Plus size winter fashion brand

Stoy by Killtec is a brand unlike any other in our collection. Meticulously designed and expertly crafted, Stoy winter coats and layers are here to adventure with you to the furthest northern and southern poles keeping you protected and dry in all kinds of extreme weather.

Travel through the winter with quality

To support the breathable outer material, many jackets have underarm ventilation. Thanks to the waterproofing rating of 10,000mm, you are well protected even from heavy rain.

STOY's Commitment to Sustainability

The entire STOY collection is free of perfluorinated and polyfluorinated chemicals (PFCs), known for their environmental persistence. Recognising the potential harm, we're actively collaborating with suppliers to explore PFC-free alternatives. Our goal is to achieve greater harmony with the environment and nature, making our products more sustainably aligned. Additionally, we prioritise durability, ensuring our jackets, crafted from high-quality materials, stand the test of time for long-lasting wear.
