Sea to Summit Comfort Light Insulated Sustainability Report

Durability is solid with the Comfort Light’s 30-denier top and 40-denier bottom fabric, backed by its innovative dual-layer baffle system. However, its hybrid construction creates more internal complexity and potential for weld failure. It holds up well with moderate care but should not be used repeatedly on rocky or abrasive terrain.

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 Sea to Summit Comfort Light Insulated does not include recycled materials. Sea to Summit states it is striving to increase the use of traceable recycled materials in its products, but it does not provide any specifics.

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 Comfort Light does not contain Bluesign-approved materials, and Sea to Summit is not a Bluesign System Partner.

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 20% Bluesign-approved accessories.

The Sea to Summit Comfort Light Insulated sleeping pad comes with a repair kit, which is more comprehensive than others we’ve seen. It includes a spare valve insert along with the usual adhesive patches, so you’re covered for most mishaps.

Certain products can be used for longer if they come with a repair kit. Repair kits are designed for quick fixes, such as adhesive patches for sleeping pad punctures and replacement seals for inflation valves. These repair kits allow users to fix the item on the spot, continuing to use it instead of buying a new one.

Sea to Summit has a code of conduct for its suppliers that is enforced by the company’s product creation and supply teams as well as third-party auditors. The code of conduct is aligned with the International Social Accountability Labour Standard. However, that alone does not meet our requirements for responsible manufacturing. To receive credit in this category we require brands to be part of a third-party program that provides certification and/or annual audits of factories to ensure safe working conditions, fair wages, and a decreased environmental impact.

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.

As of 2025, Sea to Summit uses Forest Stewardship Council mix paper packaging for all of its airmats. It also uses recycled plastic mailers for shipments, with under a quarter of total packaging made with some amount of recycled content. Additionally, it earned a “Leading” rating from the Australian Packaging Covenant Organization.

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.

Sea to Summit has a robust repair program. The company will repair tents, sleeping pads, and sleeping bags covered under warranty free of charge or for a nominal rate for non-warranty repairs. It keeps fabric swatches available for users wanting to repair their gear themselves.

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.

Sea to Summit began tracking its greenhouse gas emissions in 2020 using the Greenhouse Gas Protocol. The company is in the process of establishing an emissions reduction target.

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.

Neither Sea to Summit nor its parent company, Five V Capital, publishes 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.
