Fostex Garments Thermo Underwear Set “Extreme”: Maximum Warmth as a Base Layer

The Fostex Garments “Extreme” thermo underwear set is specially designed to keep you warm and comfortable during the most challenging weather conditions. Whether you are going on a winter sports holiday, working outdoors, or taking a winter walk, this set is the perfect first layer for your outdoor gear.

This complete set consists of a long-sleeved thermal shirt and matching thermal pants, finished in a classic white color.

High-Quality Material: Made from 100% polyester, which provides excellent thermal properties and effective moisture wicking.
- Lightweight Comfort: With a total weight of only about 400 grams, the set feels light on the body, ensuring maximum freedom of movement.
- Breathability: The material retains body heat while wicking away excess moisture to prevent clamminess.
- Fit: Designed to be worn close to the skin for optimal insulation.

The biggest advantage of the “Extreme” set is the balance between heat insulation and moisture regulation. Polyester is an ideal fabric for active users because it dries faster than cotton and keeps your skin drier during physical exertion. The set is compact to store and adds minimal bulk under your normal clothing or sports outfit.
