Ciele Athletics and Woolmark Collaborate on Winter Apparel and Headwear

October 7, 2025

Woolmark-certified Merino collection delivers performance-driven comfort for cold-weather running

MONTREAL (October 7, 2025) /ENDURANCE SPORTSWIRE/ — Canadian technical performance apparel brand Ciele Athletics has partnered with Woolmark to debut its first Woolmark-certified collection of Merino wool winter apparel and headwear. The line features Merino wool base layers, beanies and accessories designed for runners and adventurers of all kinds, blending Ciele’s run-specific design expertise with the proven durability, performance and quality standards guaranteed by Woolmark certification of Merino wool.

Ciele and Woolmark’s shared commitment to innovation, durability and sustainability form the foundation of the collaboration. By uniting Ciele’s design-led approach to running apparel with Woolmark’s global standard of excellence in Merino wool, the partnership delivers products that perform at the highest level while supporting athletes and protecting the planet.

Every Merino wool piece in the collection was designed by Ciele and independently tested through Woolmark’s global network of laboratories. Certification ensures the garments meet strict benchmarks across fiber content, colorfastness to light, durability, colorfastness to liquid, and laundering performance — a trusted mark of quality and longevity.

Ciele’s assortment of Woolmark-certified apparel includes the HLSTShirt and HLSLongsleeve, both versatile base layers made with Sorino | WS, a premium Merino and silk-blend fabric that also provides UPF +30 protection. Nearly all of Ciele’s current beanies are now Woolmark certified, including key styles such as the CXBeanie, ACBeanie, SKLBeanie and TRBeanie, along with cold-weather essentials like the HLSBalaclava and HLSNecktube.

Merino wool brings natural performance benefits that make it ideal for running and outdoor training:

• Temperature regulation for performance across shifting conditions
• Dynamically breathable fibers that adapt in changes to body temperature
• Soft next-to-skin feel, finer than human hair
• Moisture-wicking and odor-resistant properties for long-lasting comfort

Beyond performance, the Merino wool fiber is renewable, biodegradable, natural and recyclable. Merino wool is grown year-round by Merino sheep consuming a simple blend of ingredients including sunshine, water, fresh air and grass. Once Merino wool is disposed of, the fiber readily decomposes in soil, returning nutrients to the earth. Its exceptional durability extends the longevity of each garment, reinforcing Ciele’s B Corp mission to create high-performance apparel that endures and protects while minimizing environmental impact.

“At Ciele Athletics, quality, care and considered design guide everything we create,” says Ciele Athletics CEO Jano Arabaghian. “Our partnership with Woolmark builds on that commitment by bringing Merino’s natural performance and sustainability to runners and athletes everywhere in a collection built to last, designed with purpose and certified to the highest standards.”

“Merino wool is a natural high performer, making it the ideal choice whether you’re hitting the pavement for your daily run or competing in your next marathon,” says Woolmark Managing Director John Roberts. “We are thrilled to partner with Ciele Athletics to push the boundaries of Merino wool to develop Woolmark-certified functional performance apparel and headwear for the everyday athlete.”

Ciele Athletics’ Woolmark-certified apparel and headwear is now available for purchase via CieleAthletics.com, at espace | MTL and at select retailers globally.
