How to Choose the Best Thermal Underwear for Women
- INSULATION & MATERIAL: If you’re gearing up for a ski or snowboarding trip or just want to revel in perfect warmth at home, one of the most important features you should thoroughly check is the insulation. But if you’re making your choices through online stores, it might be difficult to tell which has the excellent insulation and which does not. Having said that, the material is a fundamental factor that needs to be greatly considered. The popular materials used in manufacturing thermal underwears are fleece, wool, polyester blends, cotton, and microfiber blends. Fleece and polyester blends, however, can provide optimum warmth and comfort and the ideal choice of most users. They are good at wicking the moisture away, provide ample ventilation, and are lightweight. The insulation and overall quality, however, may still vary according to the brand or fabric blends.
- COMFORT & FIT: Thermal underwears are designed with a snug fit but without a constricting feel. As a base layer, they shouldn’t be too loose but rather embrace the skin lightly and comfortably. These underwears are tailored with elastic waistlines and sometimes, made from a fabric with a spandex blend to make sure they are stretchable and can be easily worn together with layers of clothes. And to fully benefit from the utmost comfort and snug fit, be careful in choosing the size.
- MAINTENANCE: While many users rave about the benefits of thermal underwears, some feel otherwise thus complain about their durability. Unless proper care is applied, damages are inevitable and keeping the quality of a thermal underwear in its good condition can be a struggle. Do know that every type of fabric has specific care and maintenance guidelines that should be closely followed to prevent pilling, tears, or any damages. Handwashing or using a washing machine at a gentle cycle and a mild detergent would be another effective way to retain the pristine quality of the fabric.
It is better not to skimp on thermal underwears when you’re looking for exceptional comfort and warmth during the freezing temperatures in winter. But as the options may be overwhelming, finding the best thermal underwear might seem quite difficult.
