FAQ: Women's Thermal Underwear
How do I choose the right size? Should it be tight?
Yes, thermal wear is designed to be "Skin Tight" or like a second skin. The scientific reason is to prevent cold air from entering between the fabric and your body, trapping natural body heat. If loose, it loses its insulating function. However, it shouldn't be so tight that it restricts circulation. Choose your usual size, ensuring the fabric contains "Spandex" or "Elastane" for flexibility.
What is the difference between Fleece Lined and Regular Cotton?
Regular cotton is comfortable but absorbs moisture and holds it, which can make you feel cold if you sweat. Fleece lining is a technology using soft synthetic fibers that trap warm air pockets and wick moisture away. For very cold weather, Fleece is the undisputed winner, while cotton suits mild weather or home wear.
Can I wear these sets under evening gowns or formal workwear?
Absolutely, but it depends on the outer clothing. For tight or light-colored clothes, we recommend "Ultra Thin" sets in beige/nude (like Product #10). For open-collar clothes, look for Scoop/Deep Neck designs. Thick velvet sets are better suited for abayas, coats, and winter sportswear.
How do I care for thermal wear to make it last?
Most thermal fibers are sensitive to high heat and bleach. To maintain elasticity and insulation: 1. Wash in cold or warm water (30°C). 2. Avoid Fabric Softener as it can clog fibers and reduce sweat-wicking. 3. Air drying is best, or tumble dry on very low heat. 4. Do not iron directly.
