The Therm-a-Rest Parsec is a middle-of-the-road option for sustainability, offering some solid features at the product level. It uses 100% recycled nylon for both its shell and lining fabrics, certified to the Global Recycled Standard. Its down insulation is also treated with a PFAS-free hydrophobic coating and certified to the Responsible Down Standard. Additionally, the bag’s durable water-repellent finish is PFAS free. The only notable drawback is that the Parsec doesn’t incorporate Bluesign-approved materials.


At the brand level, Therm-a-Rest has made progress in sustainability, but there is still room for improvement. On the positive side, its parent company, Cascade Designs, tracks its greenhouse gas emissions through the Change Climate Project and has set reduction goals. The company also offers repair services for all of its products. However, Therm-a-Rest hasn’t published an annual impact report since 2018, leaving limited insight into its recent emissions reduction progress or other initiatives. The company began using reduced packaging in 2018, but no updates have been published since. Additionally, Therm-a-Rest doesn’t offer a resale or recycling program for used gear.


Below, we break down in detail all of the Parsec 20's sustainability attributes at the product and brand level, including links to in-depth articles on relevant topics. For more, see our guide to the best backpacking sleeping bags and our review of the Parsec 20.

With a 20-denier nylon shell, the Parsec lands squarely in the “durable enough” category—stronger than ultralight bags, but still worth handling with care. Its anti-snag zipper guards against self-inflicted tears and the 800-fill down won’t pack out like synthetic fill, making this a solid long-term pick for three-season use.

Choosing durable outdoor gear is perhaps the most effective way to reduce environmental impact—the longer it lasts, the less it needs to be produced. Our proprietary longevity rating evaluates overall build quality based on factors such as materials, fabric denier, component durability (including zippers and toggles), real-world performance as reported by our field testers, and our experiences with the brand. Overall, we feel strongly that reducing overall consumption is a cornerstone of sustainability.

The Therm-a-Rest Parsec’s down insulation is certified to the Responsible Down Standard, as is all of Therm-a-Rest’s down.

The Responsible Down Standard (RDS), set by The Textile Exchange, is the leading certification for sustainably sourced down in the outdoor industry. The RDS ensures that down suppliers use sustainable land management practices, prioritize animal welfare, and provide workers with safe working conditions and fair wages. Third-party audits are conducted at all stages of the supply chain, starting with the farm that supplies the down.

The Parsec features a PFAS-free durable water-repellent (DWR) finish. Cascade Designs, the parent company of Therm-a-Rest, aims to transition all products with DWR finishes to PFAS-free versions by 2030.

The DWR (Durable Water Repellent) finish is a product’s direct defense against outside moisture, and commonly contains PFAS (per- and polyfluoroalkyl substances). These synthetic compounds, known as "forever chemicals,” are found in a range of gear categories, from jackets to footwear. They resist water, oil, and heat exceptionally well, making them ideal for outdoor use, but their nearly indestructible nature also means that they take an extremely long time to degrade in nature, if at all. PFAS can eventually end up in everything from soil to drinking water and have been linked to a range of health issues.

The Therm-a-Rest Parsec features a shell and lining made entirely of recycled nylon. In 2022, Therm-a-Rest updated some of its sleeping bags to be made from 100% recycled ripstop nylon certified by the Global Recycled Standard. However, the sleeping pads that the company is perhaps best known for do not incorporate recycled materials.

Outdoor gear can be made partly or entirely from recycled materials, the most common being nylon, polyester, wool, and down. Some products include a single recycled component or a partially recycled fabric, while others are 100% recycled (generally excluding accessories like zippers, Velcro, toggles, etc.). For our sustainability ratings, we evaluate the amount of recycled materials in a particular product and assign points accordingly.

The Parsec doesn’t contain Bluesign-approved materials. Neither Therm-a-Rest nor its parent company, Cascade Designs, is a Bluesign System Partner. However, Cascade Designs aims for 100% of its softgood products to be compliant with Bluesign chemical standards by 2030.

Bluesign Technologies, based in Switzerland, operates a third-party textile certification system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A Bluesign-approved material indicates that it has undergone a rigorous vetting process based on the criteria above. A Bluesign Product goes the next mile, containing at least 90% Bluesign-approved fabrics and at least 30% Bluesign-approved accessories.

Therm-a-Rest operates company-owned manufacturing facilities in Reno, Nevada, and Cork, Ireland. Most of the company’s products are made in these two factories. Products made in the U.S. or Europe are subject to strict labor and environmental regulations and typically have a lower carbon footprint due to reduced transportation in comparison to global factory networks. Therm-a-Rest thus meets our criteria for responsible manufacturing.

This criterion evaluates a brand's commitment to fair wages, safe working conditions, and reducing its environmental impact throughout the production process. Responsible manufacturing is most commonly demonstrated through certifications and membership in programs such as Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accreditation of Production, and the Fair Labor Association. We also recognize brands that prioritize local production, such as those that manufacture primarily in the United States or Europe, to reduce carbon emissions, maintain better oversight of working conditions, and comply with strict social and environmental regulations.

In 2018, Therm-a-Rest aimed to create minimal product package waste. This included using reusable stuff sacks as packaging for all self-inflating pads. Since then, the company has not updated details about its use of recycled or reduced packaging.

Packaging can add significant waste to an outdoor gear purchase and often ends up in landfills. Many brands are using recycled packaging and/or making efforts to reduce packaging altogether. For example, they may use a certain percentage of recycled cardboard or make efforts to use less plastic or paper across their packaging operation. In some cases, brands also use Forest Stewardship Council-certified paper products, which helps to ensure sustainable sourcing of forest materials.

Therm-a-Rest offers comprehensive repair services for its products. Damage caused by manufacturing defects is covered by warranty, and the company can fix normal wear and tear or punctures for a small fee.

Repair services extend the lifespan of outdoor gear and reduce overall consumption. Some brands offer comprehensive repair programs that can fix a wide range of issues, while others have more limited capabilities. If a brand's warranty policy only covers replacement, rather than repair, these programs usually do not meet this criterion.

Therm-a-Rest does not have a dedicated resale program for its products or offer recycling services. Cascade Designs, Therm-a-Rest’s parent company, has stated a goal of focusing more on product end-of-life recycling, including finding recyclers for scrap nylon, polyester, and foam.

Resale and recycling programs help keep outdoor gear in circulation for longer and out of landfills. The most common form is a trade-in program, where consumers can exchange items for store credit, which is then resold. Some brands accept products back for recycling at the end of their life, thereby reducing waste. Occasionally, some do both.

Therm-a-Rest’s parent company, Cascade Designs, uses the Change Climate Projects Business Emissions Evaluator (BEE) tool to track its greenhouse gas emissions. It set a reduction target aligned with the Science Based Targets Initiative (SBTi). Cascade Designs’ goal is to reduce emissions by 45% by 2030 compared to a 2021 baseline and reach carbon neutrality by 2050.

This criterion evaluates whether this brand measures its greenhouse gas emissions, along with its commitment to reduction and transparency in reporting. Typically, we require brands to follow established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. Most companies use the widely recognized scope categorization system for measuring brand emissions. Those who earn the most points in this category have emissions reduction goals verified by the Science Based Targets Initiative (SBTi), a global organization that helps companies set greenhouse gas reduction targets in line with the goal of limiting global warming to well below 2°C. To verify their goals through SBTi, companies undergo a rigorous assessment process and continual follow-up to ensure consistent progress towards achieving their targets.

Therm-a-Rest has not published an annual impact report since 2018. Cascade Designs also does not publish an annual impact report.

An impact report is an important step toward transparency and accountability on the sustainability front. These reports vary in form but generally cover topics such as material sourcing, greenhouse gas emissions tracking, waste and water usage, supply chain analysis, and packaging efforts. For our sustainability ratings, we evaluate this criterion based on the depth and quality of the information provided in the report, and how often it is produced. Some brands produce their own impact report, while others are published by their parent company. In practice, we’ve found that reports produced by individual brands include more detailed information about their sustainability efforts.
