The Black Diamond Solution 150 is rated relatively low for sustainability, meeting just a few of our criteria. While the Solution 150 uses non-mulesed wool, which ensures sheep are not harmed in the shearing process, it does not adhere to the Responsible Wool Standard (RWS). On the plus side, the Solution 150 earns a high longevity score.


At the brand level, Black Diamond shows a mix of progress and gaps in its sustainability efforts. The company recently released its first impact report, outlining its efforts to reduce its environmental impact. It tracks its emissions using the Greenhouse Gas Protocol but does not publicly report greenhouse gas data. The brand recently set the goal to reduce its carbon intensity by 50% by 2030, but does not provide any more specifics. On the bright side, Black Diamond has reduced its packaging for some product categories and uses partially recycled cardboard. The brand also offers repair services regardless of warranty status for many of its products through its Reroute program. Unfortunately, Black Diamond does not provide a resale or recycling program for used apparel.


Below, we break down in detail all of the Solution 150'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 base layers and our review of the Solution 150.

The Solution 150 uses Nuyarn technology, which features a synthetic fiber core wrapped in merino for softness and odor resistance. Despite its lightweight 150-gram thickness, the sleek face fabric resists abrasions well and is more robust than most merino blends in the same weight class. As a result, the Solution 150 should hold up to multiple seasons of regular 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.


There are two leading certification systems for sustainably sourced wool in the outdoor industry: the Responsible Wool Standard (RWS) and ZQ Wool. The Responsible Wool Standard, set by The Textile Exchange, ensures wool suppliers follow best farming practices, including sustainable land management and animal and social welfare. ZQ Wool provides similar environmental and social standards and supports a network of growers who aim to sequester more carbon than they emit. Some brands use less widespread equivalent certifications, which we consider when appropriate.

Black Diamond does not appear to work with any third-party factory certifications or audit programs. The company has its own vendor code of conduct, but that alone is not enough to meet our criteria for this category. To meet our responsible manufacturing criteria, 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.

Black Diamond uses 35% recycled cardboard for packaging and 100% recycled paper for all apparel hang tags. The company is making efforts to reduce packaging within specific product categories. For example, from 2019 to 2021, packaging for trekking and ski poles decreased by 46%.

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.

Through its Reroute program, Black Diamond will recycle old carabiners into trekking poles. However, they do not offer recycling programs for other products.

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.

Black Diamond tracks greenhouse gas emissions using the Greenhouse Gas Protocol and has set a goal to reduce its total carbon intensity by 50% by 2030. However, Black Diamond does not publicly share specific details about its company-wide emissions tracking. Its impact report highlights significant reduction efforts at two of its major production facilities through the use of renewable energy and more efficient systems, but it does not provide an overview of the company’s Scope 1, 2, or 3 emissions reductions.

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.

Black Diamond published its first impact report in 2025. The report has a dedicated section on sustainability, which covers information on its preferred material goals, waste reduction, energy efficiency practices, circularity efforts, and more.

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.
