THE FIRST LAYER DOES THE QUIET WORK

Warmth Starts Before the Jacket Goes On.

Heavy outerwear can block the weather, but the layer sitting against your body is what helps manage warmth and moisture while you move.

The fleece-lined construction adds a soft insulating layer without the bulky profile of another sweatshirt or pair of heavy pants.

Soft Fleece Interior Adds cozy warmth against the body on cold-weather days.
Close Base-Layer Fit Designed to sit underneath pants, ski gear and winter jackets.
Less Layering Bulk Warmth without adding another loose, heavy outer garment.

SOFT ON THE INSIDE

Fleece Where Cold Weather Actually Reaches You.

The inner surface uses a plush fleece texture designed to feel soft against the skin while adding an insulating layer for cool and cold conditions.

That makes it a practical first layer for long mornings outside, winter commutes and cold-weather recreation.

Dual-layer thermal fabric with exterior and fleece interior
WARMTH + MOISTURE MANAGEMENT

Cold Outside Doesn't Mean You Want Sweat Trapped Inside.

The product combines a smoother outer face with a breathable fleece interior to balance insulation with moisture movement.

That matters when winter activity shifts between standing still, climbing, walking and working.

MOVE WITHOUT STAYING DAMP

Built for the Part of Winter When You Start Sweating.

The breathable, moisture-wicking fabric is designed to move perspiration away from the body more efficiently than a heavy absorbent layer.

That helps the base layer feel more comfortable when your activity level rises.

STRETCH WITH THE MOVEMENT

A Base Layer Should Follow You—not Fight You.

Four-way stretch lets the fabric move through bending, climbing, skiing and everyday work without relying on a loose cut.

The compression-style fit stays close to the body so it layers more cleanly underneath outer garments.

Prefer a Relaxed Fit?

The current product guidance says the style has a compression fit. If you prefer more room, consider selecting one size larger than your usual close-fitting base-layer size.

Check the Exact Style Name Before Ordering

The current product selector contains several fleece-lined styles. Some options are explicitly labeled “Set” or “Two-Piece Set,” while others use individual style names. Choose the exact Shopify variant you want from the selector rather than assuming every option has the same package configuration.

HELP THE FLEECE STAY SOFT

Wash Cold. Use a Gentle Cycle.

The current product guidance recommends cold water and a gentle wash cycle. Gentler care can also help reduce unnecessary linting and wear on the fleece surface.

Cold Water Avoid unnecessary high-temperature washing.
Gentle Cycle Helps protect stretch fabric and fleece texture.
Follow the Garment Label Use the sewn-in care instructions as the final care guide.
GOOD TO KNOW

Before You Layer Up.

Is the inside fleece lined?
Yes. The current product description and imagery highlight a soft fleece interior designed to add warmth for cold-weather layering.
Is the fit tight?
It is designed as a compression-style base layer, so it fits closer to the body than normal casual clothing.
What if I prefer a looser fit?
The current product guidance suggests considering one size larger if you prefer a more relaxed fit.
What sizes are currently offered?
The current selector offers S, M, L, XL, XXL and 3XL.
Is every style a two-piece set?
Do not assume so. The current style selector contains options explicitly named “Set” or “Two-Piece Set” as well as styles without that wording. Check the exact variant title before ordering.
What activities is it suitable for?
The current product description lists skiing, snowboarding, winter hiking, fishing, outdoor work and other cold-weather activities.
Does it have a published temperature rating?
The current product page does not publish a reliable minimum temperature rating. Warmth needs vary with activity level, weather conditions and the rest of your layering system.
How should I wash it?
The current care guidance recommends cold water on a gentle cycle. Follow the garment's sewn-in care label for final instructions.
