Thickened Thermal Base Layer Set

This thickened thermal underwear set is designed for men and women who need reliable warmth and comfort during cold-weather outdoor activities. Combining a snug compression base layer with quick-dry performance fabric, it helps retain body heat while wicking moisture away from the skin, keeping you dry during hiking, mountaineering, skiing and winter camping.

• Thickened fleece-lined fabric for extra warmth in cold conditions
• Quick-dry moisture-wicking technology for high-intensity activity
• Four-way stretch compression fit that supports muscles without restricting movement
• Flatlock seams and soft stretch fabric to reduce chafing under outer layers
• Thermal top and legging set for men and women in matching sizes
• Cold-proof construction suitable for high-altitude and snow sports
• Lightweight, breathable and skin-friendly for long wear sessions
• Base layer that layers easily under jackets, vests and ski gear

Whether you are hitting the slopes for skiing and snowboarding, trekking the mountains, or camping through a winter night, this thermal base layer set provides insulation and dryness across changing conditions. The compression fit helps regulate temperature by trapping a layer of warm air next to the body while moving perspiration outward, so you stay comfortable instead of clammy.

Available as a partner-offered outdoor apparel set, this thickened thermal underwear is a versatile addition to any winter gear collection. Its smooth, low-profile design also works well as a mid-layer on colder days and as a standalone layer during active pursuits in mild weather. Pair it with breathable outerwear for a complete cold-weather clothing system built for performance.
