The Patagonia Men's Nano Puff Jacket is a great Men's Jacket. If you find yourself out in the harsh cold or simply on your way to the shops on a cold day the Nano Puff is a great way of staying warm. It's light design gives you the warmth you need but without feeling like you're going to be weighed down.
Its made using highly compressible 60g PrimaLoft Gold Insulation (eco) with 100% recycled polyester, this may not sound out of this world but you haven't tried it!
We would always recommend using the Nano Puff as a mid layer on the Snow, it is waterproof but it won't stand up to the wet as well as a shell or outer layer would. A great choice of jacket to pair this is would be the Patagonia Snowdrifter Jacket (find it below).
