Cashmere Wool Silk Thermal Long Johns Set

This double-sided cashmere wool silk thermal underwear set combines the warmth of natural wool with the smooth comfort of silk for dependable autumn and winter protection. Offered through our marketplace partners, the set is designed as an cashmere long johns base layer for both men and women, delivering lightweight insulation that stays comfortable against the skin and layers easily under sweaters, shirts, suits, or ski gear.

Unlike ordinary fleece or cotton thermal wear, this set is knitted from a refined wool and silk blend with a cashmere-blended face on both sides of the fabric. The result is a soft, breathable layer that traps body heat while moving moisture away from the skin, so you stay warm without the clammy, heavy feeling of conventional winter underwear.

• Double-sided cashmere finish — a cashmere-blended face inside and out for a consistently soft, luxurious hand-feel
• Wool-silk insulation — natural wool warmth paired with silk smoothness for balanced temperature regulation in cold weather
• Complete two-piece set — includes a thermal top and matching long johns for men and women
• Thin yet warm construction — a slim silhouette that adds warmth without excessive bulk under clothing
• Soft rib-knit cuffs and waistband — helps the layer stay in place and blocks cold drafts
• Breathable, moisture-managing fabric — wicks perspiration and keeps you dry through long hours of wear
• Unisex, close-to-skin fit — suited to men and women across a broad range of sizes
• Durable natural fibers — a quality wool-silk-cashmere blend selected to hold warmth and softness season after season

Ideal for cold-weather layering — wear this wool silk base layer for winter commutes, offices that run cold, outdoor work shifts, hiking, camping, and snow days. It also works well as a mid-layer beneath a coat or as standalone thermal wear on chilly autumn mornings.

The cashmere thermal long johns set is a practical upgrade over standard thermal underwear, adding a refined touch of natural fiber comfort to everyday winter essentials. Neutral styling sits discreetly beneath clothing, making it a versatile addition to a men's or women's cold-weather wardrobe and a thoughtful gift for anyone who struggles to stay warm in the winter months.

Care and fit notes: Wash gently according to the care label and lay flat or hang to dry so the wool-silk blend and cashmere finish stay smooth and retain their insulating properties. Choosing your usual size delivers a snug fit that maximizes warmth; if you prefer extra room for layering, consider sizing up.
