The new Razor Vest is a superior insulated hunting top. It has been designed primarily for hunting purposes, so it's tougher than your usual puffer but just as at home around town. Primaloft Thermoplume has an ethical fill that is just as warm as down when it's dry but continues to perform when wet. With a tough water-resistant outer and cleverly placed seams to increase weather resistance, it feels like being wrapped up in a warm sleeping bag and it looks razor sharp. The Razor vest has a more slippery/shiny outer fabric than the Razor jacket. This fabric stops the vest from binding when worn under an outer layer, which can result in the vests baffles being twisted and squashed, meaning loss of heat.
Down is treated as a commodity and the price fluctuates about as much as petrol at the gas station, depending on supply and demand. Couple that with not really knowing whether your down is from a sustainable and responsible source, or has come from a less desirable live plucked source, and down is looking less and less desirable as a technical hunting option.
Our search for a responsible down product lead us to a brand new product from Primaloft called Thermoplume. This is a new fill that is 100% synthetic, yet it behaves just like down, with similar warmth to weight and packability but far superior performance to any down (water resistant or not) in wet weather and in breathability.
