Two Piece 7% Merino Wool Blend Base Layer Set Thermal Underwear Skiing Cold Weather Quick-Dry Moisture Wicking Breathable

About this item

• SIZE GUIDE – ORDER BY SIZE CHART, NOT YOUR USUAL SIZE: The size tag sewn on the clothing follows Asian sizing and will SHOW ABOUT 2 SIZES LARGER than your ordered size (THIS IS NORMAL). Please choose your size based on the size chart measurements. This slim-fit women’s base layer set is designed for a close athletic fit for skiing, hiking, running, and winter sports.
• MERINO WOOL BLEND PERFORMANCE FABRIC – 7% WOOL: This is a performance wool blend base layer containing 7% wool, not 100% wool. The fabric combines wool with polyester, nylon, lyocell, and spandex to provide better stretch, shape retention, and durability than 100% wool thermal underwear. Unlike pure wool base layer sets that may stretch out and lose elasticity after workouts and washing, this women's merino wool base layer maintains its shape and flexibility for long-term use.
• ACTIVE THERMAL BASE LAYER – DESIGNED FOR MOVEMENT: Best for skiing, hiking, running and active use. Not designed as a heavyweight thermal for sitting still in extreme cold. This women’s thermal underwear provides warmth while remaining lightweight and breathable. Ventilation mesh at the chest, underarms, and back helps regulate temperature during activity.
• ADVANCED MOISTURE-WICKING & SEAMLESS COMFORT: Stay dry and comfortable with moisture-wicking one-way transport technology that pulls sweat away from your skin. Armpit 3D ventilation and honeycomb mesh panels accelerate evaporation to reduce post-workout chills. Seamless knitting minimizes friction and irritation, while targeted compression at knees and elbows provides support during skiing, hiking, and training.
• DURABLE & EASY CARE PERFORMANCE THERMAL SET: Built for long-lasting performance, this women’s thermal underwear set is machine washable and retains its shape after repeated washes. Natural wool fibers help reduce odor, while the stretch fabric keeps a secure fit even after intense activity. Ideal for skiing, snowboarding, running, gym workouts, and outdoor winter adventures.
