The REI Co-op Magma sleeping bag excels at sustainability, earning the Better Trail Certified distinction. Its shell and lining fabrics are Bluesign-approved recycled ripstop nylon, and its down insulation is certified to the Responsible Down Standard (RDS) and is also a Bluesign-approved material. The entire sleeping bag is treated with a PFAS-free durable water-repellent (DWR) coating. The only notable omission is that the Magma is not made in a Fair Trade Certified (FTC) factory, unlike many other REI products.

At the brand level, REI is making significant progress in reducing its carbon footprint while offsetting emissions through carbon credits. The company is officially certified as Carbon Neutral and publishes progress updates on emissions reduction and sustainability initiatives in its annual impact report. While REI does not offer repair services, it runs Re/Supply, a resale program that extends the life of used gear, making it easier to buy and sell pre-owned outdoor equipment. Lastly, REI has largely phased out plastic bags in its packaging and uses paper products made from Forest Stewardship Council-certified or post-consumer waste. Overall, the Magma is a top recommendation for anyone seeking a sustainable sleeping bag.


Below we break down in detail all of the Magma 30'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 Magma 30.

The Magma 30’s 15-denier nylon is on the fragile side of average for a sleeping bag. Down fill retains its loft better than synthetic, and the zipper’s anti-snag zipper is a bright spot—but overall, this is a bag that rewards careful handling, not hard 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. Because we feel that reducing overall consumption is a cornerstone of sustainability, longevity gets the heaviest weighting of any attribute in our sustainability ratings.

The down insulation in the REI Co-op Magma is certified to the RDS. REI uses RDS-certified down for all virgin down and feathers in its down products.

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.

This bag has a PFAS-free DWR coating. REI announced that all cookware and textile products it sells would be PFAS free by the fall of 2024. In 2024, it finished its phase-out of PFAS for apparel, footwear, packs, and bags, but has yet to provide an update on cookware products or tents. The company has given brands that produce high-altitude gear—think mountaineering boots—until 2026 to phase out PFAS.

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 REI Co-op Magma contains recycled nylon in its shell and lining fabrics. In 2024, REI used 52% recycled polyester and 45% recycled nylon (up from 49% and 41%, respectively, in 2023) across all REI Co-op products. In 2021, the company signed on to the Textile Exchange’s 2025 Recycled Polyester Challenge, which incentivizes the textile industry to use 45% recycled polyester by 2025. REI has since met and surpassed this goal. Integrating more recycled fabrics has become a significant component of the brand’s greenhouse gas reduction strategy.

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 Magma’s shell and lining fabrics are Bluesign-approved nylon. REI is a Bluesign System Partner, and, in 2024, 71% of the fabrics used in REI Co-op brand products were Bluesign approved (up from 70% in 2023).

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.

REI is a Fair Trade Certified brand partner working with Fair Trade USA. The Magma is not manufactured in a Fair Trade Certified (FTC) factory, but FTC partner brands receive a point in this category for all their products, as participation in the Fair Trade system positively influences a brand’s entire supply chain—even if not every product is made in Fair Trade Certified factories. Many REI products are manufactured in Fair Trade Certified factories, which ensure factories adhere to rigorous social and environmental standards, including fair wages, safe working conditions, and sustainable resource management. In 2024, REI paid a Fair Trade Premium of $718,000, totaling $2.3 million in contributions since 2016. The money goes into a fund owned by workers, who collectively choose how to use it to improve their communities.

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.

REI prioritizes paper-based packaging that is either Forest Stewardship Council (FSC)-certified or made from post-consumer waste. As of 2024, 99% of paper used in REI Co-op product packaging is FSC-certified. The company has largely phased out plastic bags and minimizes packaging whenever possible. Some REI retail locations have eliminated in-store bags entirely. Lastly, REI uses the How2Recycle Label on its packaging to clearly communicate the best way to recycle its 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.

Unlike many competitors in the outdoor industry, REI does not offer repair services for its apparel, footwear, or other soft goods. However, the brand has extensive care and repair articles on its website. It does offer in-store ski, snowboard, and bike repairs and maintenance services for a 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.

REI's Re/Supply program offers an online marketplace for used gear, along with two dedicated brick-and-mortar resale stores in Oregon and California. By trading in gear you no longer need, you help keep it out of landfills and earn REI credit in return. The brand claims that buying used gear typically avoids 50% or more of the carbon emissions associated with new production.

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.

REI is certified under the Change Climate Project’s Climate Label (formerly Climate Neutral), a recognition awarded to companies that fund carbon reduction projects equivalent to their annual emissions. To maintain the label, companies must also set and actively pursue ambitious emissions reduction goals. REI tracks its greenhouse gas emissions using the Higg Index. The company has made emissions reduction targets verified by the Science-Based Targets Initiative. By 2030, it aims to reduce Scope 1 and 3 emissions by 47% compared to 2019. For the past 11 years, REI has achieved zero emissions in Scope 2 by purchasing 100% renewable energy. The company also publishes its annual emissions data, along with reduction progress. In 2024, REI reduced its total greenhouse gas footprint by 12% compared to its 2019 baseline and 7% compared to 2023 emissions.

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.

REI publishes an extensive annual impact report, and it is one of the most comprehensive that we have seen. The report is broken up into multiple sections and is easy to navigate. It includes sections on waste management, greenhouse gas emissions, material sourcing, labor practices, and REI’s initiatives to influence its partner brands to seek more sustainable practices.

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.
