BRANWYN Continues to Push the Boundaries of Seamless Merino with the POWRspun™ Essential Compressive Leggings
October 1, 2025

The first leggings to deliver true seamless compression construction with over 75% ZQ-Merino wool in a performance blend
Bend, OR (October 1, 2025) /ENDURANCE SPORTSWIRE/ – BRANWYN, the brand known for redefining performance, comfort, and sustainability, proudly announces the expansion of its Seamless Merino collection with the launch of the Essential Compressive Leggings, now in two inseam lengths: 28-inch and the all-new 25-inch.
Building on the success of BRANWYN’s Seamless Merino Racerback Sports Bra, the Compressive Leggings bring a fresh, versatile foundation to women’s activewear. Designed for a second-skin fit, these leggings combine the natural comfort and sustainability of Merino wool with performance-driven innovation. Seamless construction and targeted compression move and sculpt with the body, whether as a baselayer for the mountain, a winter running tight, or navigating an everyday routine. BRANWYN’s Seamless Merino construction provides body-mapped shaping and contouring, while the proprietary POWRspun™ Merino blend delivers exceptional durability, breathability, and flexibility.
Key Features:
- POWRspun™ knit blend of 76% extra fine Merino, 14% nylon, and 10% elastane
- Superfine 17.5 Micron ZQ, OEKO-TEX 100, and RWS-certified Merino wool for next-to-skin softness
- Heavy-weight 4-way knit fabric moves with you
- Naturally odor-resistant for all-day freshness
- Merino wool is third-party certified PFAS, BPA, and forever chemical-free
“Our community loved the seamless innovation of our GLDNspun™ bras and underwear, so bringing that same technology to leggings was a natural evolution,” said Deanne Buck, CEO of BRANWYN. “Our POWRspun™ Compressive Leggings deliver even more targeted compression than our bras and underwear and are engineered for durability that stands up to the most intense workouts. The addition of the 25-inch inseam gives women more choice in finding their perfect fit without compromising on comfort, performance, or what’s best for their health and our planet. Our Compressive Leggings are a prime example of how we continue to push the boundaries of what’s possible in natural fiber performance fabrics.”
To better understand this innovation, Şeyma Çiğdem Uygun, Textile Engineer and BRANWYN’s Production & Sustainability Coordinator, shares a short Q&A:
Q: What makes the Essential Compressive Leggings technically different from other Merino wool performance wear on the market?
Uygun: Simply put, no one has ever achieved this level of seamless compression and performance with such a high percentage of ZQ-Merino wool. Most Merino activewear seamless blends lean heavily on synthetics to create structure and durability. We flipped that model. By using 76% superfine ZQ-certified Merino, paired with our proprietary POWRspun™ seamless knit technology, we’ve created leggings that deliver true compression, shape retention, and performance without sacrificing the natural softness and breathability Merino is known for. The result is one-of-a-kind: supportive, sustainable, and unlike anything else on the market.
Q: How did BRANWYN achieve compression without sacrificing breathability or freedom of movement?
Uygun: That balance is where the innovation lies. Traditionally, compression means tighter fabrics that trap heat and restrict movement. Our Merino-rich blend works differently. Our proprietary construction naturally creates supportive channels that hug the body while maintaining airflow and flexibility. Merino regulates temperature and resists odor, while nylon and elastane provide just enough reinforcement to enhance durability and recovery. What makes these leggings unique is that the compression doesn’t come at the expense of comfort. They move fluidly with you, and they breathe.
Q: What role did BRANWYN’s seamless knitting technology play in the design and feel of the Compressive Leggings?
Uygun: Seamless knitting was the key that unlocked this design. With traditional cut-and-sew methods, it’s nearly impossible to maintain such a high Merino content while still achieving compression. The seamless knitting construction utilizes specialized machinery to eliminate seams, resulting in a three-dimensional feel. The fibers are knit into tubes that become our bras, underwear, and now our compressive leggings; so, really, the fabric and the garment are created simultaneously. Our GLDNspun knit set the standard for seamless comfort in bras and underwear. But when it came to outdoor and activewear, we knew GLDNspun alone couldn’t deliver the level of support and compression needed.
That’s why we created POWRspun—a proprietary, brand-new knit engineered for higher performance. We set ourselves a tough goal: maintain 76% Merino while achieving the durability, structure, and compressive power activewear demands—all without forever chemicals.
We knew this would be challenging, and it took many rounds of samples to develop a knit that delivered the support and compression needed, thanks to the magic of a high percentage of Merino. Once we arrived, we knew we had something truly special.
The Compressive Leggings are available in sizes XS–XXL, with 28-inch (MSRP $158) and 25-inch (MSRP $148) inseam options. Available now at branwyn.com. For media inquiries, please contact Stacy Kline at stacy@darbycommunications.com.
