kidney warmer
The best for your health: merino wool with copper
The fine merino wool is the finest wool from a sheep, and we use only 100% Öko-Tex-certified quality, guaranteed to be processed mulesing-free. The wool has the advantage of being odor-inhibiting and breathable and absorbs sweat, so the accessories function like an air conditioner. Despite all this, the material is gentle on the skin and provides natural warmth.
The combination of the ultra-thin copper threads and the finest merino wool combines the valuable properties of both materials and gives you a comfortable-to-wear, functional wool garment with plenty to offer.
Soft and snug-fitting, our copper kidney warmer made from 100% Öko-Tex® certified merino wool with fine copper threads, pleasant warmth around your midsection. Worn directly on the skin under clothing, it keeps your kidneys, bladder, and intestines warm.
You can comfortably turn down the heating with your new favorite pieces, because this powerful item from Bolter keeps more than just your feet warm.
