I do all my hiking in the Patagonia Nano Puff jacket — and it's now on sale for 50% off at REI this Black Friday
The Patagonia Nano Puff Jacket is now just $118 at REI during the Black Friday sales. It's incredibly lightweight. So lightweight, in fact, that I can stash it in a day bag when I'm away hiking or in a small holdall when I teach outdoor fitness classes during winter.
