VIATERRA Mid-Layer Thermal Jacket Boreal Graphite

• Pre-shaped ergonomic design offers seamless layering comfort under your riding jacket without restricting movement.
• Triple-layer construction with a thermal fleece core traps body heat while blocking wind for optimal winter warmth.
• Elasticated cuffs, close-fit collar, and adjustable hem provide a snug, stay-in-place fit without bulk.

Material

Built with a triple-layer soft shell fabric and a brushed fleece inner lining, the Boreal offers exceptional warmth without excess bulk. The exterior resists wind and light rain, while the soft inner layer traps heat effectively. High-stretch panels at the sides and underarms improve mobility and layering comfort during long hours on the road.

Warmth and Insulation

The Boreal is designed for winter rides and high-altitude terrain. Its thermal fleece core provides consistent insulation across the torso and arms, helping retain body heat without overheating. Elasticated cuffs and a contoured collar seal out cold air, keeping you warm during early-morning starts or wind-chilled descents.

Comfort and Fit

The pre-curved Focus Fit silhouette ensures a body-hugging fit that works seamlessly under an outer shell. Articulated sleeves and stretch panels at high-movement zones allow unrestricted motion, while the drop-tail design keeps your lower back covered when leaned forward in a riding position. Adjustable hem toggles give you control over fit and retention.

Care and Storage

1. Wipe clean with a damp cloth and lukewarm water – do not use hot water.
2. Avoid contact with solvents, fuel, fabric softeners, or alcohol-based cleaning agents.
3. Always dry on a hanger in a ventilated area, away from direct sunlight or heat sources.
4. Ensure the mid layer is completely dry before storing to prevent mildew or fabric damage.
5. Clean and lubricate zippers regularly using vaseline or candle wax.

Things to remember

1. The Boreal is designed as a snug mid layer – meant to sit close to the body for optimal insulation and easy layering under an outer jacket. It shouldn’t feel bulky or loose.
2. Wear it on a few rides to let the fabric adapt to your posture. Use the hem toggles and zipper fully closed for best heat retention.
3. Store it flat or hang it in a ventilated space.
4. Avoid compressing for long periods to maintain the loft and performance of the thermal fleece lining.
