Refined yet rugged, the Winter Wool Collection is built for cold-season performance and life in the Maine climate. Crafted in the USA from 220 gsm Nuyarn® merino wool fleece, these pieces deliver the warmth of traditional fleece without the bulk or weight. Whether you’re layering up for a frosty gravel ride, hiking through snow-dusted trails, or relaxing fireside after a long day outdoors, Winter Wool keeps you warm, dry, and comfortable in all conditions.

This is merino wool, reimagined for winter adventure.

The Winter Wool Collection represents Pinebury’s most insulating lineup yet. Each garment features a brushed merino interior that retains heat naturally, paired with a smooth jersey face that resists wind and wear. The result is a soft, breathable fleece that performs across a range of temperatures and activities.

Despite its warmth, Winter Wool never feels bulky or heavy. It layers effortlessly under a shell, over a base layer, or on its own. Whether you’re running through sleet or pedaling to work on a cold morning, the balance of warmth and mobility is what makes this collection stand apart.

At the heart of every Winter Wool piece is Nuyarn®, a patented spinning technology that transforms merino wool into a stronger, loftier, and more responsive fabric. Instead of twisting fibers tightly, Nuyarn drafts merino around a performance filament core—creating a structure that’s lighter, stronger, and dries up to five times faster than conventional wool.

This unique construction enhances stretch and recovery, improving comfort and shape retention over time. You get the natural benefits of merino—odor resistance, moisture management, and thermoregulation—with the added durability and longevity needed for daily wear and demanding adventures.

Our winters are unpredictable—icy mornings on the coast, heavy snow in the mountains, crisp air that lingers long into spring. The Winter Wool Collection was designed to handle all of it. Every detail, from the flatlock seams to the smooth, abrasion-resistant outer face, was considered with performance and longevity in mind.

Whether you’re cycling the frozen backroads of southern Maine, skiing snow-covered trails of western Maine or hiking through Acadia’s snow-covered trails, Winter Wool delivers the comfort and protection you need without compromise.

Like all Pinebury garments, the Winter Wool Collection is proudly made in the USA, from fabric to final stitch. We work with trusted partners who share our values of craftsmanship, sustainability, and quality. Our 220 gsm Nuyarn® merino fleece is knit in North America and sewn in small batches by skilled makers who take pride in their work.

By keeping production close to home, we minimize waste, ensure fair labor, and maintain the highest standards of consistency. It’s better for people, better for the planet, and better for your gear.

Designed for Versatility

Winter Wool was built to perform—on the bike, on the trail, and everywhere in between.

• Winter Wool Hoodie: Soft, warm, and breathable. The perfect mid-layer for layering under a shell, over a base layer, or wearing on its own. Designed with a smooth face to resist wind and wear, and a brushed interior for natural insulation.
  
• Winter Wool Crewneck: Streamlined and understated. A versatile fleece pullover with a classic fit that transitions seamlessly from the outdoors to everyday life.
  

Each piece combines comfort and function, with subtle Pinebury details and timeless styling that looks just as good off the bike as it feels on it.

Sustainable by Nature

Merino wool is a renewable, biodegradable fiber that leaves a lighter footprint than synthetic alternatives. By pairing merino with advanced Nuyarn® technology, we’ve created a fabric that performs better and lasts longer—reducing the need for replacements and keeping more garments out of landfills.

Every decision we make, from fiber sourcing to packaging, reflects our commitment to sustainability and responsible manufacturing. Winter Wool is not just built for winter—it’s built for the long haul.

Why Choose Merino Wool Fleece

Unlike synthetic fleece, which traps moisture and odor, merino wool naturally regulates temperature and wicks moisture away from the skin. Even when damp, it retains warmth and resists odor buildup, keeping you comfortable during long, active days outdoors.

• Thermoregulating: Keeps you warm when it’s cold, cool when it’s warm.
  
• Moisture-Managing: Wicks sweat and dries quickly for consistent comfort.
  
• Odor-Resistant: Naturally resists odor even after repeated use.
  
• Soft & Non-Itchy: Fine merino fibers are smooth and comfortable against the skin.
  
• Durable: Nuyarn® construction improves strength and longevity.
  

Tested in the Maine Outdoors

Every Pinebury product is tested where we live and ride—across Maine’s rugged coastlines, forest roads, and mountain trails. The Winter Wool Collection was born from those conditions: long gravel rides in freezing temperatures, snowy hikes in the White Mountains, and quiet winter mornings in the woods.

We don’t just design clothing for the outdoors. We live it, every day.

Built for the Long Season Ahead

From November’s first frost to April’s last ride, Winter Wool keeps you prepared for whatever the season brings. Pair the hoodie or crewneck with a Pinebury merino base layer for added warmth, or wear them solo for cozy comfort around town. However you spend your winter—riding, skiing, exploring, or simply staying warm—these pieces are made to keep up.

Invest in Quality. Invest in Comfort.

Performance shouldn’t mean plastic. Pinebury’s Winter Wool Collection offers a natural alternative to petroleum-based synthetics—bringing together warmth, comfort, and timeless style in one sustainable package.

These aren’t throwback fleece layers. They’re the next evolution in merino wool performance.
