I don't know a lot about science and technology but I do know that things with "nano" in them are super techy and futuristic. Patagonia was spot on when they named their Men's Nano Puff Hoody. Techy and futuristic. This insulating layer utilizes compressible PrimaLoft® ONE to trap heat close to the body while not adding excess bulk. Synthetic insulation still functions even when wet making this a very useful layer in even the most severe conditions. The 100% recycled polyester shell can handle light moisture while blocking wind and can be layered effortlessly. Add into the equation the insulated hood and the fact the whole thing can stow into its own internal.... and you get the solution to your cold weather problems.
