Refined yet versatile, the Merino Wool Trail Suit is built for movement, recovery, and everyday life. Crafted in the USA from 220 gsm Nuyarn® merino wool fleece, this matching set delivers the warmth of traditional fleece without the bulk or synthetic feel.

Designed as a complete merino wool set, the Trail Suit pairs our Winter Wool Hoodie or Crewneck with the Winter Wool Jogger for a cohesive system that transitions effortlessly from trail to town. The brushed interior provides natural insulation, while the smooth face resists wind and wear. Comfortable and warm but breathable, it performs across changing conditions from early fall through late spring.

This is merino wool, reimagined for modern movement.

A Merino Wool Sweatsuit, Refined for Three-Season Wear

The Pinebury Merino Wool Trail Suit brings together our Winter Wool Hoodie, Crewneck, and Jogger Sweatpants into one cohesive, performance-driven matching set. Made from 220 gsm Nuyarn® merino fleece, the Trail Suit delivers natural warmth, breathability, and durability without the weight and bulk of traditional fleece.

This is not a synthetic sweatsuit. It is a technical merino wool set designed for movement, recovery, travel, and everyday life.

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 Merino Wool Trail Suit is proudly made in the USA. Our 220 gsm Nuyarn® merino fleece is sewn in small batches by skilled American makers who share our commitment to craftsmanship, sustainability, and long-term quality.

By keeping production close to home, we reduce waste, maintain oversight, and support responsible manufacturing. It is better for the people who make it, better for the planet, and better for the gear you rely on season after season.

Designed for Versatility

The Merino Wool Trail Suit was built to perform on the bike, on the trail, at the lodge, and everywhere in between.

Winter Wool Hoodie

Soft, warm, and breathable. The perfect mid-layer for wearing under a shell, over a base layer, or 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 merino fleece pullover that transitions seamlessly from the outdoors to everyday life.

Winter Wool Jogger Sweatpants

Relaxed through the hip with a tapered leg for a clean, athletic fit. Comfortable and warm but breathable, with secure pockets and a natural twill drawstring. Designed for three-season wear.

Together, they form a complete merino wool sweatsuit that moves easily between activity and recovery without sacrificing performance or style.

Sustainable by Nature

Merino wool is a renewable and biodegradable fiber that leaves a lighter footprint than petroleum-based synthetics. By pairing fine New Zealand merino wool with advanced Nuyarn® technology, we create a fabric that is stronger, longer lasting, and more performance-driven than traditional wool.

Fewer replacements. Longer lifespan. Less waste.

Every decision, from fiber sourcing to packaging, reflects Pinebury’s commitment to sustainability and responsible manufacturing.

Why Choose a Merino Wool Trail Suit

Unlike synthetic fleece that traps moisture and odor, merino wool naturally regulates temperature and manages moisture.

Thermoregulating

Keeps you warm when temperatures drop and comfortable when you are on the move.

Moisture Managing

Wicks sweat and dries efficiently for consistent comfort.

Odor Resistant

Naturally resists odor during multi-day wear.

Soft and Non-Itchy

Fine merino fibers feel smooth against the skin.

Durable

Nuyarn® construction improves strength, rebound, and long-term performance.

This is the next evolution of the classic tracksuit, built with natural performance instead of plastic.

Tested in the Maine Outdoors

Every Pinebury product is tested where we live and ride across Maine’s forest roads, coastal trails, and mountain terrain. The Merino Wool Trail Suit was shaped by long gravel rides in cool air, early morning trail runs, shoulder-season hikes, and quiet recovery days after winter adventures.

We do not design clothing for a lifestyle we imagine. We design it for the one we live.

Built for the Long Season Ahead

From early fall through late spring, the Merino Wool Trail Suit adapts to changing conditions. Layer it under a shell for skiing or cold-weather riding. Wear it on travel days. Pull it on after a long effort. Or wear it as your everyday uniform when comfort matters most.

Invest in quality. Invest in comfort. Invest where it matters.
