After the proliferation of synthetic insulating materials, in parallel with the old traditional down filling, there has been a real burst on the market of garments that are now generally termed "insulators". The greatest advantage of the new synthetic materials with respect to the traditional feathers is that they require much less care. The new, warm, light, and versatile pieces of clothing filled with synthetic materials are destined to be our inseparable companions of many outdoor adventures. 

I bought the first one about 10 years ago and, since then, I have never travelled without my insulator anymore. Whenever I was looking for some warmth and comfort, I have always found everything I needed in this very wise garment.

In recent years the evolution of this concept of clothes has led manufactures to produce a variety of different versions, more or less light, with or without a hood, etc. Insulators of different brands are all very similar, but there are a few ones that stick out of the crowd by doing something outstanding and innovative.

For this test I have chosen two insulators of two different brands utilizing different materials: Patagonia, which uses Primaloft, and Arc'teryx, which uses Coreloft.
