Ciele Athletics Introduces a New Woolmark-Certified Collection

Ciele Athletics, the performance running brand from Montreal, Canada, introduces its second Woolmark-certified collection, bringing the natural performance properties of Merino wool to technical cold-weather apparel and accessories. Built around the brand’s Sorino™ natural fiber platform, the collection combines Merino wool and silk base-layers with a range of Merino wool headwear designed for temperature regulation, moisture management and comfort across changing conditions.

At the core of the collection is Sorino | WS, a Merino wool and silk blend featured across Ciele’s HLS base-layer system and accessories, including face masks, neck tubes and balaclavas. Merino wool naturally helps regulate body temperature, manage moisture and resist odor, while silk contributes a smooth hand feel and lightweight strength. Together, the fibers create a next-to-skin layer designed to maintain comfort as temperatures and activity levels change.

The collection extends these Merino material benefits to cold-weather headwear, with Woolmark-certified beanies across four styles: CX, SKL, AC and VNT. Made with Sorino | W, a 100% Merino wool yarn, the styles draw on wool’s natural ability to regulate temperature and manage moisture while resisting odor without chemical treatments. Designed for repeated wear, the beanies offer functional versatility across cold-weather conditions.

Ciele’s continued partnership with Woolmark reflects a shared commitment to material quality and considered product development. As a B Corp-certified company, Ciele approaches performance through an ongoing effort to find better solutions across its products, manufacturing partnerships and broader community. Working with Woolmark builds on that ethos, pairing Ciele’s performance-driven approach with Woolmark’s expertise in Merino wool quality and product standards.

As a global authority on wool, Woolmark works across the wool supply chain, connecting Australian Merino woolgrowers with the textile and apparel industries. Its certification process provides independent verification that products meet established standards for fiber content, colorfastness, durability and laundering performance. This process provides an additional measure of quality and longevity, reinforcing the standards behind Ciele’s technical run-specific designs.

With its second Woolmark-certified collection, Ciele continues to prioritize the use of natural fibers in technical running gear, bringing together material performance and functional design in a versatile range of cold-weather layers and accessories for runners and outdoor enthusiasts.“We make things to be worn hard and kept for a long time,” shares Ciele Athletics Co-Founder, Jeremy Bresnen. “Woolmark has set the standard for quality wool for decades. Certifying key pieces in our collection, from our performance base layers to select accessories and every knit beanie we make, puts that standard on each one.”

“Ciele’s second Woolmark-certified collection shows how Merino wool can work across a complete performance system. Combining Merino wool and silk in lightweight, close-fitting base-layers, with additional Merino wool and wool blend accessories extends the collection into cold-weather protection. It is a considered, product-led approach to designing for performance,” says Woolmark Managing Director Bryan Fry.

Products are now available purchase via CieleAthletics.com, at Ciele’s flagship store, espace | MTL (1630 R. Notre Dame O, Montréal, QC H3J 1M1, Canada), and at select retailers globally.
