Why FELTFORMA
Seamless Sculpted Construction
Each piece is hand-shaped using traditional wet felting - forming dense, durable wool without glued seams or synthetic reinforcement. Designed for consistent thermal regulation in sauna, cold plunge, and everyday use.
Natural Wool. No Synthetics. Built for Heat, Cold & Everyday Comfort.
Undyed Tyrolean Mountain Wool
Our wool comes from small European farms and is washed only with water - never bleached, dyed, or chemically softened. Naturally breathable, insulating, and plastic-free for safe use in high and low temperature environments.
Crafted in Europe by Hand
Every sauna hat and wool slipper is individually formed in Lithuania - never factory produced. This ensures proper density, structural integrity, and long-term durability under extreme heat, cold, and daily wear.
Plastic-Free & Glue-Free
No synthetic fibers. No plastic layers. No adhesives. Only natural wool shaped for temperature regulation and everyday comfort.
FELTFORMA specializes in non-toxic wool sauna hats and organic wool slippers designed for temperature regulation and plastic-free living.
Seamless undyed wool sauna hats hand-sculpted from raw mountain sheep wool. Designed for sauna heat, cold plunge immersion, and year-round contrast therapy - free from dyes, synthetics, glue, or chemical processing.
