SIMIYA Women Thermal Underwear Set Long Johns for Winter 🧦
Description:
This thermal base layer set offers lightweight warmth and stretch so you can stay active through chilly days and cool nights. The fleece-lined long sleeve top and matching leggings combine a soft polyester blend with elastane to trap heat while allowing movement, making them suitable for layering under outdoor kit or for cosy nights at home. 😊
Key Points
The fabric mix is 95% polyester and 5% elastane, with a soft fleece lining that adds insulation without bulk. The long johns fit like a second skin to reduce heat loss while remaining breathable and quick to wick moisture away from the skin. This helps keep you dry during moderate activity and prevents that clammy feeling many thermals cause.
Elastic four-way stretch and reinforced seams give freedom of movement and durability, so the set performs during running, cycling and other winter workouts. The design is discreet enough to be worn under everyday clothes and comfortable enough to be used as sleepwear on colder nights. Consider that thicker outer layers may still be needed in very low temperatures, according to the manufacturer.

Usage Recommendations
For outdoor exercise, wear the set as a base layer under your usual activewear to trap heat while allowing sweat to move outwards. For lower intensity activities or everyday use, pair the leggings with thicker socks and insulated trousers when needed. The top layers well beneath coats and jackets without adding bulk, and can be used as comfortable nightwear when temperatures drop.
If you plan longer exposure to wet conditions or very low temperatures, add a windproof outer shell or thermal mid-layer for better protection. The fabric is designed for easy care but follow garment labels for washing instructions to preserve the fleece lining and elasticity. 🧣.
