SlimCOOL PowerArms

Cooling helps with weight loss. This has been scientifically proven through a number of research studies.

We have developed SlimCOOL technology and integrated it into clothing so that you don’t have to bathe in ice. The technology cools the T-shirt and other products effectively with 660 watts to between 18-20 ° C. At this temperature, scientifically proven brown fat is activated and assists you in losing weight. Simply wear the garment at home or elsewhere and whenever you have the time to optimise your physique.

We refer to them as "bingo wings" but whatever country you’re in,  they are not very popular. That's why we gave this area some thought. Even if it is not a "simple fat problem", we know that less fat in this area would also be visually advantageous!

It is important that you use the SlimCOOL PowerArms in combination with the SlimCOOL PowerShirt for the best cooling effect so that the total cooling surface is large enough.

Simply activate with 0.25 liters of tap water for 5-10 seconds, dry and fasten.

Measure your upper arms, select the right size and order!

SlimCOOL cooling clothing is - unlike most other cooling functional textiles - washable. All our products are washable by hand or in a wool wash cycle -  without spin-drying -  at 30 °C with the special detergent 'DEOXX® ecowash' (alternatively: TOKO® ecowash) developed for our refrigeration functional textiles. Many other commercially available pH-neutral liquid detergents are also suitable, but we can not guarantee this due to the different chemical compositions.

Please note the instructions enclosed with the product.
