® sleeping bag.

 

Hydrophobic Down Care Instructions:

All hydrophobic down treatments wash out over time, and washing is hard on all down. Extend the life of your bag by spot cleaning with a damp sponge, and only machine washing when necessary.

Washing

Hand wash or machine wash in a large capacity, front loading washing machine, using 3 oz. of Nikwax(r) Down Wash(tm). Select cold water and a gentle/delicate cycle with two rinses. We recommend an additional spin cycle as well to extract as much water as possible before drying.

DO NOT dry clean. DO NOT bleach. DO NOT iron.

Drying

Hang dry your bag whenever possible. This can be a long process (24-48 hours or more), but this is by far the best way to get the longest life from your down. Use a well-ventilated, low-humidity environment. Hand-tease or shake out your bag gently to break-up down clumps, and flip it often to help speed the process.

If you need to dry your bag faster, tumble dry in a large dryer on low heat. As your bag gets drier, it will begin to loft and can actually fill the dryer chamber, preventing it from tumbling. This can cause hot spots and even melt the bag's shell, so check it often for overheating and visually inspect frequently to make sure it's tumbling. When you check it, feel for clumps of wet down and either shake the bag gently or hand-tease the clumps apart to redistribute down. Throwing in 3-5 tennis balls can help agitate the bag, breaking up those wet down clusters to speed dry times.

 

Nikwax® Hydrophobic Down Treatment and Re-Treatment

Use Nikwax® Down Proof to restore your down's hydrophobic properties. Specially formulated to renew the Nikwax Hydrophobic Down treatment, it can also be used to provide improved water-resistance to any down bag. Follow directions on the bottle.

Storage

The less time your sleeping bag is compressed, the longer it will serve you by maintaining the loft necessary to keep you warm. Store your sleeping bag loose, in a cool, dry place. If you must store it in a bag, use the extended storage sack it came in, or something even larger. Never use a waterproof bag for long-term storage.

 

Eraloft Insulation Care Instructions:

Washing

Hand wash or machine wash in large-capacity, front loading washing machine. Use a mild, non-detergent soap. Select cold water and a gentle cycle with two rinses.

DO NOT dry clean. DO NOT bleach. DO NOT iron.

Drying

Hang dry your bag whenever possible. This can be a long process (24-48 hours), but this is by far the best way to get the longest life from your bag. Use a well-ventilated, low-humidity environment. Unzip fully and flip it often to help speed the process.
