SIMIYA Women's Thermal Base Layer Set

The SIMIYA women's thermal underwear set offers exceptional warmth and comfort to conquer the cold winter. Crafted with a meticulously selected fabric blend of 92% Polyester and 8% Spandex, this thermal underwear set delivers unparalleled performance.

[Fleece Lined]: The fleece inner layer creates an insulating air pocket, trapping heat efficiently while allowing moisture to be easily breathed away by the skin. This unique design ensures you feel as cozy and comfortable as basking in the warm spring sunshine, even in the depths of winter.

[Selected Fabric]: Engineered to the highest international yarn standards, the fabric is soft, non-pilling, and anti-static, without the use of chemical dyes that could cause unpleasant odors. The moisture-wicking properties of the fibers make the thermal underwear easy to clean and quick to dry.

[Light & Formfitting]: Designed to be a second skin, the women's long underwear is remarkably lightweight and ultra-soft, allowing for complete freedom of movement without any bulkiness beneath heavy outerwear. Whether lounging at home, working in the office, or venturing outdoors, this thermal base layer delivers a comfortable and suitable wearing experience, bidding farewell to the winter chill.

[4-WAY Stretch]: Exceptional horizontal and vertical stretch enables natural, unrestricted movement, ensuring the long johns never bunch up or feel restrictive, no matter the activity – hiking, skiing, camping, or everyday errands.

[Certified Durable]: The strong, flexible Spandex component retains its shape and extensibility, preventing shrinkage or deformation. The color fastness is also long-lasting, so you needn't worry about fading during washing, whether by hand or in the laundry bag.
